Most GM products have the o-tube located inside the evap metal line where the high side hose connects. Evacuate the freon, then disconnect the high side line. Look in the metal line coming out of the evaporator and there it is. These can require that you carefully screw a screw into the plastic part then use vise grips to remove. Usually, these are replaced along with the filter/dryer when recharging the system.
Try to back wash the heater core first if it doesnt work then its clogged up try to turn the heater on the front with the heater off for the back keep an eye on the temp guage if it goes up than normal then its clogged....
Fyi u have to run the engine for awhile with the heater fan on
dodge has dual blend door actuators on the air box. you have to pull the dash board assembly out to access the passenger side door actuator. it calls for 5.8 hours to do this job. you also have to evacuate and recharge the ac system.
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.
