When I rolled the window down all the way it wouldn't roll back up. But when I press the up button nothing happens. When I press the down button I can hear the motor and the door bulges a little bit. Before this happened I would roll down the window almost all the way down and it would stop so I pressed the up and down button it would roll back up.

When I Press Down On The Gas Pedal Lightly It Shifts Into Drive ! Not A Good Idea ! This Procedure could Wack The Gears! Transmission Oil levels Is OK ! What Kind Of Adjustment Is Needed ? Recently I Install A Drive Belt ! The Tension Is Just Right ! !!

I would like to know what I need to do in order to fix this problem as its getting warmer and it keeps draining my battery. I'm not a car guy but if told what to do I can figure it out. Any help would be greatly appreciated.

Also, what parts should I need and is this a job I can do or is it going to cost an arm and a leg. Thanks for your help

Doesn't always stall and when it does it is sudden, with no warning. I notice the automatic parking brake release does not work, which makes me suspect a vacuum leak either with that actuator or elsewhere. Could that cause the sporadic stalling?
