Question about 1995 Cadillac DeVille
The display reads fine. all buttons function and show changes on display....however, no air blows. I don't know if I have a bad blower (checked fuses) or if there is a bigger problem. I've done lots of work on other cars, but this is my first caddy and I am unfamiliar with the auto climate control. Thanks
I just bought a 95 concorse and no blower on any of the system hot/A/C/defogger/defrost?????? can feel heat or cold but no fan/blower? HELP PLEASE
Hi and welcome to FixYa,
To my understanding, a 1995 Cadillac Concours' Heater-A/C blower does not use a conventional resistor type to control blower speed. Instead it uses a H-A/C Programmer (Control Module). This programmer is powered by a 10AMP fuse (#14) located at the trunk compartment fuse block. Other fuses to check would be:
Good luck and thank you for using FixYa.

On older Cadillacs, a few years older than yours, there are known failures where the blower usually just keeps blowing after the car is shut down. This is usually the blower control/controller unit, which, I think, sits on top of the AC/Heater exchanger unit under the passenger side of the dash. This is the 'box' that controls the auto temp control. Yours is the first time I've hear about the blower goes off when the car is shut down, but comes on some time later.
Ok, read in your owners manual closely about the Heater/AC system. I think there is a section that talks about how the blower will continue to correctly run after shutdown, under certain conditions. But I think it runs only for a couple of minutes or so in this mode. I don't know what these conditions are, but they are an attempt to 'dry out' the system, or some such thing. If you system is supposed to do this, then maybe it is working correctly.
In humid weather, with the AC running, with the car idling and stopped, does water come out of the bottom of the car? Normally, you should get condensation on the AC coil inside the car when running in hot humid weather, and this water comes out of a drain outside the car. If you car does not do this, then the drain is plugged. But, if you have had service done for the smell, they surely should have checked this.
Hope This Helps!!! Please Rate my Response!!! Thanks!!!
