Auxiliary air pumps are very unusual for this vehicle. Did you mean blower motor?

General Motors Driving Cycle just make sure you have no codes and your chk eng light is not on,drove me nuts for weeks nothing would set so i got my own scanner and seen that the coolant was only reaching 140F so i changed the thermostat and the next ride everything set so look for the little things that might be wrong. http://www.obdii.com/drivecycle.html

It sounds like a bad connection or a broken wire somewhere. Check to make sure that all connections to the battery, engine, and chassis grounds are clean and tight.

It is not the ABS causing this problem.

the actuator for the hub locking is faulty and not engaging the hub correctly. There may be badly worn teeth to engage or broken parts in the hub.
Have an accredited drive line shop check it out.

Wow, big problem. This may not help because you may have already checked it, but have you checked the ignition coil? If you have, then ignore this. Good luck.

If this is a cable driven speedo, need to lubricate cable.

Gabe maybe right. This transmission has several electrically activated servos that tell the transmission when to shift , according to how fast the vehicle is moving. At best, you may just need to replace a servo, at worst, you may need a rebuild.
Since the vehicle is 15 years old my guess would be the latter, not having any first hand knowledge of what else may be going on.

A more detailed problem description would yield you a more specific/helpful answer.

I'd suspect dirty fuel injectors if your tune-up is recent. A clean fuel injector sprays a fuel pattern into the fuel delivery system. A dirty injector will only squirt the fuel thereby causing an improper spray pattern causing a misfire at first then worsening if ignored.

check ignition fuse and coil. if the plugs are not delivering fire, that could be the problem. best luck to you!

Wiper arms have a hole at the end that fits over the wiper drive shaft and is secured by a nut. If the nut is loose the arm will not move predictably or will not move at all when the motor is on. You will also be able to move it by hand. This nut and shaft are covered by a piece of trim that can be pried up. It pries from the edge opposite of the wiper arm.
