SOURCE: 1991 735il. Getting hot air
That is correct...How to correct it will take some disassembly if you can follow instructions and sorta good with tools and have some nerve then get a Bently Service Manual on your BMW... It will be the best 100.00 you spend on the car, If you are frugal then look for a used copy on E-Bay.....
SOURCE: heater not working, cruise control not working
set temp to max 32degrees will turn on the a\c
2. check the fuse for cruise
SOURCE: heater not hot
does the heater core get hot, check the coolant hoses going to the core to see if both are hot, if they are U have a air temperature control blend door problem, most likely the actuator for the door has failed.

PROB NEEDS 2 JUST BE RECHARGED. BUT STAY AWAY FROM THE DEALER. IT IS ALWAYS 3 TIMES MORE THAN A PRIVATE SHOP
SOURCE: When out door temp is
Your PCV (positive crankcase ventilation) valve is stuck and the excess pressure in the crankcase forces the oil up the dipstick tube
Change your PCV valve
In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
