Thank you I will double check and add refrigerant.

I just did the flaps test and it looks like right and left diverter flaps didn't operate. Could someone provide schematics (how to reach them and check / replace (part numbers would help)).

Could this be related to the recent blow motor change that was done by my mechanic? He replaced blower and regulator, however did not install the plastic pad (he said that it was not neccessary).

I have 97 E420 and blower had to be replaced with the regulator because the one I had would not fit the new blower model.
