I’m willing to part with it.
I haven’t tested it but it’s a brand new one I believe.
I ordered one when I was putting my truck back together. Found the original when it was enroute. I’m impatient so I mounted the original.

Thanks Eskimomann
I actually found a relay and got the power locks working again
But apparently they don’t make that particular relay anymore and the substitute I found is getting rare too
Hold on to yours - it’s going to go up in value!

I replaced the relay and the power locks now work. But the relay is hard to find.

Since I’m cheap, I used a power door lock relay from a 90 GM car or truck. It’s not a direct plug in, but other than a black wire (ground) the other wires are the same. I had to cut the old plug of the truck, and splice the new relay plug to the truck. Since the original relay grounded thru the mounting bracket, I need to ground the new relay.


The relay I used looks like this. It’s common on GM cars and trucks

This thread saved me, I thank you all. I found a cut driver wire for the actuator motor, my power accessory circuit breaker was blown, and that relay is way hidden and the actuators weren’t even plugged in. Plugged them in, got power. And bobs my uncle. Thank you all
