1992 Cadillac Coupe Deville blower fan runs all the time

Fan runs even with key out of the ignition. I have removed A/C fuse and blower turns off. Re-installed fuse , removed all the relays under the fuse box on the fire wall and removed all the relays on the fusebox behind glove box along with every control module behind glove box I could see,and the fan still runs. Where is the fan control module or high speed fan relay located?

AC blower will not turn off on 1999 Cadillac Deville?


Are you sure it is the AC blower? a lot of modern cars have a temperature controlled radiator fan, this can run when the engine is very hot , even when the keys are removed. It is a safety feature to protect your engine.

88 cadillac deville, ac blower fan wont shut off, even when car is turned off and key removed. I tried disconnecting the battery to reset the system but it still runs when battery reconnected. Also, car...


Ralph,
Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.
Charlie
PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.

Heater fan will not switch off when car is running or not. Had to pull heater fuse to stop.


It has a blower control module instead of a resistor mounted in the box next to the blower motor. The blower control module is bad

Coolant fans on a 92 coupe deville


You checked the fuses, that's a good place to start. Usually electric fans are powered up using a relay. It's likely that each fan has it's own individual relay so it's strange that niether fan works. Is the engine overheating? Try turning on the air conditioner after starting the engine. One of the two fans should definitely turn on immediately after switching on the A/C. If so, then the other fan, which would be controled by the temp sensor circuit, might be bad. Before replacing anything you may want to check the temperature sensor is working properly. The relay(s) are probably located in the engine compartment usually near the firewall. Hope this is helpful, if so, please remember to rate my response. Thanks.
