Climate control not working
 

It was working then stopped, started working again. Today it doesnt work again, and it is vry hot outside! What is going on? Does anyone have any idea on what could be wrong?

Most likely it is the Final Stage Resistor. There is a DIY on the home page. You can get the part for 70 bucks from AutohausAZ.com. In the DIY procedure, you don't have to remove the glovebox. You just need to contort yourself under the footwell.
Hope this helps, and I hope it is just the FSR.

Also check that the aux cooluing fan in front of the radiator is working with the Ac on.
If all these are OK then go to a local AC shop and have the pressure checked. I just had the 2 service port valves replaced due to leakage. $22 for the parts fraom the dealer and my local "guy" did the draw down and re-charge of the AC system when the new valves were fitted.

Zulu95 well even the heater is not working so i was thinking it might not be ac specific
I thought a failure with the final resistor usually generates erratic air flow. Sometime it would not blow and sometimes it would blow at max without being able to control it via the AC control panel. Mine was working normal, then not working at all. i can feel the cold air, just no fan. as far as ac light i can see light turn on and hear compressor kick on just no fan speed hot aor or cold.

My sypmtoms matched your pretty well. You definitely have the FSR problem.

For 3 days the front blower didn't work at all.
For 2 days it worked fine, with total control.
I parked it for 7 days, then found I had no control at all with erratic fan speeds.
Throughout the ordeal the rear blower worked fine, with nice cold air.
I replaced the FSR and all is well.

Does the display die at the same time?
 

i had a problem with my HVAC system dying sporadically. the whole thing would be dead, no response from the buttons, no display.
i pulled out the control panel unit (really easy, just pops out) and cleaned the contacts. put it back and haven't had the problem since.

Does your blower works erratically? does it stop and start randomly? If yes them it quite probably the final stage Resistor.

The blower problem could be the FSR but others have had that problem and it was the head unit. There are at least 2 places who have ads in the Roundel Mag that offer repairs to the head unit for much less than a replacement from the $tealer. They also offer repairs to the gauge units which means you do not need to have it reprogrammed as you would with a new unit.

:iagree:

My display works perfectly, all buttons work fine, just nothing happens, no fan. At speed I can feel cold air coming into the car from the AC being on. The rear AC fan works fine
