turn signal 2008 Ford FusionI have a 2008 Ford Fusion SEL 3.0L V6. 5 days ago my Left Rear Turn Signal went out. I noticed this because my blinker was flashing rapidly and on the dash display said to check LR Turn Lamp. Now today my Right Rear Turn Signal started doing the same thing. I decided it was time to try to fix the issue. I checked the exterior light fuses and nothing was blown. I bought 2 replacement bulbs, but my rear turn signals still were not working after being replaced. In the process of seeing if the new bulbs worked I noticed that my brake lights were not operating as well. My 3rd brake light in the rear window works though. Also when I turn my hazard lights on the two back hazards are not working. But when I turn my head lights on the rear lights that share the brake light bulbs get power. Just to be on the safe side I checked all of the fuses in my SJB below the steering column and everything was OK. I went ahead and replaced my brake light switch above the break petal and still nothing. I have a repair guide for my Fusion and found that the wires coming from the SJB to the Rear Turn/Stop/Park lights are the Violet/Orange and Grey/Brown. I checked the wires in the trunk and everything looked fine and also checked the wires on the connector going into the SJB and everything appeared fine. I couldn’t get a real good look at the wires on the SJB side being that they are behind the dash. I found that my contortion skills, trying to get a good look at the connectors and wires on the SJB side, were not the best .

At this point I am thinking it is a wiring issue or a SJB issue. Any help on solving this crazy issue is much appreciated. My troubleshooting steps are below in a easier format to read.

Turn Signal Issue

Both Rear Brake Lights, Turn Signals, and Hazard Lights not working.
Both Front Brake Lights, Turn Signals, and Hazard Lights are working.

TROUBLESHOOTING

1. Checked all fuses in SJB located under the steering column in the interior of the car. Also checked 60 amp power fuses in fuse box in engine compartment that go to SJB.
2. Replaced Turn Signal Bulbs.
3. Replaced Brake Light Switch located above brake pedal.
4. Checked wiring diagram and found that wires in the trunk appeared fine.
5. Checked wires and connector, as best as I could, under dash going into SJB and everything appeared fine.
6. Re seated connectors going into SJB.
7. Threw my hands up and Screamed……..


RESPONSE

Since your third brake light is functional it tells me that the brake pedal switch is operational. Also the third brake light uses the same ground so i wouldn’t suspect a loss of ground connection either. The turn signal bulb and brake light bulb are the same. This is also true of the hazard.

I would check for battery voltage coming from the brake switch on wire color VIO/WHT and make sure it gets to the SJB(SMART JUNCTION BOX).  If that checks out good, then Check for battery voltage leaving the SJB on PIN 11 and PIN 7. If that checks good, then check the wires at the brake socket on the GRN/BRN and VIO/ORG. If that check out good, then the bulbs are the issue.

A quick check would be to have someone hold the brake pedal down or use a tool.I use this tool often myself when no one is around to assist.

Check with a multi-meter for power and ground at the bulb socket for the turn signal. Many times the incorrect bulb can cause and issue.

1999 Ford Explorercar will rev up through gears till top gear then it starts missing and breaking down. click down  a gear and revs normal


RESPONSE

Sounds like an issue with the transmission possibly. Maybe the lock up converter is sticking. I would suggest trying an inexpensive product called “Shudder Fix”

1998 Ford F150I was going up my drive way. I got on the gas and my truck stalled on me for the first time. I put it in park and it started right back up. I am curious what caused this any ideas?


RESPONSE

Hard to say. Could be a glitch. Some moisture in the fuel. Loose wire somewhere. Vacuum leak. Sticking IAC – Idle Air Control.

At this point there is not much you can do. If the check engine light came on, you could check the codes. Other than that you will need to drive it until it gets worse or repeats itself more often in order to diagnose it.

Drain Tube Evaporator core housingAir conditioning works great, but in the humidity (florida) my carpet gets very wet only on the passenger side of my 1999 Ford Taurus. Not due to rain, have checked all window seals good. was told it could possibly be a drain tube plugged up. possible? Where exactly on firewall is it located? thanks


RESPONSE

There is a drain tube that does get clogged. It is at the bottom of the Evaporator Core housing. This is also the same location as the heater core housing.  Look below the heater core hoses at the firewall. That is the evaporator core housing. Look at and around the bottom of the housing. Simply prob the end of the tube with a pencil or screwdriver to unplug the drain tube.

Example location:

2002 Ford F150Changed the fan clutch. Should it be really loud all the time it’s nothing like before and really bad gas mileage


RESPONSE

It may may a normal fan noise but should not sound like it is hitting something.

Bad fuel mileage may be from something else. Start with pulling the engine trouble codes.

2001 Ford F1502001 ford F-150 4.6 misses after it warms up a little. runs smoothly while cold.


RESPONSE

When the engine is first started(cold) the computer uses preset parameters to operate the engine until it reaches normal operating temperature(warms up). At this point it moves from using the preset parameters to using the signals from the engine sensors.

