My air conditioning is not holding its charge and I can't find the leak. Is there a common problem with this unit? Thnx Steve

 

I had the same problem, the evaporator core in the dash was shot....I have since been told it is a vrey common problem in the Ram. The shop that fixed mine said that this accounts for over 70% of the A/C problems they encounter with the Ram. The whole dash has to yanked out to replace the part.

 

I second that.
