CUTLASS Power Window wiring diagram adding relays to speed up the window motors

[slowcord]

While trying to assist in the recent power window wiring thread, I started thinking about how to add relays to the power window system to speed up the motors. So I modified the CSM wiring diagram to include relays.

All you electricians out there, see if it makes sense. I did a quick rendition with MS Paint. Pretty sure this will work, but I ain't no 'lectrician.

Does the attachment work for anybody else?

69hurstolds might have pulled it to make a revised version with the 87a grounds that were later mentioned.

Rocket powered power windows

I just finished rewiring the power windows on my dads 81 GMC truck (455 Olds powered of course!). It suffered from the typical slooow moving windows. GM G body cars use the same wiring, and suffer from the same issue. All that is required to fix it are 4 single pole, double throw relays...

WTF? I uploaded the newer version on 3/19. Just did it again.

I'll put it here too.

I got a feeling the relays are cheaper and easier to install than that thing. Glad it works for you, but I wouldn't go that route.

I'm curious though. Guy in the video says the unit gets HOT. I'm trying to figure out, unless you're up and down many times without stopping with the window, how is it going to get that hot. It should only operate for about 4 seconds or so at a time. Plus, that video with the first two minutes wasted on rotors and all the included funky transition stuff was just simply annoying. Hard to watch. JMO.

Something that I haven’t seen mentioned in this thread yet, is how is the actual power with this conversion. When I say power, I mean torque. Yes, we’ve established that they’re faster, but are they any more powerful with any of these conversions?

Reason I ask, is because with the new weatherstrip seals I’ve installed, there’s considerably more friction and drag than before with the worn out 40 year old originals. The windows (both) go up 95-98% of the way and then just run out of jam to go the rest of the way up. I end up having to crack the doors open to get them to go the rest of the way up. More speed would be nice, but a more powerful modification would be more helpful/useful to me.

Be thankful you have the early a/g-body type motors. I didn't put them on a meter, but in my opinion they're actually faster and stronger than the newer, weaker versions. Of course, leaving the windows tight over time may loosen up those seals enough to soon close all the way. Perhaps condition them up with some weatherstrip dressing to not only keep them supple, but helps the glass slide over them easier as well.

I use Z-10 from Zaino, but you can use 303 rubber protectant as well. Either one is a bit pricey, but well worth it, IMO. Some of the old geezers have told me they swore by a thin film of dielectric grease on the weather seals, but it's, well, grease.

I’ve considered coating the seals in something as well, but like you said, it’s gonna leave some sort of residue on the glass. Least attractive option for me at this point. I do however have a sh*t-ton of 303 kicking around from soaking the AstroRoof seal in it, so maybe I’ll try it.

I’d still like to hear some feedback from the guys that have made their power window motors faster, guys are they any more powerful as well? Steve (pontiacgp) I know you’ve added relays to yours as I remember reading about your struggles with them, care to weigh in for us? How about 565BigBlockChevy?
Anybody else??
