Hi,
The car is a W210 E230. The A/C blows cold on the right side and right center vent and warm air on the left and left center vent.
People say it must be the DuoValve part.?? I want to be perfectly sure first before I purchase this part since it is quite expensive.
To be sure, I pulled out the error codes on the A/C switches and was expecting a B1417 code (duovalve left) but this code did not come up.
What came up are B1416 (coolant circulation pump) and a B1226 (in car temp sensor) Is this related to the aircon problem??
Thanks for any help..
