Question about Cars & Trucks
I have a 2005 GMC Yukon Xl that all of the fuses are good and the interior controls seem to be working and the rear blower motor will not turn on. There is no power to it when the car is on and the ac on.
There's a rear hvac fuse 30amp that powers an auxillary blower motor processor controller. The controller has the resistor to regulate fan speed. The front and rear fan control both pass thru the front controller first then to the rear processor.
You may need a shop manual to be able to diagnose the problem.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

The best thing to do would be to remove the blower motor and use a set of jumper wires to connect it to a battery or battery charger. If it works, the problem is the blower resistor. They are a common problem with GM products

The compressor on the air conditioner in my 2000 GMC Yukon XL went out last summer. Had it and the whole line replaced at a local air conditioning shop last fall. Used it little before cold weather. Warm weather this spring and no cold air. We could hear the compressor trying to kick in. The shop told us that the control console was bad and had to be replaced. They told us the part was on back order and did not know if they would be abel to get one any time soon. We took the Yukon into the local GM dealership. They told us that the high side fitting was bad and that the freon was very low and that they would have to deal with that first to check the system. Called back to the air conditioning shop and they said they had a console come in and they would put it in and check the high side fitting. I now have cold air and questions. Bought Yukon in 2005 used, had always had problem of not switching to cold air once the heater has been used. We were told changing the console should fix that. It has not changed. I feel like the console angle was a scam, that the system was just low on freon. Each shop was blaming the other for trying to scam me. And what can fix the heat to cold issue? If anyone has answers I would sure appreciate the knowledge.
