Lincoln Towncar

repair or replace motor?

Drivers seat that wont go up or down

First determine if the motor is getting power from the switch. And if not, is the switch getting power. If you find the switch operating as it should and power getting to the motor, it may need to be replaced. Next, check all connections and test motor with both battery positive and negative.

The up and down function wires coming from the switch are RED/LT GREEN and YELLOW/LT GREEN. The black wire on the switch is connected to battery negative(ground). Use the wiring diagram provided to get an idea of how the circuit works.

2009 VW Tiguan

This car was manufactured in Slovinia, originally purchased in Canada, sent to Ghana where our NGO purchased it in 2014. Soon after, the EPC light came on and we have tried many things and continue to have problems.

The problem: EPC light comes on and sometimes there is not a problem, but most times, the car stops pulling. This can happen anytime – when the car is cold or when it has been running. YOu have to stop, turn off the car, wait and try and eventually, it will go again, sometimes for many miles or days, and sometimes just for a few minutes before you go again.

What we have replaced up until now:
Replaced: Throttle position sensor, APPS, coils 1 & 4 (I am told they were short circuiting), plugs, release bearing/clutch kit (a separate problem, I guess).

The error codes:
P0130A (?)

They report carbon buildup in the injectors ( I think they saw when they removed the intake manifold) are recommending we replace all of those and many more items.

I appreciate your help!

Multiple Trouble Codes Detected

Quite an assortment of codes you have going on. The P0300 codes are for misfires. The other codes have to do with the TPS and Intake Sensors. Looking at the big picture it appears there is an electrical issue. The electrical issue is most likely tied to the wiring harness. If this vehicle has been in a wreck, start looking in that area for pinched or damaged wiring. Look for corrosion on connectors and at the connections at the ECM and the sensors involved.

Code P1558 – Throttle Actuator Electrical Malfunction

Possible causes

  • Faulty Throttle Valve Control Module
  • Throttle Valve Control Module harness is open or shorted
  • Throttle Valve Control Module circuit poor electrical connection

Code P0221 – Throttle Pedal Position Sensor/Switch ‘B’ Circuit

Possible causes

  • Throttle Position Sensor (TPS) harness is open or shorted
  • Throttle Position Sensor (TPS) circuit poor electrical connection
  • Faulty Throttle Position Sensor (TPS)
  • Fault Electric Throttle Control Actuator (or Throttle Body Motor)
  • Accelerator Pedal Position Sensor (APP)

Code P068A – ECM/PCM Power Relay De-Energized Performance – Too Early

Possible causes

  • Faulty Engine Control Module (ECM) relay
  • Faulty ECM
  • ECM harness is open or shorted
  • ECM circuit poor electrical connection

Code P2015 – Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1

Possible causes

  • Faulty Intake Manifold Runner Position Sensor/Switch
  • Intake Manifold Runner Position Sensor/Switch harness is open or shorted
  • Intake Manifold Runner Position Sensor/Switch circuit poor electrical connection

2011 Ford Fiesta

Hello, I have some sort of electrical issue with my 2011 Ford Fiesta battery light. Upon starting the vehicle around 15 to 30 seconds in the battery/charge light illuminates exactly like clockwork every start. Also when this occurs it pulls the engine slightly nothing major. And if the rear defogger is on it will kick off and wont come back on. I purchased this auto in March has 118,000 miles I am the second owner it is in very good condition as the previous owner was a female and she purchased it new. The Alternator is good and battery also under a load its at 13.8 volt and off its 12.6 volts. I am stumped any input or advice is very welcome. Thanks

The guys at fixya would have you do the following:

  • check the dash connection.
  • also if you have a multi-meter, check the voltage  as it could be a bad earth or the main fuse for the alternator is blown. on the main wire near the connection there might be a fuse, if the alternator fails it will blow this before it gets to the battery. called fusible link .

Sounds good, but looking at the wiring diagram you can clearly see there are no fusible links. Only one 450A Mega Fuse.

Saab 93

Left side window problem

I have this strange problem on Saab 93 year 2004 2.2 tid vector sport fully equipped.
Left side drivers side that is window is doing (or not doing) the following:
1.Once pressed down window goes down fine.
2.Once pressed up nope you need to hold it up all the way.
3.There is no pinch protection on that window,others work just fine.
4.All efforts to calibrate that side came out negative – all other windows and sun roof and side rear mirrors work fine.
5.Remotely on key I can open all windows and sun roof(except the left one),and consequently I can close all windows and sun roof plus rear door mirrors – EXCEPT the left side door window.
6.Nothing has changed on that door since I bought the car – no replacements of module or etc.I did changed battery on several occasions but calibration worked fine on all windows,since one day when it decided its gonna make me miserable.
I would appreciate if anyone had a similar problem and sorted that out.

Taking the fuse out 35 and harness at the door removing and all sort of methods up down wait were tried countless times…For no good.

Replacing the window motor and regulator assembly, in most cases, will take care of most window problems followed by the door module.

Diagnosing a window problem

There are a few things you can check. Check the glass guide seal (A) on both sides of the window. Make sure that no rubbish has become caught. Clean the seal if necessary. Look to see if the seal is damaged or creased. Therefore if the seal is damaged or creased it must be replaced.

window seal

Remove the door trim and check that the window motor and regulator are securely fastened without play. Adjust if necessary. Check that the the window is fastened securely an is not unsteady in the slider when raised and lowered. The window must be in contact with the rubber coated mountings.

