In response to SSR2 - the temperature was above 50F yesterday when I tried running the AC. I am not sure how much above 50F it was but the temp outside could possibly be the cause of my lack of AC.

Today will be about 68F so the AC should kick in today. I have to drive about 2 hours so I'll give an update at the end of the day to let you guys know if the problem is sensor-related.

Thanks!
