Question about 1992 Mercedes-Benz E-Class
The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.
