Park Ave Blower

This a 1991 Buick Park Ave. When the AC is on the blower just stops working. I haven't worked on to many Buicks,, is this a stange one to me. I am hoping that some Buick Master Mind may know what the problem may be. :banghead:
Thanks guys:

Figure anything out yet? My '91 Park Ave. has had and presently does have this same problem. Check my recent thread for details.

You probably have melted connectors on the blower relay.

Jed Rule, you're right on target. There were actually two problems...for details, switch over to my original thread "91 Park Ave. - Blower Won't Work on HI Speed Setting."
