Driver's side wiper arm on my '93 Sidekick is not working
My wiper arm on my '93 Sidekick (JLX) is not working. I've gone to the wreckers and picked up a replacement arm but only found out that the arm wasn't the problem. The teeth on the wiper arm and motor both look fine. I'm afraid it's the motor i've to replace. Any idea of how to do this?

you need to check to make sure the "arm" is moving , some gm vehilce have a sealed wiper unit, but the alero should still have arms. turn wipers on and look down at the cowl vent and see if it appears to move. if it is the mounting post for the arm on the passenger side has PROBABLY stripped out the soft lead mount at the bottom of the wiper arm. make sure the wipers are "parked", then carefully try to wiggle the pass side back and forth (its normal motion...). if it moves you will need to pop the arm off(super careful here..) and the post that looks smooth must be cleaned out with a fine pick or equilalent, the post accually has splines all around to engage the wiper arm. put on the new arm.. presto.... wipers.
remove the arm from the pivot, lift the arm to permit the latch to be
pulled out to the holding position and remove the arm from the pivot
with a rocking motion.

Fig. 2: Mount the wiper blade/arm as shown-1994-96 Pick-ups
When installing the arms, the at-rest position of the blades
should be determined before pushing the arm onto the pivot. For Dakota
trucks, the tip of the driver's side blade should be 0.51-2.63 in.
(13-67mm) above the cowl panel and the passenger's side blade should be
0.94-3.06 in. (24-78mm) above the cowl panel. For 1989-93 Pick-ups and
Ramchargers, the driver's side blade should be 1.84 in. (47mm) above the
windshield weatherstripping at the heel of the blade; the passenger's
side blade should be 2.24 in. (57mm) above the weatherstripping. For
1994-96 Pick-ups, the wiper motor must be in the PARK position and the
wiper blade should be about 0.85 in. (22mm) from the upper edge of the
black-out areas at the base of the windshield.
You don't have to put the wipers in an upright position You can take the arms completely off. It's very easy to do, when you are looking at the base of the wiper arm, on the side closest to the windshield, at the base, there is a spring-loaded tab. Lift the arm on its hinge to where the arm is now pointing away from the windshield, pull the tab and the wiper arm will slide right off. Now you can access the linkage joints easily. Hope that helps!
Check wiper arm where it fits to the shaft the nut may have come loose! if so reset the arm to its normal resting place & retighten!
if its ok then its more likely that it has come off its pivot under the csuttle panel
it may need a new pivot
