Issues with my 03 maxima :

1.passenger window switch illuminates and goes down only when pressed down, dosent go up from passenger or driver switch, driver switch dosent roll down the passenger either but every other window works fine with each window switch and driver switch.
2. Door lock switch dosent work period
3. O2 sensor engine light code
4. Front right of car pops when going over bumps in road
5. Interior lights stopped working when messing with passenger window switch wiring, (can't find interior dome fuse/relay)
6. When accelerating quickly after changing gears car gets louder i under the front right of cAr like u can hear the full exhaust sound from motor , (hard to explain the sound)
7. CAr always smells like fumes when running and smokes from tailpipe
8. When starting cAr have to tap gas pedal to stay idle once idling car stays running great and quiet

 

The switch issue is you blew out the bcm jumping it
Replace your window switch remember to buy or get the same color switch look at the bottom of it there is 4 different master switches for the 02/03 years
Your other electric issues are due to the bcm
The loud sound from the engine is most likely your flex section is rotted out in the y pipe also would explain strong exhaust smell

 

The right side sound is your endlinks or the motor mount on that side change both

 

Awesome! ThNks for the help! I replaced the room lamp fuse and my shift lock and interior lights work now. Still concerned about my BCM tho easy to get to but how expensive is it, and how can I find out which master switch I need I think the one in the car was replaced it may be the wrong one too. Just want to make sure I'm getting the correct one the first time so I won't have issues. My gas gauge is not accurate sometimes says 200 til empty then I'll start it up later and will say 170 til empty then next time I start it back to 2 somethin til empty. I ran out of gas when it said half a tank before. Is that cluster issues or some kind of fuel issue?

 

UPDATE: used jumper wire from red/white and black wire in the middle pins of the passenger side connector to the regulator/motor connector pins to make the window go up and down. That works...so could it still be the BCM/SECU or the master switch?...
