The temperature control relay switch was replaced less than a year ago and the air condition worked, but now it is doing the same thing. I turn it on it worked for a couple of minutes then it doesn't work. Worked like this for a week, and now the air conditioner doesn't work at all.
You need to have the system tested. It sounds like it is either low on refrigerant or there is a blockage in the system causing too much pressure and the system being disabled by the high pressure switch.

either the relay for one or both is freakin out or there is a short in the wirering for those two components

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

Love mine too. I had the same prob with the a/c...found a fix online where you take the switch panel out, take it apart, clean the contacts with alcohol and then write on them with a #2 pencil (coat them with the lead) and then reassemble and it worked like a charm for me. Mine started to do it again this year, but it at the end of summer and I didn't get around to doing it again, but will before I need the a/c again. And time again for front brakes and rotors for me! 85k and going strong!
SOURCE: Temp gauge not working and the rad. fan stay on when car is off
The same problem happend to a customer of mine. I replaced all fan relays to fix the problem. (there are three) also as for the gauge it was the instument cluster itself that was faulty. My answer to you is make sure they replaced all the relays.
