Last night i was driving and the window went down all by itself just as it would when you went to open the door to allow air flow. Now the window stays down that small amount to let the air flow unless I put the window up with the switch, so when I get out of the car & the window drops it stays down. Any ideas?

 

Sounds like you just need to reprogram your window's operation, as per your 2007 Mustang owners manual? With ignition key switched on to first position (music plays) and the engine off, run window all the way down and then all the way back up. Hold it in the up position for about two seconds with the door rocker switch. This reprogram will usually fix that problem? That is, if nothing is broken from window ice jams? CalStang.

 

Thanks CalStang that seemed to work. Appreciate it very much
