2/ The motors can be overhauled on the early models, these can be recognised by the casing being held together by Torx Screw, these can be stripped cleaned, regreased and reassembled. The later models came as sealed units and can only be binned when finished.

Hope this Helps.

My passenger side window is very slow. I just had the window motor replaced (because the window stopped working halfway up/down). But, the window still seems to "labor" when moving.

Any suggestions appreciated..

Thanks
