W126, A/C works... only hot air from vents?
What in the heck would cause a car to only blow hot air from the vents? The system is fully charged and the expansion valve is cold.
Maybe those vac flappers? Exp valve plugged? Bad evap core?

hit man,bet if you take a pair of needle nose vise grips and close off the heater hose your car will cool down.problem is the 'mono valve' with a broken diaphram or just full of coolant behind the rubber.normal default is open it needs to work to close.the heater will always beat the heck out of the cooling on a hot day. david poole

 Thanks so much!
