Komodoman113 Posted January 29, 2004 Report Share Posted January 29, 2004 This is my first Cadillac and I must say that I have enjoyed this vehicle since I do about 55,000 km a year. The ride is great! However, I am getting quite a bit of noise which to me sounds electrical coming from behind the glove compartment. When I use my signals, it matches time. When the car is warming up, it makes funny sounds. Not sure what this is as I am not gifted in the mechanics area. I would be very grateful if someone could give me their thoughts on this so when I got to get it fixed I can narrow down the issue for the mechanics.

careldo Posted January 29, 2004 Report Share Posted January 29, 2004 the heater fan i beleive is located somewhere behind there one possibility is that the fan maybe is starting to go wacko or some debris has gotten in from the outside and the fan now is hitting it --just my 2 cents careldo Link to comment Share on other sites More sharing options...
EJPut Posted January 29, 2004 Report Share Posted January 29, 2004 Could be your PCM (Powertrain control module). It is located behind the glove box on the firewall. Link to comment Share on other sites More sharing options...
careldo Posted January 29, 2004 Report Share Posted January 29, 2004 the PCM is a solid state device with no electromechanical parts so i doubt it would make funny noises - relays on the other hand can are. careldo Link to comment Share on other sites More sharing options...

leadfoot Posted January 30, 2004 Report Share Posted January 30, 2004 I've fixed many Chevrolet Blazers with this condition by installing a new turn signal switch. The contact inside the switch short out which cause the signal flasher to activate, but it doesn't complete any lamp circuits, so no lights flash.
