Probably the fan power module. Expensive guess. they cost roughly $100.00 thru www.gmpartsdirect.com. Located at firewall underhood.

Mine recently failed due to low pressure switch on AC. Had a freon leak. AC would blow hot air, do yours work at all??
You can direct wire your fan motors to your battery to test motors.

Dont get side tracked. A pressure switch has nothing to do with fan operation, just air temperature. Good point tho to run a wire from the fan to the battery to rule out the fan itself, but my experience says a fan motor fails slowly over time and gets noisy or smells like burning wire just before it quits altogether.

used units pop up in ebay at around $30.

arent the same units used on the Allante and for that matter on most all Cadillacs of the era?

hint .. salvage yards .....
very easy to R&R

Yes, the same. In fact my 91 Allante has one from a 92 Seville. $20.00 at pick n pull!!
