A/c Problem
I just started using my A/C becuase its getting a little warmer. It blows out cold air for about 3-5 minutes. After it is just blowing regular air from the fan. After I turn my car off and on it works again for 3-5 minutes. Do I need to get freon refil? Or does my compressor need to be changed out?

No you most likely do not need a new compressor. Maybe a bit low on Freon or whatever they use. You should have it diagnosed correctly by a dealer before throwing parts at it

Last Fall I brought mine in and the workorder reads "Client sttes tht the A/C goes from cool air to warm air. also has a strange musty smell."
part replaced was 210-830-07-72, with a description of "temperature" and a cost of 44.50 for parts and 218 for labor. freon was not the problem with mine, just that part. same as yours, i would drive for a few miles and it would revert to warm. stop, park, and after restart, A/C would function okay for a few mins....emits warm/ambient temperature again.
aftermarket warranty took care of the cost for that that and other misc items, minus a $50 deductable.

Check this first
Before you go to alot of expense, check the tension on your accessory belt. If it slips then the computer senses a different RPM between the engine and compressor...it assumes the compressor is about to seize and it turns it OFF. It is easy to check and tighten. Try that FIRST.

The one I have is through an outfit called AFI Management Company, Inc,
dba American Mercuty Warranty Services. Plat coverage. I didn't research this, rather, accepted that which was offered through my city credit union... who has good track record of looking into such member services first.
I used them twice and both times were problem free, totaling over $1k (a/c,
lights not synched to function, weeping cable something to tranny, something in the dash (forget what). The dealer wrench said that initially, the reviewer was a little snotty and after he 'put him in his place' it was quite smooth in confirming coverage and concluded.

Hummmm
I have experienced this problem, only in reverse. As recently as last Saturday, it was cold enough to bump the temp up to about 77 degrees on the control. The air was warm for about the first 15 minutes into the trip, then turn to ambiant air - around 60 degrees which was around the outside temp at the time. I have not experience this with the A/C turning to warm air, but the problems seem related.
My guess is that at some point there is an incorrect reading given to the Temp Command Console and it opens the vent door to take on some outside air. I have tried the recirculation button and it seemed to function, obviously, that is more of a band-aid than a cure.
Somewhere I read that this problem might be related to the emmissions and maybe even the Mass Air Sensor, but I cannot located that thread now.
Thanks in advance for your thoughts, opinions, and experiences.
