I have the same problem, but I have found that it is one of the spring-loaded wheels that the serpentine belt rolls over. It's a $60 part and I heard its a pain to fix.

I plan to have mine fixed later this week or early next week. If I find a moment, I will post the results.

Sound like it may be a loose motor mount (or two) and the motor is shifting enough when in reverse that the inner side of drive axle is rubbing against it, an exhaust component, or something, or the flywheel or drive belt rubs against a plastic shielding, a broken wheel-bearing internal seal perhaps, is flopping around in there.
Could be a worn part in transmission like a bearing and something is rubbing inside of transmission.  I would not put stress on that by doing that often, after all reverse isn't as important but does come in handy once in a while. I really suspect that an axle is rubbing on a piece of plastic or is transmission.
Perhaps your brake pads are shifting and vibrating due to a different wear pattern or grinding a new and different spot on rotor - nothing very serious but put some spring clips on the caliper sliders next time you do the brakes and there is a glue to glue the brake pads in place to reduce vibration. and the caliper sliders may be worn and loose to allow this movement.
There is simply a shield behind the rotors that can rub on the rotors and is simply fixed by taking a screwdriver and making space between the rotor and the backing plate, as it is called.
Be careful if very rusty and not to push too hard on one side and make the other side closer or to bend it.

Well, i have the same model make and year, and I can tell you mine does the same thing. i have yet to narrow it down, however it has yet to do any damage to the vehicle, though I can easily see where it is unnerving and annoying. i know this is not a true fix, however there seems to not be much to this, several mechanics have told me its just something they do (that year) and not to worry unless it causes a problem. hope this helps!

Looking for easier way to change spark plugs on 94 corsica 3.1should i remove the coil pack or go under neath the car for the back 3


I just rencently finished woking on a 3.1 engine and can understand your problem. The coil pack should be mounted on a frame that is attached to the engine. If you located the mounting bolts for the frame and remove them the coil pack can be moved out of the way enough that you will have easier access to the plugs and you wont have to remove all the plug wires. It will still be a little tight a long extenstion on your socket will help with the mounting bolts for the coil pack frame. Hope this helps.

Cooling fan 94 corsica


Replacing the fan is a straight nut and bolt job.
The fan is going to be the expensive part.
I would suggest a local wrecking yard for the part.
