I have a strange one that I am hoping someone has run into. The A/C in my Cougar seems to be fine. Compressor operates (doesn't cycle) and the pressure is within limits. But the weird part is that the left two vents/ducts blow warmer air then the right two vents/ducts do. Is there some type of blend door that could be causing this? After you drive it for a while on MAX A/C is seem to level out, but you can definitely feel a difference with just your hand in the temperature. Is there a vaccuum line that could be bad or leaking causing this? Thanks.
