A defective fuel pump check valve (which maintains fuel pressure in the system when the vehicle is not running) may lead to long cranking times or hard starting (sometimes with stalling). The fuel pump should be replaced. However, if these symptoms are accompanied by Check Engine Light illumination, there may be a problem with the engine coolant temperature (ECT) sensor.
The window glass lift plates tend to bend or break and cause the window glass to tilt and bind in the door. The lift plates can be replaced separately from the window regulator. In more severe cases, however, a new window regulator may also require replacement.
The fuel level sensors can wear out and cause erratic or inaccurate fuel gauge readings.
Software updates are available to address transmission issues. However, due to the age of these vehicles, mechanical failures are more likely to be causing transmission problems. If a mechanical failure is repaired or the transmission is replaced, it is important to make sure any software updates have been taken care of. Failure to do so could result in continuing transmission issues.
Faulty pressure transducers (sensors) or the evaporator temperature sensor may cause the AC to stop functioning. The body control module (BCM) may lock up and create similar symptoms. Disconnect the battery for five seconds before resetting the BCM.
A worn AC belt idler pulley may cause the AC belt to roll over in the pulleys or come off completely.
The automatic transmission can develop problems like harsh shifting, shuddering between shifts, and a buzzing while in Reverse. Repairs for many of these problems are outlined in service bulletins and require removal and disassembly of the transmission.
When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.
Failure to use the correct automatic transmission fluid and follow the maintenance schedule can result in shifting problems.
Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.
A defective vehicle speed sensor can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors are also susceptible to corrosion, which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.
