Search Auto Parts Search cool evaporator warm dash air Sign up here!   Email This Post Auto Repair Home>> Automotive Repair>> AC Auto Repair Help Forum heavymetal New User Jul 31, 2011, 8:42 AM Post #1 of 4 (2046 views) cool evaporator warm dash air Sign In 1992 Allegro Bay motorhome. R12 system 107 degree ambient 18% humidity 28-30 psi low side 230-250 psi high side 40 degrees at evaporator outlet tube 79 degree air at vents I checked the vacuum control doors and everything works fine. Even unhooked them to operate manually and no change Seems like it should blow colder than it is. Hopefully the problem isn't inside the ac box because it is not easily serviceable. Any suggestions appreciated.

Pressures are right IMO so a diverter door isn't working blending requested temps. Best bet is some vacuum line is messed up, broken or who knows without being there looking? You seem to have a tight system still by the observations so this is some fool mechanical issues or control thereof IMO, T PS: Worked on mega yachts with God knows what creations so have to dig.............

You may have to remove the HVAC housing and disassemble it to find the problem. It may have just lost all it's foam for sealing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

If you're on the road, a quick fix to get you out of a pinch would be to bypass the heater core. Just hook the 2 heater hoses together & this would remove the hot air source until you have time to fix it properly...   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
