I also have been having a problem with my power window. Driver side. I already had to replace the pully system once. then the damn thing broke again of course when it rains. The part where the motor connects to the main pulley I don't know the technical words, but I think i can go to a junk yard and just gut another one. cause the cable is still in good working condition. Also my keyless stoped working. Put new battery in and only the panic alarm works!! Any advise? Please help
