Shrink wrap= Heat shrink , lol

Incredible I’m going to do this bcuz I’m sick of not having power window in the rain

This has been the most amazing walk through I've found yet. Thanks so much

Where you buy the switchs and part number?

Hi thanks for the help, I am confused are those two relays controlling both driver side and passenger side windows? I wired mine up but for some reason only driver side works but passenger side window does not.

[@MarreroBuilt]

Indeed it's for both windows. Have you tried making the passenger side window go down with the passenger side window switch?. For some reason mine was working perfect at first no issues what so ever and now I'm unable to use the passenger window switch on the driver side but I can use it on the passenger side. Not sure why I'f nothing was changed and it worked at first I'm going to be looking into it once I get it running. Mine goes down if i hit the switch from the passenger side. Very strange not sure why it does that. Have you figured it out? I think it might be the switch itself.

ricardo m thanks for getting back to me. I’m not sure if the switch is faulty because I tried rolling it down on the driver side switch and then also tried the passenger switch but still nothing. Checked the motor and it works 100percent, I’m thinking if I should add another two relays for the passenger side so it can be switched separately. Will let you know how it all turns out. Thanks

@@ryannaidoo7919 do you know if the window motor is any good? Look up how to connect a car battery to it, its safe.

Hi Ricardo. I'm try your method on my 1992 Primera P10, I believe the power amps are the same, mine is water damaged and both windows are not going down. Will let you know about my progress.

[@MarreroBuilt]

Did you test the motor to see if they are good?.

[@fingerpansiri5280]

@@MarreroBuilt my battery was low but the motor moves. The wire colors on my car are different, but for the motor they are the same. I have the thin blue wire with a white stripe, thin blue with black stripe, 2 thick white wires both with a green stripe, thin white wire with a black stripe and a black one which i believe is ground. I don't how I go about it from there.

[@fingerpansiri5280]

Another thing, can I use the 12V 30/40A relay coz that's the only one I could find!

[@MarreroBuilt]

@@fingerpansiri5280 sorry for the late reply I had to search online for days to find this specific one I think I found it on Amazon, I'm honestly not sure if it blows a fuse just do one window at a time to reduce how many Amp runs through that relay.

Hey so I just tried this and it works only going down tho not upward on drivers side any guess on why? Could it be the motor or do I have a bad connection somewhere

[@MarreroBuilt]

Test the window motor by using a car battery. put the negative on negative and positive on positive and see what happens then reverse the polarity negative on positive and positive on negative terminal on the battery that's how those window motors work for going up and down. Double check your connections it took me forever to figure it out because I am no wiring expert. It work fine for me until I sold the 240 the driver side wouldn't go down from the driver side only passenger can bring it down from that switch for some reason. I think there is a passenger side rellay also I'm not sure. At least you won't look dumb if you get pulled over because your driver side window doesn't go down that's why i mostly did it besides it not working at all at first.
