2015 Silverado AC Clutch Relay

[Dan Foley]

I have a 2015 Silverado High Country. It only has 44740 miles. All of a sudden the AC went out and the Clutch does not engage. I have check fuses but am unable to locate the AC Clutch Relay. There is not a relay in the under hood fuse box in space 71. Haynes states the location is there. I have checked a 2017 Silverado LTZ and it also does not have the relay. Any suggestions are welcome. Thank you

AC failure is common in this series truck. It's either the condenser, or one of the lines connected to the compressor.

 

My guess is that you have a leak, and the pressure switch isn't allowing the AC compressor to kick on. It's designed this way so that the compressor doesn't run dry and grenade on ya.

 

I'm dealing with a leak right now... Google search it and you will see what I mean.

 

Good luck!

Just about guaranteed condenser is cracked and Freon has leaked out. Happened to me last July.

Is it Micro Relay 67, "A/C CNTRL"?
