97 sable wagon front passanger window

My 97 sable wagon seems to have an intermittent problem with the power window on the front passanger door. Sometimes works and then not!

Just wondering if anyone else has come across this prob, Not sure if it is a bad ground wire or if the window is jamming in the full up position. The interior lights dimm slightly when trying to roll the window down (when it is not working).

Does anyone know of a fix for this or is this a dealer only fix thing?

Thanks

I just started having the same trouble with the two rear windows on my 97 Sable wagon--both quit working at the same time. Then they started again. There is a similar post on the Taurus forum. No solutions yet.
