I checked the fuse and it is still good. I've checked as much as I know to check and have narrowed it down to the multi function switch. You mentioned cleaning the switch. Can you tell me how to do that? It sounds like it would be worth the time before I spend $200 a new switch.

I found this in the Grand Am forum but it should be damn close if not right on for us too...
The fix for this is easy and free. The problem is caused by contaminated grease which has bridged contacts of the multifunction switch. This cause a short circuit which cause the hazard flasher to cycle. You need a #25 torx and a # 10 torx. Remove the 3 #25 torx screws which hold plastic surrounding the steering column. Remove the plastic. Remove the 25 torxmulti function switch. Detatch the wiring connectors. Remove the multifunction switch. Use the #10 torx to remove all the #10 torx screws. Remove the cover and clean the grease off the contacts and copper switch plate.You will notice grease has bridged the some of the slots in switch plate. Clean it up and regrease. reverse steps to reinstall. Notice the metal peice protruding from the multi function as it facing you. This is the turn signal reset switch. When you turn this is what resets the turn signal when the wheels straighten. This needs to be pushed in so no more than 1/8 " is protruding. If you dont do this before reinstalling your horn may go off when ever you move the steering wheel after reinstallation. This whole job should take 20- 45 minutes based on your mechanical apptitude.
Regrease very lightly so as not to create the same problem again. Not sure if this will fix your problem but it's worth the few minutes of time. Let us know if it works or doesn't. I've only done this on switches that can't stop clicking. Good luck!
