About a week ago I got in my car and switched the air on and it was not blowing cold. I just had the compressor changed in August. After running errands, stopping and turning car off at three different locations in a twenty to thirty minute span. The air suddenly started working again and had been fine ever since. This morning I turned the temperature dial to a little past the middle and when I went to lunch I turned the air on and it would not come on. I was only gone for seven minutes so as of now I don not know if the air will come back on yet until I get off work. Over the years I noticed this has happened briefly a couple of times and was not a consistent issue (I live in Louisiana so going from hot to cold is common). Please let me know what you think this could be. Thank you!

Try removing fuse 3 and 21 with key on for sixty seconds then reinstall. It may reset air mix motor if not have that checked out it may be bad.

Thanks! On the way home from work about five minutes into my ride home the air started working fine again. I turned it off for a few minutes then back on and it still ran fine. It is supposed to be cool in the morning though so the problem happened changing my air from the heat back to air conditioning. I will let you know if removing those fuses help.
