Newest 1993 Buick Riviera Problem Reports
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 camshaft position sensor interrupter (magnet) on the camshaft sprocket may fall off causing the check engine (SES) to illuminate. If this fault occurs on high mileage vehicles our technicians recommend to also replace the timing chain at the same time.
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.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
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.
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 high pressure power steering hose will commonly leak fluid; it should be replaced.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