The first thing to check would be any trouble codes that might be stored.

2003 Ford TarusThe trans-axle light is on and blinking. But in park sometimes the car will sputter like its going to shut down but then recovers. When shifting into reverse its fine but when i shift to drive the car slams into gear so hard the car jumps and no matter how hard you hit the gas it only gets up to speed slowly.


RESPONSE

  1. Check for any engine and transmission codes present
  2. Check the transmission fluid level
  3. Check for vacuum leaks

If the engine rpms are high and the car isn’t moving yet the fluid level is full but the color is dark or burnt, you are looking at a transmission rebuild.

2003 Ford EscapeI have already changed battery and alternator why wont my car charge? It is a 2003 Ford Escape


RESPONSE

There are several reasons why your car won’t charge:

  1. Faulty “NEW” alternator – How to test an Alternator
  2. Faulty “NEW” battery
  3. Bad connections or corrosion
  4. Blown Fuse – fuse B, 120 amp or Fuse 11, 15 amp
  5. Bad wiring – Wiring Harness

The charging system consists of the following components:

  • generator
  • integral voltage regulator

The generator maximum output provides 110 amps.

Charging System

The charging system is a negative ground system consisting of the following:

  • generator
  • PCM (2.0L Zetec)
  • internal voltage regulator
  • charging system warning indicator
  • battery
  • circuitry and cables

The generator is belt-driven by the engine accessory drive system.

Battery

The battery is a 12 volt direct current source connected in a negative ground system. The battery case is sealed and includes two vent holes to release gases. The battery has three major functions:

  • engine cranking power source
  • voltage stabilizer for the electrical system
  • temporary power when electrical loads exceed the generator output current

2005 Ford Ranger 4x4My 2005 ford ranger supercab 4×4 doesn’t want to shift into second gear ,it shifts alright first ,third,fourth and OD.It is a manual transmission.


RESPONSE

If it shifts OK when the engine isn’t running then the most likely problem is the clutch system. Most common would be the hydraulic clutch slave/master cylinder assembly. I recommend replacing the entire unit and using a factory ford assembly. They come pre-bled and saves time trying to bleed air from the system.

If it doesn’t want to shift when the engine isn’t running, the synchronizer is worn/damaged internal in the transmission.

Clutch

The primary function of the clutch system is to connect and disconnect engine power to the transmission upon driver command.

The clutch control system disengages the clutch when the clutch pedal is depressed and engages the clutch when the clutch pedal is released. When the clutch pedal is depressed, it pushes the clutch master cylinder plunger, which transmits hydraulic pressure to the clutch slave cylinder. The clutch slave cylinder engages and compresses the clutch pressure plate diaphragm spring, releasing the pressure on the clutch disc, which in turn disengages the transmission from the engine.

  • The clutch is a single-plate, dry friction clutch disc with a self-adjusting, diaphragm-style spring clutch pressure plate.
  • The clutch operating mechanism consists of a clutch slave cylinder with an integral release bearing.
  • A pilot bearing supports the end of the input shaft. The bearing does not require lubrication unless the clutch system is serviced.

Manual Transmission and Clutch

The manual transmission has a tag to identify assemblies for repair purposes. For additional information, refer to Section 308-03 for the transmission tag information.

The purpose of the clutch is to connect and disconnect a manually operated transmission, and the remainder of the driveline system, from the engine. This allows starting and stopping the vehicle, shifting and changing speeds that correspond to the engine speed through gear reductions.

The clutch operating mechanism consists of:

  • Flywheel (6375)
  • Clutch disc (7550)
  • Clutch pressure plate (7563)
  • Clutch release hub and bearing (7A508)
  • Clutch master cylinder (7A543)
  • Clutch slave cylinder (7A508)
  • Clutch reservoir (7K500)

The clutch master cylinder transmits fluid pressure to the clutch slave cylinder, which in turn moves the clutch release hub and bearing. Check this first if it doesn’t want to shift. The clutch hydraulic system uses brake fluid and has a separate reservoir. The clutch is a single plate, dry-friction disc with a diaphragm-style spring pressure plate. The clutch disc has frictional material where it contacts the flywheel and the clutch pressure plate. the clutch pressure plate applies pressure to the clutch disc, holding it tightly against the surface of the flywheel.

In the engaged position, the clutch pressure plate diaphragm spring holds the clutch pressure plate against the clutch disc, so that the engine torque is transmitted to the input shaft. When the clutch is depressed, movement is transmitted through the clutch hydraulic system, which actuates the clutch release hub and bearing. The clutch release hub and bearing pushes on the spring center towards the flywheel. The diaphragm spring pivots at the fulcrum, relieving the load on the clutch pressure plate. Steel spring straps riveted in the clutch pressure plate cover pull the clutch pressure plate from the clutch disc, disengaging the engine torque from the transmission.
