What's wrong with yours? Remember they are case grounded so they need to be rigidly attached to the bracket by the column.

_____________

So we cut the old relay out and now I can't get the "new" one rigidly attached for a good ground.  Any suggestions?

What do you mean? It's bolted in, you just remove the bolt and tighten the bolt to install. What did you cut?

Ok thanks , is possible that the relay will fail and only lock the doors , and not unlock them.? I’ve replaced both switch’s with the same result

Why did you replace the switches? Have you tested anything yet? Just follow the diagram with a test light. the most common failure are broken wires in the door jamb

I have a lot of extra parts laying around the garage from other trucks , took a couple minutes to swap out switches and rule out that the switches themselves are bad . Since I know that they are good , I can move on to other things like the wires in the door etc .... which I’ll be doing next .. thanks guys ....

After a small amount of research, the door lock relays are the same for a great number of cars and trucks, got one from a gm car
