Chrysler PT Cruiser

I bought this car used. In less than a week, it started popping out of 3rd gear and making awful grinding noises from the transmission. Replaced the transmission.

Now, the fog lamps will not turn off (pulled the fuse), the interior lights will not turn on, the radio will not turn on, and the heater blower will not blow. Also, the power windows will not roll up or down. And the odometer flashes “no fuse” message. Checked for blown fuses and broken wires as best I could but, was unable to find any. It is quite possible that I missed or overlooked some of these. I am not familiar with this vehicle nor am I a mechanic. Please, help if possible. I didn’t pay very much for this car, but I don’t want to just throw away what money I have spent. – John

Electrical wiring problem

Generally when something will not turn off it is caused from a back feed or crossed wiring. Sometimes this can be from a sticking relay or damaged wiring. Other times a faulty switch or connecting the wiring harness wrong. Isolating each circuit should help narrow down the issue.

If I had to guess, I would think a power wire connection coming from or going to the fuse block. Most likely happened during transmission replacement. Double check your connections and wiring harness. Most of the fuses should be hot at all times. This means you should see battery voltage on both sides of the fuse.

  • Fog light fuses: 8
  • Interior lights fuses: 18,10, 2
  • Radio fuses: 18,13,2
  • Blower motor fuses: 7
  • Power windows fuses: none, one circuit breaker #2

Both headlights have stopped working

Headlights stopped working

If you know both were working then I would start with checking the fuses. If one was out and now both, start with replacing the headlights. There are 3 fuses to check. Check fuse #33, #17 and #12. Once you confirm the fuses are good, test for power and ground at the headlights.

Good power and ground means replace the headlamps. Still now power, check the multi-function switch. If that checks out then you are left with the Power module or wiring. I’ll supply you with a wiring diagram to help assist you with the problem.

Chrysler Pacifica

Is it possible for someone to have damaged my rear compression control arm? Because I have not hit anything for it to break in half the way it did.

Rear Suspension

Anything is possible. But it would be difficult for someone to cause a small enough amount of damage in order for it to break at a later date in time. It would be more likely that a pothole or parking block covered in snow would be the culprit. Maybe someone else was driving and mistakenly forgot to mention it.

The knuckle, camber link, compression link(8) and tension link are aluminum castings. Extra care needs to be taken when servicing these components. The wheel and tire mount at the end of the knuckle(7).

Unless you have recently had some work done, I do not think anything was done to it to cause it to break.

1999 Chrysler town and country

Stalls and dies

I have a 1999 Chrysler Town and Country lxi 3.8 engine. Every now and then when I come to a stop or slow down to turn my van stalls and dies. But when put in park or neutral it starts right back up with no problem. When I go to pull it into gear it stalls real quick and dies after several attempts it finally goes.

First thing to do would be to have the check engine light codes scanned. Any code stored may assist in directing you in the right direction. Post any code found below in the comments for further assistance.

Some possibilities if no codes are present may be but not limited to:

  • Dirty throttle body needs cleaned
  • Sticking or faulty IAC – Idle Air Control
  • Faulty TPS – Throttle Position Sensor
  • Faulty MAP – Manifold Absolute Prsseure Sensor
  • Vacuum leak

Engine Idle Speed

The TCM uses direct engine idle speed input and calculated engine idle speed (or target idle speed) input from the PCM over the CCD Bus. Target idle speed is compared against actual engine speed to determine the learned Throttle Position Sensor (TPS) value for closed-throttle idle.

Throttle Position Sensor

The Throttle Position Sensor (TPS) is used by the TCM to help determine shift points and shift quality. Additionally, the TPS output is spliced to the PCM for fuel control. The PCM provides a 5 volt supply and ground for the sensor. Target idle speed is compared against actual engine speed to determine the learned TPS value for closed throttle idle. This is done to correct for differences in system voltage and sensor tolerances.

If the TCM detects a faulty TPS signal, it provides continued operation of the transaxle by using the TPS value sent over the communications bus by the PCM.

2001 Chrysler Town and Country

Just had transmission rebuilt and the speedometer bounces when in gear. Or with foot on brake. It bounces more with lights and a/c heat blower on.

You may want to have the place that rebuilt your transmission take a second look. It would also be a good idea to have the TCM codes scanned.


The transmission output speed signal supplies distance pulses to the powertrain control module (PCM), which are used to calculate speed and mileage. A pinion factor is stored in the transmission control module (TCM) in order to provide the appropriate distance pulses for the vehicle. The pinion factor is programmed into the TCM at the assembly plant.

Using the following steps, the pinion factor can be checked and/or reset using the DRBIII®:

  • Select Transmission system, then Miscellaneous functions, then Pinion Factor. The DRBIII® will display the current tire size.
  • If the tire size is incorrect, depress the Enter key and then select the correct size.
  • Depress the Page Back key to exit the reset procedure.

Notes About Electronic Pinion Factor Features The nature of the electronic pinion factor requires that certain features must be taken into consideration.

  • If no pinion factor is stored in an installed TCM, the vehicle speedometer will not operate, engine speed will be limited to 2300 RPM, and catalyst damage may occur.
  • Selecting a wrong FDR or tire size will cause the speedometer to be inaccurate and will also cause any speed related features to operate improperly. Note: After replacing the TCM, you must reprogram pinion factor

2004 Chrysler Concorde

2004 Chrysler Concorde 2.7 recently developed code p0700 a general tranny code and p1779 solenoid switch in the l/r position. Did some looking and found a bare wire on either the speed input sensor or output sensor. Not sure what on. I fixed the problem and now the cruise control works as well. Could that have caused the tranny codes?


Chrysler Code P0700

Transmission Control System (Malfunction Indicator Lamp Request)

 Code P0700 Probable Causes

  1. Sensor or solenoid faulty
  2. Update control unit software – Check for the latest control unit update
  3. Powertrain or Engine Control Module faulty
  4. Transmission system malfunction

Generic Code P1779

Engine Torque Delivered to TCM Signal

Code P1779 Probable Causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
