Need help solving a problem with the heater on my 535.
When the engine first gets warm you can get lots of heat for about five minutes. Then after that it has a mind of its own sometimes giving a little heat, but mostly no heat at all. My car has the rotary dial with the temperatures (numbers) around the dial.
I also have experienced the same problem with the Air Cond cool for a while then nothing. This mostly happens when it is very hot ouside ~90F. When it cooler outside the Air Cond. will freeze you out.
Thanks in advance
