Two problems related to check engine light on have been reported for the 2004 Chrysler Town & Country. The most recently reported issues are listed below.
This vehicle turns off when driving and there is no power to the car at all, no brakes, steering, headlights and the car can not be restarted, you cant even unlock it too get out or get the windows down. The dash lights go out, check engine light cant be reset, fan and a/c controls never turn off if the car is running and dings and beeps went it wants to like its crying for help.
The 2004 Chrysler town and country check engine light came on and the engine was running rough, especially in idle. The odometer reading was 37,500, the vehicle was 3. 5 years. Old, and it has a 3. 8 liter engine. A Chrysler dealer ran a diagnostic check and determined that new spark plugs and wires were needed. Also, some computer codes may need to be reset. Cost would be $350. I bought the parts and installed them myself. I replaced many spark plugs in the old days and these were the worst looking plugs I have ever seen. The tips of the electrodes were severely rounded off on all 6 plugs. I owned Chrysler/Plymouth minivans since 1984 and only remember replacing spark plugs once, and probably @ a high mileage. Champion warrants their platinum plugs for 5 years. Chrysler's maintenance schedule says to replace spark plugs and wires @ "100,000 miles". Something must be wrong with this engine.
