Hi guys, Having an issue with my heater motor. Seems fine up to about 3 - 3.5 but any higher then it starts squeeling and stops. I have a feeling the bearing has gone on the motor wheel itself. I changed on on my 5 series BMW and had to take the entire dash off to get to it. Is it the same thing with the W208 Merc?. Am I thinking along the right lines or is this a common problem that has a different solution?
