Known Problems

Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
