Hello, I have the SUV listed above that will not blow cold air. Tried recharging the system and it did not work, what would be the next plan of action?

Good morning,

I need the high and low side readings of the system. You can rent a set of gauges at a parts store or buy a cheap set at Harbor Freight.

Does the compressor come on line? I will attach a wiring diagram for you to view. If you have a test light or volt meter, we can do some checks.
