It feels like its blowing hotter air like the heater is on. I pushed every button, spun the temp wheel and no difference.
Seems like a blend door motor is stuck.
The A/C has been working flawless for years.

Bmw's (e53 included) don't use a blend door. Instead they have a coolant valve that controls how much hot coolant flows to the heater core dependant on hvac temp selected. On the e53 3.0i it is located on the driverside of engine bay sidewall below strut tower.
