2010 grand cherokee does not blow cold air when a/c is on.

Add dye to a.c. Check for leaks. Be careful it displaces oxygen. ( check floor around center councel ) Check compressor runs when charged. It wont run when not charged. Actuate blend doors with engine off key in run posotion listen for movement or binding Check wiring And switches Good luck and have fun

check the compressor clutch if it is turning when the aircon is on, if not check the fuses, if the fuses are ok, possibly your compressor coil need to change.

Wrong Compressor wont work if charge is low. H block under evaporator very common to leak. No fuse is circuit either. Compressor runs off internal relay of tipm module on 10 grand jeeps

semi related with a different twist my 2010 gj w / dual control started with passenger side note blowing cold. Did some research on blend doors and tried moving the driver side control to full hot and back to full cold it stayed hot am Ilooking at blend doors and how do I get to them
