Just had my AC in my 06 Dodge diesel replaced in march went out again in July repair man had to replace it the second time for free though.

Friends have had the same truck and had a lot of AC problems seems like a recurring problem in the 06 dodges. Also had a door break off in the AC vent in 08 kept air from flowing through the Vents like it should. AC problems and an 06 dodge seem to go together sure is a shame truck is still running great other wise no other problems except a few electrical problems.
