Problem with AC; Intermittent
Today I had a small problem. Last week I had the transmission drained and a new filter installed. When I got it back the AC did not work. Spent the weekend driving around in 88 degree temperature. Today I was taking it to the AC repairman, when suddenly it started working. Any thoughts? The car is a 1994 E320 wagon. I've had it for about 6 months. Thanks for any help.
