a/c blower stays on high, will not shut off!

I believe the problem is the relay but I cant seem to find it? I had to pull the fuse. Does anyone know where the high blower relay is on my 99 Grand prix GT? Please help.

sounds like your blower control module is bad. it is a flat circuit board that has a quick disconnect plug. it is located at the top of the blower. take the blower out and it will be against the firewall. if it is bad it will look burnt.

Thanks for the help. It looks like the module/resister has the relay built on to it. The dealer only charged about $24 for the part.
