Just replaced the window regulator and motor on my rear passenger door after buying the car with both rear windows unable to go up or down via door controls or master/driver controls.
After replacement the window won't work at all using the switch on the door itself but when holding the drivers control the window goes up and down after a while but only after holding down the button for a long time and even then it seems to pause halfway and then come all the way up.
I can see the window symbol light randomly come ON and OFF on the rear passenger door card which was happening even before I replaced the regulator but I still don't have full control of my rear windows.
(Currently waiting on the regulator for the drivers side rear so I can see if the same problem happens)
I have tried contact cleaner in both the window switches and the main door loom but still no success.
Can I swap door card and switches from side to side to trouble shoot?
Any help is appreciated
**UPDATE**
Just finished the same job on the driver side rear and it works perfectly, both the door switch and the drivers switch make the window go up and down smoothly. So something is definitely wrong on the passenger rear.
