Is it possible that the flap door inside the dash of my 94 C220 could stick during hot weather? If so, what part is actually sticking? The car will not blow a/c out of the center vents when it gets hot outside. I have to run it on ec for about 5 minutes, and sometimes back and forth from ec to a/c before it finally starts blowing from the center vents. When it is not too hot out the system works perfect!
Thanks for any ideas out there! Your input is greatly appreciated.
