I have a 1993 DeVille with a continuously running blower fan. I was told that the fan relay was under the hood. Pulled all the relays and the fan still continued to run. If I pull the AC maxey under the hood, the fan stops. Can anyone tell me if this is the correct location for the fan motor relay?
Thanks

Blower fan running on is almost always the blower module failure. Sits on top of the plenum, near the blower motor. There is no relay..
Temp 'fix' is to pull the connector off the blower motor.

I've got good used modules for $38 postpaid.

YUP - Harry is correct - you need to replace the blower module -

the 1993 was the last year the separate blower module was used -
1994 and newer it is built into the blower motor -

Thanks! I have pulled the module. Do you need the GM number to identify? Mine has 1 pin on the small plug and 3 pins on the large plug.

I am interested in one of your modules. How do I get your co tact info?
