Known Problems

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The passlock sensor in the ignition lock cylinder may fail causing an anti-theft system fault and a no start condition. Our technicians tell us that the ignition lock cylinder should be replace to correct this condition.

Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

The front window sash brackets may break causing the window to come off track. Our technicians tell us that new brackets are available and can be installed on the old window glass if it is not damaged.

Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

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

The ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.

The oxygen (O2) sensor may fail causing the engine to burn to much fuel and may cause the check engine (SES) light to illuminate.

The turn signal switch may fail causing the hazard/turn signal flasher to continue to click even when the turn signal switch is off. Replacing the faulty turn signal switch will commonly correct this condition.

It is common for the high pressure power steering rubber hoses to leak. Our technicians recommend replacing leaky rubber hoses to prevent the loss of power steering.

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

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

The spark plug wire rubber boots may get soaked with oil, causing a misfire or rough idle.

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
