I tried to install a window modulator to have it auto up/down for alarm but now the passenger window isnt working.
The driver side works fine, and it can also control the UP on passenger only.
The pass. side does not function at all.

The windows both goes down when topdown is engaged. I have to use the driver side controls to put both windows up.

So my problem is the pass. windows doesnt go down at all only if I put the topdown.
I dont know if the control switch of pass. is broken or if its a wiring problem. Can anyone shine some light so I know where to look, dont want to buy a new controller switch and its not the culprit.

TIA

 

I know it's super easy and you probably already checked but did you look and see if A. all controlers (window buttons) plugged in and B. Fuses are good (doubtful but worth a check).

 

I had a similar problem where my pass window would only go down but would not go up. Turns out one of the pins in the window switch was bent and wasn't making contact.

So it might not hurt to look at the window switch where the plug plugs in and make sure all the pins are straight.
