Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.

When front air is on rear heat always


If you have owners manual check that your climate control settings are as you expect them to be, if that makes sense. Some on Fixya do not realise they gave climate control , they think they have normal A/C and try to correct chimerical problems. Please check and repost

My gmc yukon 2000 slt rear ac blows hot air when i have ac . on and the front works fine .


I have a 2000 GMC Savana Van SLT with front and rear AC/Heat. My front would blow hot while the rear blew cold with AC on. It turned out to be low on Freon. It's hard to know if you have the right amount of freon installed because pressures vary depending on the ambient temperatures. So the best way is to remove all the freon then reinstall the recommended amount as listed on the evaporator housing near the firewall. This worked fine for me... works like new after installing the correct amount of freon.

When the ac is on the driver side vent blow only hot air and the passenger vent blow the cold ac air


Usually a sign of low freon or a blend door problem. If the system is full of freon, I would check the blend doors under the dash.

1997 gmc rear air conditioner is blowing hot


Could be a blockage in the lines to the rear unit.
Might be low on freon too. Or a blend door problem.
Can you check under the floor and see if one of the lines is cold ?

The blower blows air thru vent near glass-defrost vent and side-in door near window only. The freon has leaked out. Repair man says ac controller needs replacement. is this diagnosis correct.


If all of the freon has leaked out yes you will most likely need a new unit. The car is at that age so that does make sense that it will go.
The best thing to say is if no cold air is coming out then yes you need a new AC unit.


Good luck.

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.

1997 GMC Savans 35500, Rear Air only warm air


well what I see you have two problems with you A/C ..1- if the compressor is cycling very fast , the system is probably low in freon , this ban takes like 4lb of freon, now, 2-if we have the right amount of freon and the rear A/C don't work and all the vents are working fine back there for sure the problem is the expansion valve located close to the rear evaporator , that valve get stock open allowing to much refridgerant get in to the evaporator and no cooling at all ,in the back,... you can also have a bad low pressure switch located on the accumulator, making the compressor cycling very fast ..the first you have to do is check the pressures if they are OK , change the low pressure switch..then go to the second problem
