1.I own a 1996 mercedes benz for 15 years. With only 11,850 miles, the temperature / climate control mechanism failed due to being defective part. This was brought to a mercedes benz service center, however it was not fixed which I left unsettled and unsatisfied. 3.
I heard a click and then ac stopped blowing air. It had been blowing fine before this audible click. Research I did says it is a faulty blower regulator which seems to be a common occurrence for this model.
Check engine light was on before. Stopping at the gas station we noticed the smoke coming out the hood. Temperature was rising to a 100 c. Since then even in local driving temperature goes over normal. I am very concerned. Did not check with service yet.
My passenger rear window has completely fallen into the door upon touching the window switch. This has happened while driving and it is a recurring problem. Since I have had the car, I have repaired this issue three times. I suspect that mercedez is using weak parts and is not looking into this issue seriously.
