I feel so fortunate I only had one HVAC problem in 26 years of TJ ownership and that was on my previous '97 TJ. A wire cable had come off its actuator connection so it was easy to repair. I think I'd have to live with the problem if something happened to my 2004's HVAC system. Or fly Andy to Florida to help me figure it out lol.
Hey Jerry, I don't know why, but I thought you were in SoCal
