My drivers door check strap has been popping loudly for the past couple of months on my 84 190E. So I add some wd40 to it to shut it up (while in a rush to an appointment) and then the door wouldnt shut! The thing was stuck in the fully open position like a broken wing. Or like a broken collar bone.
So I forced it shut, bending metal all the way. Great? No more popping and no holding of the door while open, but I what I didnt bargain for was now the window will only go down half way.
Ugh. I ordered a new strap. I have not taken the door panel off yet, but I hope I didnt ruin the regulator or something else in there.
