SCREECHING windows...
Getting fixed by MB to the tune of $1750 for both fronts. Turns out the regulators are bad. $350 each one and 3.5 hrs labor ($130/hr) plus tax. Thankfully my after market warranty is covering them (minus my $100 deductible).

YIKES!
When I read "screeching" I though you meant the squeal I hear from the glass against the rubber seal. My fronts do that -- especially the passenger side. I doubt the previous owner ever opened them up.

It could be the regulator or the cable. My driver side was doing that exact noise before the cable snapped and I ended up with a window that wouldn't go up. MB replaced the regulator/cable assembly.
Check the speed your windows go up, if it's slowing down its definitely the regulator.
