Until I find the fix, this will allow you to remove the key. Disconnect the negative clamp on the battery. Remove the key, and reconnect the battery. Weird, huh ? But it works !

Maybe I can help, I just saw a picture of it, but couldn't find location.From its look, though, it wouldn't be exposed to outside, so its got to be under the dash, and GM is prone to putting pcm's on the passenger side, behind the glove box...but wait, there's more: this is one of the smallest engine computers I have seen. It's a dark gray square, about 4 inches by 4 inches, flat on one side, and about 2 inches in height. One end of the little box, probably facing down in the car, is where the two large bulks of connectors plug in. Yes, two connectors, one above the other, each with two rows of pins- (in total there must be more than a hundred pins), and the two long connectors are about 2 inches high and 4 inches long in total, almost as big as the end they plug into. So if you looking up under the dash, you may not see the box, but you can't miss the large block of electrical wires going to the two thin but wide connectors plugging into the computer. Well, good hunting, Angel. If this helped, please let me know. If it didn't help, you can let me know that, too. Good day.

If it's out try to turn the gear one way then the other,if it spins easily in either direction ,the "bendix" spring is broken,the starter will hit the flywheel but disengage right away.If it doesn't hit the ring gear at all,look at the teeth on the flywheel,also when you put it back in be sure to tighten the bolts evenly,.

that's the way they work, the ac takes the moisture out of the air so it doesn't fog up the window

Its normal for the compressor to run any time the control is in defrost mode.The compressor runs to dry the air blowing onto the windshield.Check your owners manual for details.

Yep through the dimmer switch itself. The dimmer switch is either bad or the pigatail to the dimmer switch is bad.
