300E WITH THE SAME TYPE PROBLEM: HELP
If have a 1991 300E with nearly the same problem with my climate control system. The unit was replaced about a year ago - but I had not noticed that the temperature control was not accurately reflecting the cabin temperature.
The main problem is not enough heat (unless you put the wheel all the way to max.) If I put the wheel on 75 degrees - it remain only about 65 in the cabin. So, the temprature management part is out of whack! Also the blower fan always seems to be on at a medium level (no matter how long the system is on). HELP!
I performed air intake test on the sensor in the sunroof control (using as small piece of paper to show the suction).
Well, I think the problem is either the wheel, out of adjustment, Or the sensor (in the sunroof control) is not providing the proper ohms.
ANY thought on what might be causing my temperature problem?
If it's in the sunroof control - how do I pull it down to get at the climate sensor?
THANKS SO MUCH!!
