Help! AC stops working after 20 min - Nissanhelp.com Forums
I have a 2007 Altima 2.5S... came across this very strange issue.
The AC air will stop blowing from the vents after 15-20 min of driving.
1) AC works perfectly fine in the beginning. Then gradually less and less air comes out from the vents.
2) The air is constantly cold... and what little air that comes out of the vents after it stops blowing is still very cold.
3) Turning the fan to max, I can hear the blower engage and blow air harder. But no air comes from the vents.
4) Turning OFF the A/C unit but leaving the fan on will start allowing air to come out of the vents. Air that comes out is cold.. seems like residual cold air.
5) After about 5-10 minutes, the AC can be started again and cold air still comes out.
The compressor is new, but this did not fix the issue. I know this model Altima does not have a typical blower motor resistor (which would be my good guess). I wish I could log into the nissanhelp forums but I cannot seem to register there completely. Any help would be much appreciated
