I picked up my car (2003 TL-S, 106k) from a transmission shop (I recently got the tranny rebuilt and they wanted me to bring it in after 2 weeks for a routine checkup). I drove it around town at least 50 miles so the battery should have recharged if it was low. I parked it at home and listened to the radio for 10 mins while the engine was turned off. Then I tried starting it but the battery had already died and I had to jump start it.

Since then, the battery hasn't died again but when cranking the engine I noticed it takes a little longer to turn over, like the battery is weak, and the weird thing is that the back passenger window rolls down slightly (maybe 1 cm).

What the hecks going on and do you think the transmission shop might have caused this problem by just doing a checkup on the transmission?

 

you should head to an auto parts store and get your battery and alternator checked out for free.

if the batt is not good, replace it.

 

So the battery or alternator can cause the window to roll down?

 

Looks like it was the battery causing my window to roll down. Took it back to walmart and they replaced it free. Weird how a bad battery could cause a window to roll down when starting.
