No Ac

[Mudddawg]

HI ALL,

 

MY AIR CONDITIONER QUIT WORKING IN MY 09 SILVERADO. FOR THE LAST 5000 MILES I HAVE HAD A RATTLE IN THE DASH. FOR THE LAST FEW DAYS I HAVE HAD TO ADJUST TEMP SETTING FROM COLD TO HOT AND BACK TO COLD BEFORE IT WOULD START COOLING REGARDLESS OF RUN TIME. TODAY AT LUNCH NOTHING WOULD MAKE IT GET COLD. I WONDER IF THE RATTLE AND THE COOLING PROBLEM ARE RELATED. GOING TO THE DEALER TODAY. I JUST THOUGHT SOME OF YOU MIGHT HAVE SOME INPUT.

Never a problem with my AC. It holds the temp quite well and after the latest computer software update, it does a better job at switching between direct air and recirc air.

No clue, but please do report back what they find.

If the compressor seal did not fail, then it most likely is the temperature control module (if this is an automatic A/C system). If you lose refrigerant in the system, the low pressure switch will not allow the compressor to operate to protect the system. A rock thrown by a vehicle in front of you can puncture the A/C condenser could wipe out the system. This happened to my brother in his Nissan Maxima.

 

There is no telling what is wrong until you connect the gauges to the A/C ports and go from there.

 

I have not had any problems with my truck's A/C to date and it is 4 years old. But I have manual A/C, which I prefer anyway.

Turn off the caps and take truck to the dealer. Warranty. Use it.

UPDATE,

 

TURNS OUT MY TROUBLE WAS THE ACUATOR. MY TRUCK IS MANUAL CLIMATE CONTROL BY THE WAY. IF ANYONE ELSE HAS THIS PROBLEM TRY TO GET IT TO SWITCH TO COLD AIR, THEN UNPLUG THE ACUATOR AS IT IS ELECTRONIC.
