I was looking at my power window setup, because I see these big relays on ebay that say they are for power windows and mount behind the kickpanels. But I do not see anything on my harness or in the electrical diagrams that mention anything about a relay.

The windows connect to the voltage (ignition) regulator and the 30 amp power top breaker on the firewall according to the diagram.

Am I missing something? Is it for real?

You don't see the power window relay in the 1969 assembly manual because it was installed by Fisher Body. The circuit draws power from the horn relay through the fuse block "ACC Fused" cavity and has no circuit breaker - those are only used for the power top feed.

:beers:

John, thanks, but I guess I am still fuzzy on the details. I was not looking at the assembly guide, I was looking at the Fisher manual.

And here is the Fisher wiring diagram for F bodies (pg 16-8) and I do not see a relay there. I see a relay in the power seat diagrams though. Is this another Ebay fast one?

Kevin, I don't know much about 69 cars, but the 67/68 cars do have a relay in the drivers kick panel, and the window harness does connect to it. I can't remember if I have a pic in my reference web files, you might check there. I will look when I get home tonight and see if I have a pic of it.

Scot, I layed out my harness pieces and found all the parts and there was a plug that matches the relay one. So I bid on it. Hope I get it, but that part is a long way away. I still need to see where it attaches behind the kick panel. Thanks!

there are 2 dimples in the kickpanel area for locating the relay. here's a couple of pics. note the harness coming thru the jamb area. there is also a 30 amp breaker located on the firewall near the brake booster needed for power windows. i can post a pic of it too if needed.

Thanks! That helps a lot. Since I have convertibles, the breaker is already there for the power top. But if you could tell me how the power window harness plugs into the breaker, that would be great. Thanks

i'm not sure how both power windows and a power top would be hooked up at the same time. mine is a coupe. perhaps there is a second jumper coming thru the firewall for the windows.

i vaguely remember seeing jumpers can pierce the firewall to the side and also below the fuse block. maybe a second jumper is needed.

i did notice that 68's and 69's had different style plugs on the end of the power window harness that fits the jumper. make sure you get the jumper with the correct end. Rick's should sell the jumpers for either year.

The relay is on the extreme left side of the diagram where it says "Ignition Relay" :)

Oh :clonk: I thought that was the voltage regulator. John, thanks for straightening that up!

OK, Found a power window ebay auction from a firebird. And inside was a pic of a relay that does not look like the relays on ebay. Then I remembered a mystery relay I found in my boxes (not with the power window stuff though). It looks like a horn relay on the top and the way it mounts, but the spade connectors match the PW connections. It has 914 12 v stamped on the underside. Could this be a factory original PW relay? I will post a pic tonight of it.

Here is the mystery 914 relay and a pic from the auction which is stamped 990. Any thoughts?

i doubt the 914 relay is correct for your power windows. i'm sure the correct relay attaches with 2 screws, not 1 screw and a pin like the 914 pictured. you might start another thread asking for identification from the numbers guys. i'm sure they can trace it.

might do a search on ebay for the 914-12v relay, maybe it will be identified.

also might do a search on ebay for a power window relay and see what comes up. a lot of times guys just list a part without listing the cars it fits.

Rick's doesn't seem to reproduce the window relay. but a search for relay pulled up ac, cowl induction, headlight, so there's all kinds of them. i personally wouldn't hook my windows up to the incorrect one, it could damage something.

you could also try your local parts store and see if they have something that will interchange.

I am watching some relays on ebay, we will see. If I get one, I am going to ohm out the relays and see what pin is which. There is not much to relays, as long as the current is flowing in the correct direction, they can be used.

OK, hit the books and did some real research, not just skimming. The relay in the power windows circuit is to de-engergize the windows when the ignition is turned off. So you have to turn the key to accessory to get the windows to work. Makes sense now. Since the power for the windows comes from the same 30a power convertible top feed, it has power with the key off, so GM had to put the relay in to stop the windows from getting power and hurting people while the car is off.

With that said, I took a close look at the wiring diagram, the inside of the relay and the wire colors. The 914 (must be a PW relay from an earlier car) is a perfect match inside for the PW relay fuction. Orange power wire goes to arm that moves, pink from "acc fused" on fusebox goes to the coil, red/white is the lug that the arm (orange) makes contact with to complete the power circuit while coil is energized.

I'm good to go after I restore the 914 relay to full operating condition. If I win the auction, it will be a spare. :)

Cool, 3,000 posts!

I recently ran into the need for a pw relay on a 69 convertible I was working on at the shop. As noted no one seems to make a replacement. I used a universal high blower relay for a gm car. As you noted relays are not rocket sceince as long as you hook them up to do what you need. You mentioned restoring the 914 relay. I recently found a vendor down in Fla. that does actually restore relays electrically not cosmeticly. Do you have the same capabilities? This guy has all the coils and contacts needed to do the job. I have hunted a long time for just such a vendor. I have his name and number at the shop if anyone might need it.

I am not a pro, but I can file contacts, glass bead the cases and make sure it functions correctly. If the coil turns out to be shot, then I will attempt to rewire the coil (but I hope I wont have too!)
