Might need a new blower motor. Here’s the fuse panel placement….
Thank you! I wasn;t sure if it was a new sound or something I just started noticing after 4 years owning car LOLThe thumping after the car is started is the brake system doing a self check.
Blower motor works. A/C works great. I think its the heater module.Might need a new blower motor. Here’s the fuse panel placement….
I’m pretty sure that’s what it is. Thank you. I web search the part number and noticed a lot of “repair” service in Europe. Seems common I guess. I wish I knew what breaks inside so I can attempt to fixI had a bad heater booster on my 2014. It was repaired/replaced under warranty. I don't have info on the procedure or know if that's your problem, but I can certainly give you a copy of the work order showing the parts replaced.
My heater module malfunctioned a couple of years ago. There were only two settings: ice cold or blazing hot. My mechanic in Brooklyn, whose business is expert at smart, told me only Mercedes could install and map a new module to the car...to the tune of $800. I had the work done and it works perfectly. I hope yours is only the module and nothing more expensive.Blower motor works. A/C works great. I think its the heater module.
