2010 GMC a/c low pressure switch Where is it.

[Roger S]

I have a 2010 GMC Sierra SLE 5.3L and I am looking for the low pressure a/c clutch cycling switch.  Where is it????  And NO, it is not on the suction line accumulator.

Check the hoses coming out of the compressor, it may be located there.

 

And it may only have 1 switch on these vehicles, I don't have the right information look up in front of me at the moment but it might just be a high side pressure sensor on these.
