chris

 

i looked into my owners manual and the relays it lists are these....im thinkin maybe its relay 306, delayed accesorry relay.. anybody have any ideas?



Relay:
301 — Front blower motor relay
302 — Powertrain Control Module (PCM)
relay
303 — Fuel heater relay (Diesel engine
only)
304 — Heated backlight relay
305 — Trailer tow battery charge relay
306 — Delayed accessory relay
307 — Starter relay

 

What year is this truck?

Are you sure the dash dial for brightness is turned all the way up?

I'm looking at a an '05 schematic, and I don't think relay 306 is going to fix it. But no matter what I think, it's easy to swap a relay and see. But the delayed accessory relay is what keeps your radio and window switches live for 10 minutes, or until you open a door. Not really related to dome lights or cargo lights, which only stay on for a few seconds after you close a door.

Unfortunately, I think that is a function of the instrument cluster.

 

Yeh well after thinkin about it I realized I should check to see if the bulb is burnt out.... And there was not even one in there haha.

I did notice that the contacts that hold the light in place only had 3 prongs, so I'm guessin one broke off... So therefore no light bulb.

 

Lots of guys pull those bulbs to stay dark at night. Other times they are pulled because a door switch is sticking and the dome light stays on all the time. So don't be suprised if you install bulbs and then find out that the light won't go out. If that happens, then search for the door ajar switch fix.

 

Thanks for the help
