SOURCE: 2004 suburban rear a/c only blows hot air

ase mechanic:
there are separate actuators for the blend doors. one for heat and one for cool. they work opposite and in conjuction with each other, if that makes any sense. ones open, ones close, for each different climate. sounds like the the cold one isn't opening in the rear.

SOURCE: Rear a/c not blowing cold, front works fine.

probably the same problem as the '99. you probably lost too much coolant. charge with dye and check for leaks, (these things lose refrigerant normally, so you may not have a bonafide leak but check anyway) change the accumulator as a matter of course. evac the system and make sure you lose no vac over the course of 5 to 10 min. recharge the system for the proper weight (which is on the accum sticker) if you need detailed instructions let me know.

SOURCE: 1998 gmc suburban ac blows cold in rear but not front

no its a bit difficult,another problem could be venturi/restrictor in the entrance to the interior rad for the AC ,if the back one is working then so should the front one ,your man is right it could be a trampilla ,sorry forgot the word in english ,been living in spain too long but this is the vacumn operated valve ,could have a split vac pipe as well that operates the trampilla

Why 1995 gmc vandura only blow hot air while driving but sitting still cold air


Low coolant level.... restriction in heater core or vacuum problem with hot/cold blend door would be what to look at. Worst case scenerio would be headgasket issue but unlikely

To check the rear expansion valve, see if the a/c lines are different temperatures. One line to the rear evaporator should be hot and the other cold if it is working.
Try to recailbrate the blend door actuator. Remove the HVAC module fuse. Wait at least 15 seconds. Replace it, turn the key on and wait 40 seconds

What causes the ac to blow cold in the rear but warm air in the front?


These vehicles came with 2 types of ac controls.
The vacuum control system uses vacuum to actuate the vents and ducting from hot to cold. A lot of times the HVAC vacuum line in the engine bay (black hard plastic) is either broken or disconnected from its vacuum source.
The electronic vent control: does everything at the control knob via vent actuators and the control panel itself. With this one it could be any of the components. You would have to locate them and verify operation by moving temp/vent selector.

good work, the clicking noise you hear is the blend door trying to move. this door is what controls the temp. the most common reason is the actuator motor is bad but sometimes the door hinge breaks, this hinge slides into actuator and is used to move the door. you will need to locate it on the heater box by locating the noise and then remove the actuator and see if the hinge is broken, i will try to enclose some picture to help you. good day, hope this helps.johnjohn2_142.jpgjohnjohn2_160.gif

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.

My Air Condition is only blowing hot air in the front, but cold in the rear. Could anyone give me a start in correcting this problem? Thanks


possible blend door actuator faulty, or a faulty blend door. This door switches from hot to cold vents. On expeditions equipped with rear AC front and rear AC have seperate actuators. Hopefully this helps!!
