04 Nissan Sentra - Blowing Heat Only - 02/06/20 09:26 PM

I have a 2004 Nissan Sentra 1.8 that just now will not blow any cold air.
It is not warm , humid air you would expect when the AC is not working properly, it feels like heat from the heater.
Seems like it will not switch from heat to blended or cold air.
Any ideas what I should look for to diagnose the problem, or anybody have the same problem in the past?

Two of the first things to check is that your compressors is kicking on and that your blend door is functioning. Then you'll need to take it from there and others will chime in with more info.

Thanks SrDriver. That was the problem and was easily able to get blend door flipped back to cold position. Still need to find permanent fix, but this will work for now. Thanks!
