Did you replace the HVAC blend doors?
Is the fan clutch less than 5 years old and a MOPAR unit? (Not iffy aftermarket or parts store trouble.)
Is the compressor turning?
If so are the A/C lines at the firewall both getting cold?
If you don't have voltage to the compressor coil, not turning, not these have a TIPM that fail like a fuse esp when a coil shorts out when burning up. It may be able to be reset by a dealer.
