wcrowe Posted September 27, 2011 Report Share Posted September 27, 2011 Dear Forum I own a 1995 Cadillac Concours 4Dr Sedan with approximately 110,000 mi. One morning my wife was driving it and went to click on the AC. She noticed some smoke coming from the vent and the AC has not worked since. I clicked on my heater control and it to doesn't work. Before I take it to the dealer so they can attempt to charge me out of my wallet, can anybody give me an idea of what could be wrong and how to go about fixing it. Winter is coming fast and I don't want my wife and I to freeze. Thanks, wcrowe Link to comment Share on other sites More sharing options...
Ranger Posted September 28, 2011 Report Share Posted September 28, 2011 When you say the A/C and heater control doesn't work do you mean the compressor or the HVAC blower? I suspect the blower is bad. Does the blower connector on the firewall look burnt? Link to comment Share on other sites More sharing options...
KHE Posted September 28, 2011 Report Share Posted September 28, 2011 Sounds like the blower motor burned up. There is a lot if information in the archives on this. The motor has been redesigned and you must purchase the heat shield. There is no need to cut the housing to R&R the blower motor.

I suspect the blower is bad. Does the blower connector on the firewall look burnt? Thank you replying to my message. When I press the button on control panel to turn a/c on, there's no response. Same for heater and defroster etc! Nothing clicks or responds! How do find out if the A/C Compressor is not working? What is the HVAC blower and where are these componets located? Is this something I can find by looking under the hood? Link to comment Share on other sites More sharing options...

What function does the blower motor provide and where is it located under the hood? Is it something I can remove and replace myself? Does R&R mean remove and replace?

Ranger Posted October 1, 2011 Report Share Posted October 1, 2011 When you turn on the A/C or defrost, the compressor should run. Look at the clutch. If the center portion is spinning, the clutch is engaged and the compressor is running. If the center portion is not spinning, it is not engaged and the compressor is not running. The HVAC (Heating, Ventilation, Air Conditioning) blower is what blows air out of the vents to warm or cool the car. It is located on the firewall.

wcrowe Posted October 5, 2011 Author Report Share Posted October 5, 2011 Where is the blower for the A/C located on a 1995 Cadillac Concours Northstar Engine? Also, where is the A/C Compressor? Link to comment Share on other sites More sharing options...
Ranger Posted October 6, 2011 Report Share Posted October 6, 2011 Blower should be on the firewall. The compressor is lower right when looking over the passenger side fender. Link to comment Share on other sites More sharing options...

The blower motor/module is under the hood. There is a ton of info in the archives on replacing it. Yes - R&R means remove and replace.

Ranger Posted October 7, 2011 Report Share Posted October 7, 2011 What function does the blower motor provide It blows air over the heater core and/or evaporator to heat or cool the cabin. The air you feel coming out of the vents is a product of the blower (fan). Link to comment Share on other sites More sharing options...
