The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

The ignition coil housing may fail causing an engine misfire on one or more cylinders.

The automatic transmission shifter may fail causing the ignition key to become stuck in the ignition lock cylinder.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

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.

The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

A weak battery or a burned out brake light bulb may cause the ABS light to illuminate.

The instrument panel and switch backlighting may fail due to a faulty dimmer control module. A failed module will require replacement.

The timing chain tensioner and guides are prone to wear and may develop an abnormal noise, requiring replacement.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The 2.3L 4 cylinder engine can be prone to head gasket failure. This can result in coolant loss and engine overheating.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
