ERRRRR AC PROBLEM again!! after I bought new ac blower motor (w140)


I bought a blower motor with regulator for my s500 1995 4 door sedan (w140). After a while.. the passenger side far right ac vent started blowing warm/hot air when my ac settigns are on max cold. Also I have noticed that the vents to warm the windshield which are located on the top of the dashboard are also blowing hot air.. the middle vents and driver side vent is blowing cold air..but thats not good enough.. they should all be working fine.

Sometimes the AC shuts off by its self and displays an F on the driver side menu and a backwards F on the passenger side menu. WHen I try to turn it back on, the buttons don't respond so I have to open the hood and remove a fuse and put it back in..

Any ideas??

Sounds like a possible controller problem. The heat would be coming from one or both of the pulse width modulated water control valves not being held closed. This is often the valves fault but both units are expensive so one would do best to test. The water valve should be tested both electrically (power and ground keep them closed) and functionally (clamp off the water pipes to verify inside cool temp).

If that is the case, I hate benz now. I fix one problem and another starts. What kind of car is this?

(I dont really hate them) but it is getting frustrating now
