96 s14 power window sw. Make do/ repair

Postby Randall32 » Sun Jun 06, 2021 5:02 pm

Here is a video I made to possibly help someone else. The driver side power window sw amp is bad, and would not ground the passenger window to go down. This explains how I made it work. After I made the video I did notice that the relay made a strang noise it the window lock was engaged and you tried to operate the passenger window.

Slick workaround! If you popped open that master switch you'd find a goofball two-coil multi-pole relay that has NC throws leading to the passenger window. Your actual problem is probably in there. Because it's a series circuit, when they fail closed instead of open they can even make the passenger side switch operate backwards. It always sort of peeved me that Nissan didn't just use two smaller relays, then the circuit boards could be easily reworked. But that's a great circumvention, thanks for sharing it.

Thanks, I did take the cover off the driver side sw. But it didn't want to disassemble very easily. I didn't want to break the only sw. I had. So I kept looking for alternatives. I will go back and put something under the lockout button to make sure it can't be engaged.

Yah, with a stuck throw in the master, your relay and the one in the master may be fighting one another under some circumstances. That's probably your noise, so disabling the child lock is probably a good idea.
