Power Window Relay Mod?
 

Anybody have a write up for it? The write up on CK5 isn't helpful to me, I dont have a paid account so I cant see the pics. Anyone have parts #'s? What exactly is the mod? Thanks, Bradley

Re: Power Window Relay Mod?
 

I'm gonna do this on my crew if I ever get around to it.

It uses 2 relays per window, one for up one for down. Just regular relays, 30 amps I think. Instead of the voltage going thru all the wiring and loosing some by the time it gets to the motor, going thru the relay sends a full 12 volts to the motor. I guess it turns slow ass windows into an upside down guillotine.

Re: Power Window Relay Mod?
 

Where do you mount them? Etc etc!!?

Re: Power Window Relay Mod?
 

Keeping my eye on this

Re: Power Window Relay Mod?
 

The two relays per door fit behind the door panel. I can't remember where, I'll have to look at the thread on CK5...

I've done the headlight mod before, so wiring up relays isn't too hard. At almost $5 a pop, could get expensive with 4 doors!!! Wouldn't need much wiring, so find a place to mount the relays, run some wires, do some splicing and done....

Re: Power Window Relay Mod?
 

I'll have my electrical take a look at the diagrams. I'll also see if I can do it for the tailgate window! What kind of electrical fitting d you use on the relay? The slip-on type? (Dont know the technical name)

Re: Power Window Relay Mod?
 

This is right from CK5

I have been thinking about my slow power windows. It seems it isn't just mine, but everyone's. SO I have been seeing alot of topics about adding relays to headlights to make them brighter by adding full battery voltage. And I already added a relay to my starter for the same reason.

So, I am thinking about adding some relay's to my power windows, I looked at a diagram today at work and it didn't show any. I have no problem wiring it up, but has anybody tried this yet? If not, I think I will give it a whirl and maybe do a write up on it.

Let me know what ya'll think.

EDIT, I just got one side done, The drivers, and it is almost twice as fast as the passenger side now. It used to be slower. I used 2 standard bosch relays.
Terminal 85- power from the window switch.
Terminal 30- To window motor
Terminal 87A & 86- to Ground
Terminal 87- Goes to power, I used the junction block on the firewall, so I get as much voltage as possible.

I am going to do the other side, it is just too hot right now. It was pretty simple, and they work soo much faster. It's amazing how much voltage drop there is on 25 year old wires and connectors.
here's a pic of where I put the relays. I took the pic before I ran the power wire to them.

Re: Power Window Relay Mod?
 

That's some good info! I might have to try this on my truck.

Re: Power Window Relay Mod?
 

b454rat can you put up a link to the thread? This would make a great FAQ here, but I want to ensure that the OP gets proper credit.

Re: Power Window Relay Mod?
 

I like it. Gotta try this on the K5.

Re: Power Window Relay Mod?
 

Awsome mod - I'm about ready to add PW/PL to the CUCV and this would be perfect to use since I'm starting from scratch.

Wonder if it might help the wipers and blower as well?

Re: Power Window Relay Mod?
 

Do you really need help down??? My Down is good

Re: Power Window Relay Mod?
 

Not sure about the wipers.....but in my experience with our age vehicles, the blower is getting almost full battery power. Like a drop of less the .5 volts.



Also like to add that if you can find 'em, get the relays that have the bracket part made out of metal. The plastic bracketed ones like in the picture above always break off after not too long, and in this case will create a rattle within the door.

Re: Power Window Relay Mod?
 

I have a few relays laying around and some spare time, I wonder how much of a difference this mod makes?

Re: Power Window Relay Mod?
 

Same thing I was wondering. Might be best to quick try it on your slowest window. I wouldn't even bother running the wire thru the door, just quick wire it up, and see if it really makes a difference before you go thru all the trouble of making it nice.

There are a couple of diagrams in there, not sure if needed or not. If so lemme know what ones and I can get them....

Re: Power Window Relay Mod?
 

I just rewired my 83 using 5 relays. Some guy on e bay sells 5 (5 wire) relays WITH pigtails and FREE SHIPPING for $18.

Re: Power Window Relay Mod?
 

I have thought about this and now that I've seen feedback, I'll be doing it to mine and my neighbor's trucks. Thanks!:thumbs:

doing this soon. I hate waiting on my windows to roll up lol

Re: Power Window Relay Mod?
 

Thanks b454rat! Big help! Now to buy some wire, relays, and learn how to remove/install the door panels.

AMEN!

Re: Power Window Relay Mod?
 

