2015 Escalade AC clutch not engaging

[Cadi786]

I have a 2015 Escalade and the compressor clutch is not engaging. Clutch seems to turn freely but does not engage with the AC on.  Is there a AC relay or fuse that could be causing this ? And if so, where is it located ?

 

 

Thanks,

Could just be out of refrigerant due to a condenser leak. Look for oily areas on the condenser, usually on the sides or bottom - that's a leaker. Extremely common problem in this model year range.

 

Fuse is probably in the under hood fuse box. Could be a relay in there as well. If you jump the correct pins (Be advised if you jump the WRONG pins you COULD smoke the computer) on the relay and the clutch engages, then everything circuit-wise is good - wiring, pressure switch, clutch coil. You will then need to figure out why it is not receiving the command for clutch engagement. Anything from low refrigerant to a faulty pressure sensor will do this. If the pressure sensor is saying there's 0 PSI ... or 600 PSI, the clutch will not engage.
