i disconnected my battery so i could reset me ecu for my test pipe. now my passenger side window will not roll down. i try pressing driver and passenger window button and the window will not roll down. what did i mess up this time?

 

try checking the fuses

 

and i know this is dumb but make sure the passanger side window lock isnt turned on

 

it wouldnt roll down when i pressed the button on the driver side either

 

then id check the fuses

 

You misunderstood Huntsmcgee: there's a rocker switch across the front of the window switches in the driver's door. If it's turned off, neither the driver nor passenger window switch will work. Check this rocker switch first, before wasting time on fuses, etc.

If it's not the simplest thing, then check the fuses, etc.

 

I've done that before haha

 

Driver's side will but passenger side will not, with rocker turned off.

 

You dont need to reset ECU for a test pipe or exhaust. Anyhow, I agree check fuses for the windows
