So recent 1984 Cutlass H/O and the power door locks lock but, don't unlock.

So I've read the post about cleaning copper relay n switches . If that all fails were can I find the relay switch . I didnt see it behind the ecm/ kick panel.

Not sure where else it would be, theres an opening on the passengers side behind the ECU that it sits in and the mounting tab on the relay is also the ground. The problem was, GM thought using the screw that holds the relay to the body would be enough to ground it. Ive found this not to be the case. Others can give input on where else the relay might be but once you do find it, I would make sure its grounded properly. Take wherever it is mounted to down to the bare metal so it gets a good ground.

edit: I was able to find a picture I took of how it’s mounted. Notice how I sanded the paint down on the area that the relay mounts to to make sure it’s grounded properly.

This is what the relay looks like. It's in the kick panel....look harder.

They are also made out of unobtanium. If you can find one, it will cost you. The one below is only listed for $175.00. GM p/n 20306055. Fits 81-88. (For you 78-80 guys, you can find it under p/n 20040281)

Here's a diagram that may help. It's for an 87 but your 84 should be similar.

Doing a little snooping around, it appears there are possible alternatives if you need a new relay without spending 200 bucks trying to get one, but you need to do a slight amount of work. It looks as if 20334449 relay is the same relay as the 81-88 with the exception of the bracket. The ground on these is normally soldered to the far end of the relay cap that is crimped on, and the ground is via the bolt to a steel part of the body under the kick panel. If you can solder, you can remove the metal cover/cap from both and swap them, and re-solder the ground to the cap and recrimp your existing cap onto the new relay base. BOOM! Bolt it in place and rehook up your wire plugs. The other option is if you can mount it with the existing bracket. I've never tried, but it's behind the kick panel anyway so who's going to see it. It just has to be grounded to metal to work. Or run a ground wire from the cap/bracket to ground somewhere if you mount it to non-metal stuff.

Standard Motor Products (SMP) was a supplier to GM for the relays like this, apparently. Even has the GM p/n stamped into the bracket. Here's a suitable SMP RY60/20334449 relay on fleabay, about 50 bucks:

GM pickup trucks with PDL in the 70s/80s era have the same relay with a different bracket. Those are also good candidates for swapping caps/brackets if you run across a good one. GM p/n 14056552.

And if you can find an SMP branded one, the actual 81-88 relay 20306055, it's under SMP RY547.

That's it, no more researching this for me.
