1990 Cadillac Eldorado Problems
RepairPal has identified the most common problems with the 1990 Cadillac Eldorado based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
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 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 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.
Problems with 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 key and ignition lock cylinder should be replaced to correct this condition.
The head light switch may fail causing the head lights to become inoperative.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
The fuel injectors may short out electrically causing a rough idle condition.
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.
