When the heater only works on high, the most common problem is a blower motor resistor. The correct repair is to replace it with a new resistor.
Door lock mechanisms not operating properly. Doors may not lock/unlock.
Replacement of faulty door lock actuator required for proper operation.
The steering rack may fail causing a loss of power steering fluid as a result the steering may become hard to turn.
The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.
An intake manifold vacuum leak can develop from a variety of sources, often causing illumination of the Check Engine Light with codes P0171 & P0174 stored. Thorough diagnoses will be necessary to pinpoint the cause in order to make the correct repairs. A "smoke" machine is often used to isolate the cause of difficult to find vacuum leaks.
The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
On vehicles equipped with rear air springs, the air compressor may fail causing the rear suspension to sit low.

I've had an intermittent no-start condition on my 2000 Buick Park Ave. This started happening on occasion and was nerve racking. Took it to my local mechanic shop and he replaced the crankshaft position sensor which solved the problem. Found the problem with the sensor 'A'(18X24X) out of range. Code PO336-CKP. in the computer. Hope this info will help others who have this problem.
