this just happened to me too, but it was right after i got rear ended. i left the wreck and they rolled down perfectly, but when i got to the body shop about 20 minutes later the passenger wouldnt go up. I just replaced the passenger window motor about 6 months ago so i hope that the damn thing didnt go out again. now neither of them will go up or down so i am kind of stucm on what to do. is there anything electrical besides the battery or fuse that could be messed up, or am i gonna have to shell out another $90 a motor again?
