1990 Cadillac Fleetwood
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.
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 have high resistance causing a rough running engine or stalling condition.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
Loss of Power Steering Fluid From Steering Gear Failure
The steering gear may fail causing a loss of power steering fluid as a result the steering may become hard to turn.
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.
High Pressure Power Steering Hose Can Leak Fluid
The high pressure power steering hose will commonly leak fluid; it should be replaced.
Wear In Outer Tie Rod Ends Can Cause Steering Problems
The outer tie rod ends on the steering linkage may wear causing excessive free play in the steering and uneven tire wear. If the worn tie rod ends are replaced, the wheel alignment should be checked and adjusted as necessary.
Alternator failure
The alternator may fail causing the battery to go dead or the engine to stall while driving.
Check engine light due to failed EGR valve or control solenoid
Power Window Not Working Due to Window Motor
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.
Engine Control Module (ECM) can fail
The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.
Engine Overheating Due to Water Pump Leak
The water pump may develop a coolant leak resulting in an engine overheating condition.
Fuel injectors can short-circuit
The fuel injectors may short out electrically causing a rough idle.
AC compressor may leak and make noise
The AC compressor may develop an abnormal noise or refrigerant leak, requiring replacement.
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.
Poor Ride/Handling Due to Worn Suspension Struts
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
ABS accumulater may fail
ABS light due to master cylinder assembly failure
The ABS master cylinder assembly may fail internally causing the ABS light to illuminate.
