W140 Right side heat
1996 S320 has right side het that doesn't blow hot air unless thermostat is set at max. Is this a thermostat problem in the dash?
Also have air leak around windshield. It's not the original glass. When the weather turned cold I think the sealant shrunk. I was thinking about using silicone sealant once I got the molding off. Any one know how to remove either left or right side molding an the chrome strip at top of windshield.

If the heat both sides aren't equal when the same temp is selected then the heater valve(DUO) may be at fault. IF you un-plug the connector at the valve then both sides should get very hot.
