W116 windows not working

No windows go up without me pulling them. On some, you can hear the motors, on others--nothing.

is it safe to assume a window regulator repair kit may likely cure the windows where I can hear the motor, but windows with no sound will need a new motor?

Thanks again

If it's like the 108, the diagonals are controlled by one fuse - LF and RR by one fuse, RF and LR by another fuse. Check the fuses, make sure they're good and CLEAN, if they arent clean BUY NEW ONES, and make sure the fusebox's contacts are shiny as well.

Hard to say if they'll need new motors or if just a repair kit will work. On the 108 there can be different problems, from a bent frame (causing gear misalignment) to a cracked frame or busted gear.

thanks--I realized I should check fuses before I do anything $$$!
