Does anyone know if there is another way to repair/replace the potentiometer without removal of the dash on my 1993 190e 2.3. My mechanic says this is 8 hours labour. I am not getting any heat and we troubleshooted everything else.heater valve,control unit etc.
Apparently the 190e has a complicated climate system and the potentiometer is not getting any feedback to open the valves for heat?
Any suggestions?
Thanks
