Power window relay upgrade

I've tried to do a search here on this but could not find anything. Has anyone ever seen this or installed this? Does it work? Is it worth the money? Any info would help.

Re: Power window relay upgrade

i dunno. you could make the same circuit with a couple of door lock relays from other gm vehicles. a trip to the bone yard is way cheaper than that.

Relaying Information

I’m not familiar with that brand however using relays for the windows will bypass the thin wires which cause the windows to move slower than the motors are capable of.

The idea is to run larger gage wires than stock into each door to deliver full system voltage.

Typically you would use 2 relays in each door, so instead of the window switch directly applying power to the window motor, it applies it to the UP or DOWN relay, then the relay applies power to the motor.
