having trouble with the power windows on my 99 maxima. sometimes when locking or unlocking with the key fob, the windows go down. I cant get them to go back up normal way. I have to take of the door panel and jumper out the master switch. I also have to do the same to the passenger side. I went to junk yard and ordered a new master switch, installed it and still nothing.
any help would be greatly appreciated

 

This is different. While the key fob can make the windows go down, it should only happen when you unlock the doors and keep holding the unlock button down. Should not happen when locking the doors.

I don't think the key fob itself is doing it. It could be the key fob receiver module in the trunk or the BCM (body control module). Try disconnecting the battery for 5-10 minutes to reset the modules and see what happens.

 

Stock key fob and alarm? Remote start?

 

^^^^^ Good points. I should have thought of those.
