1990 Cadillac Eldorado Problems
Car Won't Start and Security Light is On
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.
Trunk Lid Won't Close Due to Trunk Pull Down Switch Failure
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.
Power seat operation erratic
Rear of Vehicle May Ride to High or Low
The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.
The Head lights May Stop Working
The head light switch may fail causing the head lights to become inoperative.
AC Not Cold Due to Refrigerant Leak and/or Pressure Sensor Fault
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.
AC Compessor May Fail
The AC compressor may develop an abnormal noise or refrigerant leak, requiring replacement.
High Pressure Power Steering Hose Can Leak Fluid
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
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.
Transmission Fluid Leak From Cooler Line
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.
Coolant Leak & Engine Overheating
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
Performance Issues Due to Faulty ECM Grounds at Front of Engine
The engine control module (ECM) electrical grounds on the front of the engine block may develop high resistance causing engine performance issues.
Fuel injectors can short-circuit
The fuel injectors may short out electrically causing a round idle condition.
EGR control solenoild or valve may fail
Smog Check Failure Due to Excessive Carbon Buildup
Excessive carbon build up in the engine combustion chambers may be the cause of a smog check failure due to excess NOx emissions. A "top engine" decoarbonization cleaning procedure will commonly correct this concern.
