Problem with my E24 635CSI Heating system!..
Hey there everyone! My 1987 E24 635CSI's Heating system is acting up weirdly... The foot well heaters work perfectly and have lots of heat, but the middle - top level heaters have almost no heat at all... I looked @ the diagrams of the heating system in the user manual, and I thought there may have been a blockage in the top "air intakes" under the hood because sometime leaves would blow into my face when driving out of the vents, and when i cleaned underneath the hood i found some gunk/leaves on the right and left sides of the heater/ac intake part (sorry if I am not saying the proper names of the parts at the moment).
& when I checked out the Right & Left side of the air intake box for the Heater/AC it there was no blockage that I could see, I wasn't able to take much apart because I don't have access to many tools or much knowledge to this issue.
Any thought's people?