I am definately going to do this mod also..... I just have one question.... Do you need to wire up something additional for the driver to put down the passenger window... Or is that covered in the directions and I just missed it..... I would assume you have to run a wire from the switch on the drivers side to the relays on the passengers side to activate the passenger window from the drivers side???

If I am wrong I apologize..... but I am just wondering what has to be connected in that scenario...

Thanks
Mike

Re: Power Window Relay Mod?
 

This is a great mod. It was a simple mod and well worth doing. I did mine when I had the truck apart. I put my relays just above where the wires go out threw the fire wall to the doors. I felt they would be better protected from the weather. I also cut my wires to the motor about 2" from the motor and added a much larger wire all the way down to the motor .I pulled the original wire back up threw the door jamb to the inside of the fire wall to run the relays. 2 wires up to the relays from the motor, and 2 large wires down from the relays to the motor. It works great. The first thing my friends show off about my truck is the windows in action.

Re: Power Window Relay Mod?
 

Nice, I was thinking of replacing my motors because of how slow they are, but I guess I'll just do this mod and see how it works.

LOL i literally laughed out loud and spit a piece of meat outta my mouth when i read "I guess it turns slow ass windows into an upside down guillotine" haha

Re: Power Window Relay Mod?
 

Just did this on the front drivers side window. Up or down now takes 3 seconds flat, vs 4 going down before, and 4.5 going up.

Re: Power Window Relay Mod?
 

Nice.....gonna have to try this one during my power group swap.

Re: Power Window Relay Mod?
 

Any more success stories w/ this relay mod?

Re: Power Window Relay Mod?
 

my next electrical mod after i finish under hood.

Re: Power Window Relay Mod?
 

been working on this all day now and all i get is a clicking sound from the relays. I've retraced my wiring and its all correct. I don't get what I'm doing wrong and its driving me nutts.

Re: Power Window Relay Mod?
 

Hey there I am working on this also and for me it works perfect
Can you give me some more insight on how you have it wired and I can hopefully help. My drivers side is done and I will finish up my pass side tomorrow.

Thanks
Mike

Re: Power Window Relay Mod?
 

Broke out the test light and found my problem. It ended up being a $1.32 splitter that was interrupting my power source. I just took for granted that it wasn't impeding the flow from the junction block. Windows are definitely quicker now.

Re: Power Window Relay Mod?
 

Hi there.

I am also in the process of doing this mod to my windows and it's definately awesome... Drivers side works perfect, but I have a small issue with the passenger side that I beleive is not even relay related...

Before I did this mod my passenger window would only go down a few inches and then stop..... then I had to wait a minute or so before i could get it to continue down another few inches...

With the relay mod I thought it would fix that issue.... but it did not and now it goes down the same 5 or 6 inches but of course faster before it stops....

At this point I am thinking it's a switch or motor issue.... what else could it be and how can i test to see which one it really is before I go and buy both and replace...

Any help is certainly appreciated...
Thanks
Mike

Re: Power Window Relay Mod?
 

bypass the switch and just touch the wire to power. if it still does it, possibly motor or other related

Re: Power Window Relay Mod?
 

Has anyone tried bypassing everything and going directly from the battery to the motor just for troubleshooting?

Id try but I'm away from home for another two weeks...

Re: Power Window Relay Mod?
 

I'm still contemplating getting rid of the PW. I already have some manual regulators. I really need to make up my mind

Re: Power Window Relay Mod?
 

I forgot about this one. Just might do this on mine when I swap the new motors in...

Re: Power Window Relay Mod?
 

I took it a step further with my harness by converting the switch to act as a ground trigger:...this way, the switch carries virtually no amperage-just a ground trigger for the relays. And, the express down feature is that much easier to install.

Re: Power Window Relay Mod?
 

How do you get express down?

Re: Power Window Relay Mod?
 

Depending on what vehicles you pull them from, the wiring layout might vary but, there are basically 4 wires. One is constant 12V, another is spliced in parallel with the wire to run the window up and then the wire to run the window down gets cut and each of the other two module wires go to each lead. The logic behind the relay/module is such that when a sudden spike is seen when you press the window switch down, there is a capacitor of sorts that "holds" voltage to maintain power to the window motor. After usually 6-8 seconds, the solid state relaxes back to a normal state.

Re: Power Window Relay Mod?
 

In! I'm gonna do this to! And turn 'em into automatics, maybe invest in a higher quality switch than those chrome factory ones that always seem to have problems.

If this relay mod has anywhere near the same effect that it has on the headlights, it will be well worth doing. Headlights are 10x better than those factory junkers. Here's what you want for full auto. No sense in just doing auto down, only to have to hold it to go back up.
