A/C Not working Low - Mid/High!?!?!?

When I turn the knob to adjust my a/c , the only one that works is high. the other three seem to rarely work. simply no air/ac will come out through those 3 (Low, low/mid, mid/high). But occasionally they seem to work and then about 5 minutes into the ride they shut back off and I have to resort back to high and freeze myself to death. Is this a fuse or is it something complicated like the compressor?

 

My guess would be the swtich itself. If the compressor was not working, all settings will not work - even on high.

Make sure you get the Denso-branded part, P/N 87138-04052 (~$25). Older Delphi (GM!) part has poor tolerances on the electrical plug and can cause arcing and burn damage.

 

That was my first guess but I have messed with the switch and knob hundreds of times...

 

New Denso part vs old Delphi part. The Delphi part looks like Eastern European technology... because it is.

 

in the mean time you can stick your hand under the dash on the pass side and wiggle it and it should kick back on. i have to do this probably once a week to keep it going. much easier when in the winter when i have the snow brush in the front and i can wack it with that

 

just wanted to bump this thread....also having the same issues and not sure how to fix it.

 

Hello! Newbie here....but I have a 2006 pre double cab that was having the SAME problem last week...thought it was a electrical problem...turns out, it was nothing more than my cabin filter clogged...hadn't changed it in YEARS......but bought a new one and it fixed the problem...my repair man laughed at me! So maybe that's the problem?
