My AC system started acting up end of last year. What happens is I get only hot air blowing while in AC mode and it's really hot.
I have tried using recycled and outside air setting but that doesn't make a difference.
Today however it kicked in and blew ice cold. So it would appear that it's not a coolant or compressor problem.
Any one have thoughts or similar experience.
Thanks much for any ideas

Possibly the circuit board is getting a bad connection.
Turn your radio on, press & hold the on button, then press the seek arrow up at the same time, the temp control will display. Turn temp ****, 0 thru 16 should be displayed, 0 being cold, 16 hot.
If it doesn't transition smoothly the board connections likely need to be resoldered.

many thanks Big Cajun I will try this today. I will post my results.

I got to the controller window but the temp ctrl **** doesn't effect the indicater which is stuck on 16 HOT.
Would this still be the circuit board or the temp **** on the dash? Also is that circuit
board easy to get at if I need to replace or resolder it? Maybe all the parts just need a good cleaning.

It's a common problem for the resoldering .
Radio has to come out, there's a DIY somewhere in the DIY section.
I need to do mine, but I can still get it to work by messing with it. I'll wait t'il it no longer works.
Good luck!

Ya I find fiddling seems work sometimes as well. I appreciate the input BigCajun.

Yep. Fiddling with it worked for me for four years. Here is the DIY: No Heat? Repair the Heater Control
