- 2004 Mustang GT 4.6L manual transmission
I am having a unique problem with my AC and am running into dead ends. I recently had the AC compressor and everything else that goes along with that replaced because that was broken, so the car blows nice cold AC but on longer drives air will stop blowing out of the vents. I have replaced the AC blower motor and resistor and still experience the same issue.
On longer drives, around 40+ minutes I will turn the AC down both temperature wise and speed wise because the inside of the car cools down. Eventually I go to turn it back up because it starts to get warm but the air will not blow out of the vents. It sort of seeps out and it's still cold, everything sounds normal, when I go to maximum AC it sounds all good and if I turn from max AC to normal, floor, etc... I can hear what sounds like the vent door/blend door opening/closing but still no air out of the vents.
If I turn the AC off while driving for an extended period of time it will start to work again or if I turn the car off then back on it will work again. I started to play with it and noticed on maximum AC it will slowly start to reduce the amount of pressure it is blowing as the drive goes on.
I really don't know what the issue could be seeing as to how the blower motor, resistor, and compressor are brand new. FYI this issue was present before any of the new parts were installed.
Hopefully someone here has dealt with something similar and can point me in the right direction.
