The steering rack may fail causing a loss of power steering fluid as a result the steering may become hard to turn.

I'll turn up the temp on the dual control to get heat, and/or the defroster to blow warmer air. All I get is cool air that makes for an uncomfortable ride and slower defrost. I did replace the blower motor in the summer, could this have caused the problem by not hooking something up correctly?

RUSTED BRAKE TUBES AT THE ABS UNIT.
REPLACE THE STEEL (Lines) TUBES (4) AND BLEED SYSTEM.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

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.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

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 EGR tube may develop an engine vacuum leak causing the engine to run lean. The Check Engine Light may or may not illuminate.

Fan has a loud roar as if there might be a blockage of air flow.

The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)

The ABS master cylinder assembly may fail internally causing the ABS light to illuminate.

troubleshooting: pried off the plastic cover behind the door handle (start at the hinge side), removed single screw and then starting at the bottom pulled off the door covering (It is held in with plastic snaps), found 12v going into the door module and deduced the module was the problem; found one on ebay motors ...
