This is the detailed mechanic's report to fix our dash AC. Took 13 hours of labor.
Checked compressor and clutch was engaging. Checked all fuses and they were okay. Checked air coming out of vents and found the vents were not distributing air out of dash vents when in ac mode. Instead air was defaulting to the defrosters. Checked recirculator door function and found that it is working. Checked vacuum at recirculator door and it was ok. Checked for vacuum at climate control panel and it was ok. Checked all vacuum lines a far as they were ACCESSIBLE and they were ok. Started taking dash apart in order to check air box for a door being jammed. During dissassembly of dash, removed air vents, passenger table assembly, and air hoses to vents. Whe removing one of the vents, found the vent is broken on the back side which allows air pressure to escape while air is flowing to the dash vents. Found the yellow vacuum line CHAFFED and broken about an inch away from where it goes into air box. Cut out broken/Chaffed section of line and replaced with new vacuum line. Used a piece of hose and taped it to vacuum lines to protect the lines from chaffing. Reassembled truck. Put AC system in Vacuum, no leaks. Charged system to spec. Steam cleaned condensor. 13 hours of labor. Now our Dash AC is working properly. Never worked like this from day one. Thank you Gambrielli Truck Sales. Felt sorry for the other Thor coach owner whose brand new coach was riddled with Electrical, brake, and AC problems.
