Most reported 1992 Cadillac Eldorado problems
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 air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.
The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.
The head light switch may fail causing the head lights to become inoperative.
The vacuum release actuator for the parking brake may fail, preventing the parking brake from releasing automatically. Our technicians remind us that there is a mechanical release lever on the park brake ratchet you may use if the park brake does not release automatically. (Care should be taken when manually releasing the park brake!)
The high pressure power steering hose will commonly leak fluid; it should be replaced.
An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.
The fuel injectors may short out electrically causing a round idle condition.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
The engine control module (ECM) electrical grounds on the front of the engine block may develop high resistance causing engine performance issues.
