Failure of the rear transmission mounts is common.
The head light door actuators may fail causing the head lights to become stuck in the raised or lowered position.
The tail or brake lights may be dim due to a poor ground connection inside the light socket. Failed light sockets will require replacement.
The fuel injectors may short out electricity causing a rougher than normal idle.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
The hood and rear hatch supports may fail causing the hood or hatch fall back down after being raised to the open position. Replacement of failed supports is recommended.
The t-top models are prone to water leaks from the t-tops weather strip seals. Our technicians tell us that replacing the all of the t-top related weather strips will commonly correct most leaks. Care should be taken when removing and installing the t-tops in order to avoid damage to the weather strips.
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.
Problems with the anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The the key and ignition lock cylinder must be replaced to correct this condition.
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.
