Time delay relay
Hey
My name is Greg, new to forums. Just bought a 1988 dakota LE. Has the v6 3.9 and recently loaned it out came back with what appears to be a broken time delay relay or ignition lamp time delay relay. This relay is on the fuse panel and is round, 3 prong thing looks like a capacitor. This part is now discontinued. Does anyone know where I can get one? What does it do? Would it affect my stereo becuase it no longer works?

It won't affect the stereo; it's there to delay the interior lamps turning off when the door closes (specifically the ignition key light, but there's a few other things on it); and whereas it's listed as NLA, it's still available from other places besides the dealership.
The part number is 2889565, and as I type this, Ebay has several at https://www.ebay.com/sch/i.html?_fro...+Mopar&_sop=15 . Also, if you have a pick'n'pull, you might be able to pick several up.
Finally, if nothing else, a time delay relay can be built to plug in its place. I've not had to do that yet, thankfully! But the time delay part is pretty common; the main problem is one that fits.
I attached the two pages concerning the time delay relay as a PDF to this message. This is from a PDF of the Chrysler Factory Service Manual. I HIGHLY recommend laying hands on one (or a paper and a PDF copy); it'd be one of the first places to check wiring diagrams for things that don't work.

A big thank you for that info, I will definitively try to get that manual. I guess it's just a coincidence my stereo went out or maybe wired wrong.

Well, I'd also check the ground points under the dash (there's a cross member that with age is failing for grounding).
It may be neither is bad, but the ground they use is.
And of course triple check all fuses; if the fuse that runs the 5V Constant fails, most radios will fail; and that's the fuse that runs the time delay relay also. Fuse 14 in the fuse block.

Yeah, I can attest to this. I have a brand new aftermarket radio in my 90, and the other day the Radio quit working. I checked the Radio fuse and was all good, so I tore apart the dash, disconnected the harness to figure out where I lost power. It was the always on battery voltage, although it's 12V, not 5V. In addition to the radio, it runs the glove box lamp and a few other misc items.
What ended up happening with this? I have same issue
