'95 Sc400 Heater Control

Recommended Posts

Last year I had my Climate Control Module refurbished because the display was out and the A/C was not working. Recently the heater started acting up, and I'm wondering whether the CCM controls all HVAC functions such as fan speed, etc, in addition to temperature. The display is fine but no matter the fan setting, it's on High. Temp control is OK, but even with mode set to blow at the feet, air comes out the dash vents too. I've checked fuses, etc, and find no problem so I suspect CCM again....can anyone verify these symptoms fit within the CCM's range of influence?

I have the same problem.

My fan always blows on high but the temp controls work ok everytime.

But my display is out too so I'm gonna buy the whole new climate control unt.

I know it's expensive but that's th only solution when these digital things starts to go bad.
