V8 two wheel drive automatic 50,000 miles. It started with intermittent stoppage and finally the front A/C will not blow air at all while the rear A/C will continue to blow air and the air is cold. It is an intermittent issue on top of everything else. There are times when the front unit will turn on just as normal as it should and then other times, it will not turn on at all, while at other times, it will turn on only after the rear unit has been on for awhile.
There is no rhyme or reason as to what makes the front unit decide to come on. I have tried turning the control to reflect the front unit blow air from the top and bottom and I can feel a very slight bit of air flowing from the air vents. When this happens, sometimes the full front unit will kick on and other times it just runs with the very slight air. Other times, the front unit will not blow any air even with the control knob in that position. Yesterday, the front unit worked perfectly as if there was never an issue and this morning nothing.
If it is the blower, I do not know. It seems to me like a vacuum issue as I can hear something in the air vents trying to open or close. Maybe that is what it is? I just do not know but other times, I cannot hear the same sound. Did I help at all?
Okay, When the air does blow from the front, it blows exactly where it is supposed to. But when it does not blow, it does not blow from any of the front vents. So when it does kick on and I have the control set to AC, it blows from the proper AC vents. Does that make sense?
Additionally I am speaking about the AC, not the heater just in case that makes a difference.
It is very frustrating.
have the same problem?
