03,(corrected but the same) Tahoe with auto air and basic rear air.
AC ran on defrost all winter. Went out this week and NO cold at all. Have determined the following:
Clutch is not working.
Jumping pressure switch plug did not help. one side of was hot with 4.8v.
Static pressure was in the normal Green range just fine. NO evidence of past leaks.
I from O'reilly's that there are two ambient temp sensors if the front of the truck and one may be related to the AC working or not.
Today I also noticed that the compass an temp in the mirror went crazy today, sometimes I worked sometimes it was off, sometimes it flashed some symbols and maybe 188 something then off or correct, kept going back and forth.
Have not been able to access the clutch yet, Can I hot wire it for a test?
Is it one of these sensors the clutch or what. Is an OBDII code reader of any assistance with AC issues?
I am new here but have been on Dodge Cummins diesel forum for years and have done extensive writing there on my 99 Dodge with 766kMI on it. But do not know much about air beyond basics. 69 year old retired and full time fisherman.
Any thoughts . thanks in advance.
