Heater Controls 87 300E
I have difficulty getting heat using my climate control mechanism.
The best way for me to get heat is to push the button for the defrosters. The other buttons activate only the fan and not the heater. I can hear clicking sounds when I turn the temperature control knob and when I push any of the control buttons.
After the car has been running for about a half hour all the buttons seem to work in that the heater seems to respond as it is supposed to.
Any idea what I might trouble shoot in order to correct the problem?
PS I did a couple of searches but there are evidently different systems for various car series. Any information on the 1987 300E will be helpful.
