I am wondering if its normal for the windows on the 2 door gp's to roll up slowly? Both windows seem to go up slowly but the passenger window is a lot slower than the driver side and sometimes it stops before going all of the way up, when it stops I have to let it down a little and try rolling it up again. The windows have be rolled up one at a time otherwise if they are done at the same time they barely move. Any ideas what could cause this?
