2001 Cadillac Deville DTS No Climate Control Fan? It's Frigin Hot & No A/C..Help :-(


We just picked up our 2nd Cadillac(1st was a 2005 CTS-V) a 2001 Cadillac Deville DTS....It's a very nice family cruiser, and we love it.....BUT a couple of days ago the Blower Motor Fan just stopped working. I press the fan speed up and down hoping it will magically work but nothing...

I had a similar problem with my BMW M5, where the Blower was stuck on one speed. It turned out to be the "Blower motor resistor". Does Cadillac have a similar resistor?

Thanks and this forum is great!

It is integral to the blower motor.

No. Not for your year/model.

GM uses slightly more modern PWM technology to control various system functions.

Look at this link (scroll down a little to get to your year/model) and report the Diagnostic Trouble Codes display ("B" codes are what we need);

I replaced the climate control, but the problem wasn't solved :) Next I'm going to try the Blower Motor Control Module....

I have a feeling that this might be a common problem, I'll keep everyone posted...

Just got the Blower Motor Control Processor, but I can't figure out where it goes?

Does anyone know?

Thanks!

I believe it's the black box on the side of the blower motor housing.

Yes, it's a little black box with a heat sink on it...But where is the Blower motor?

Thanks :)

Remove the under dash closeout panel (if there still is one) under the glove box, pull the passenger left foot carpeted kick panel, and roll back the floor carpet. The blower motor is in the HVAC stack in front of the console and radio head unit area.

You may want to subscribe your car for 3 years to www.alldatadiy.com. The entire GM Manual is there plus a whole lot of other good info. Chilton's and Haynes are far too generic for this job.

I already tryed replacing the A/C Module also, guessing it's the blower motor?

Check for 12 volts between the purple and black wires on the blower motor connector with the blower motor fan commanded to turn on. If it's there and the fan ain't running you got a bad blower fan... common problem.

my ac quit once, and it was a fuse that blew that ran the fan under the hood.
