Hey guys I have a 99 C43 and it's weird, my two front windows don't work nor do the side view mirrors, at first I was like crap my motors are bad which is pricy, then I spoke to MB and they said it might be the modules, which also might be pricy, but when the weather gets warmer, like mid to upper 50's, it starts working agian (like today) I live in the NY area temps been around the 30's and 40's, today it hit 60 and they started working, what could be the explanation of that? I'm selling the car and this is obviously a problem that will hinder my chances of selling. Also when I turn the car on theres this buzzing sound on the over head, it buzzes for about 20-30 mins while driving then turns off, what the hell could that be? hope to find some answers later
