After taking my 87' Deville for a drive, I noticed the A/C Fan would not change speeds when changing the Temp or the High/Low on the Climate Control, and when i turned the climate control off the fan stayed on and blew out the heater vent. Then when i shut the car off > The fan still kept running! I pulled the bottom of the dash out and checked all the relays and the BCM but everything checked ok, so i opened the hood and unplugged the Blower Motor, Thats when I heard a "Click" Like a Relay, so i plugged the Blower Motor back in and now it all works just fine. Now i have to find that Relay thats sticking > it sounded like it was towards the drivers side in the engine compartment. I checked my manual but so far i haven't found it. Any ideas Katshot?
