Is this a limited-slip differential? You might try a rear axle fluid change-don't forget to get limited-slip additive(or a fluid that has it blended in)

need more info---did you have brakes worked on, did it happen all of a sudden???

You need the tail lamp assembly,

Replace bulb

It's like you are losing the fluid someshere. Check for leaks in four cooling system.

On the rear of the motor,on the drivers side,right behind the ignition coil,by the distributor.

follow the wiring wherit passes through from the hatch to body of vehicle sometimes they pinch or corode and break, this sounds like a broken wire to me,

You probably need to get it vaccumed because having too much coolent can make it not work at all. I had a 97' Suburban and the vent wouldnt open, in the dash

well it sounds like you have too much freon and or oil in the system you need to have it evacuated and vacumed down and fill with exactally what it calls for and you need to also check the action of the fan make sure enough air is comming through the front of the car

check the pressure switch on the receiver drier (the tin can looking part near the fire wall)