Pinch Protection Programming

  1. Close the window
  2. Reset the pinch protection by removing and re-installing fuse F5 from the instrument panel electrical  center. The pinch protection for both door modules is now reset and both front windows can be reprogrammed.
  3. Start the car.
  4. Lower the window fully. Hold the button depressed during the entire operation.
  5. Raise the window fully. Hold the button up the entire operation. Wait for at least 1 second when the window is in the top position.
  6. Lower the window fully. Hold the button depressed during the entire operation.
  7. Raise the window fully. Hold the button up the entire operation. Wait for at least 1 second when the window is in the top position.
  8. An audible confirmation is heard when the calibration has been completed. In the event that there is no audible confirmation, repeat the procedure.

Dodge Ram 2500

Won’t come out of park

The shifter on my truck has been sticky since I bought it, but finally the other day I went to shift it into drive and the whole shifter fell. I was able to put it into drive by using the switch underneath and got it home. I replaced the whole shifter cable, and can move it now. But it won’t come out of park and the switch underneath seems to be jammed. Any suggestions as to what my issue could be? Or any solutions

Put it on jack stands. This will relieve some of the pressure on the parking pin in the transmission. The gear selector switch should move much easier.

Nissan Altima

Hello I have a 2002 Altima that was perfect, no problems. Then tried to start it and nothing, engine wouldn’t even turn over. However the dash light would blink then when I tried to jump it, it tried to start without the key in the ignition. Then a buddy was looking at it and had the negative cable off the post and tapped the post with the cable and the car again tried go start without the key… What could be the problem???

Somewhere there is a wire crossed or cable shorted. If there has been recent work done, start there. Follow the link and you will find a step by step diagnostic chart for no start conditions. Remember to start with a fully charged known good battery.

Battery Replacement

Before you disconnect the cable(s), first turn the ignition to the OFF position. This will prevent a draw on the battery which could cause arcing (electricity trying to ground itself to the body of a vehicle, just like a spark plug jumping the gap) and damaging components such as the alternator diodes.

When working on any electrical component in the vehicle, it is always a good idea to disconnect the negative battery cable. This will prevent potential damage to many sensitive electrical components such as the Engine Control Module (ECM), radio and alternator.

Disconnecting the negative battery cable first will also prevent accidentally grounding the positive terminal to the body of the vehicle when disconnecting the battery creating a short to ground.

Reconnect battery cables by installing the positive cable first. Then connect the negative cable. This will reduce the possibility for voltage spike to occur that can affect the operation of sensitive electronic components. Be sure to check that your lights, windshield wipers and other electrically operated safety components are working correctly. If your vehicle contains an electronically tuned radio don’t forget to also reset your radio stations and clock.

Dodge Durango

My Dodge started overheating of all a sudden a month ago. I put in a bottle of coolant and that worked. But today it overheated again and I had to put another bottle of coolant. What would cause the loss of coolant?

Loss of coolant

In most cases loss of coolant is caused from a leak in the cooling system. As a result here are typically two kinds of coolant leaks, external and internal. Coolant appearing on the ground underneath of the vehicle is an indication of an external coolant leak.. Internal coolant leaks are more difficult but usually accompanied by white exhaust smoke.  Once you have determined if your coolant is leaking internally or externally you can begin diagnosing the cause.

Above all do not use coolant additives that are claimed to improve engine cooling.


The required ethylene-glycol (antifreeze) and water mixture depends upon climate and vehicle operating conditions. The coolant performance of various mixtures follows:

Pure Water-Water can absorb more heat than a mixture of water and ethylene-glycol. This is for purpose of heat transfer only. Water also freezes at a higher temperature and allows corrosion.

100 percent Ethylene-Glycol-The corrosion inhibiting additives in ethylene-glycol need the presence of water to dissolve. Without water, additives form deposits in system. These act as insulation causing temperature to rise to as high as 149°C (300°F). This temperature is hot enough to melt plastic and soften solder. The increased temperature can result in engine detonation. In addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).

50/50 Ethylene-Glycol and Water-Is the recommended mixture, it provides protection against freezing to -37°C (-34°F). The antifreeze concentration must always be a minimum of 44 percent, year-round in all climates. Engine parts may be eroded by cavitation as a result if the percentage is lower. Maximum protection against freezing is provided with a 68 percent antifreeze concentration, which prevents freezing down to -67.7°C (-90°F). A higher percentage will freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because specific heat of antifreeze is lower than that of water.

Therefore make sure you do not put coolant directly into the radiator at full strength.

 KIA Soul

My brake lights do not work. I have changed bulbs fuses brake pedal switch. it is not getting a constant hot to the pedal switch only with key on.

Sounds like you have gotten into a good one. Lets see if I can’t help narrow this issue down a bit. I like to start approaching electrical problems first by looking over the electrical schematic for the problematic system. We will work with the Exterior Wiring Diagram provided below. It appears as though you need to check two fuses, the STOP LP FUSE and the IG1 FUSE. Also check the HAC RELAY and the STOP LAMP RELAY located behind the center of the dash). Beyond that you are looking at checking the wiring and connections.
