I have a 1999 Durango 5.9 4x4 and the AC has been fine up to a couple weeks ago when it stopped blowing cold air out of the front and only cold out of the rear. Freon levels are good. I checked the pressure and it’s also good. Vacuum is good. I drained and refilled AC and still nothing. One thing I did notice is the evaporator lines are not getting cold. Any ideas of what the problem could be?

 

check the drier/filter or expansion valve for the front (i believe front and rear have separate units for these, but i can be 100% certain).

the fact that the back works and the front doesnt tells you that the charge is good (or at least acceptable) and that the compressor is working fine, its something specific to the front system. Since the lines are not getting cold i would be looking at the expansion valve first then the drier for a clog.

 

Thanks! I’ll definitely check both of those out. I’m hoping it’s something cheap like a valve.
