I have a 2003 Gmc Sierra my reverse lightsn and dome light arent working I checked all the small fuses under the hood and by the drivers door they seem to be good. Does anyone know if the reverse lights and dome light are on the same fuse, if so what is the abbreviation on the diagram so I can go right to that fuse. Thanks alot... I got snow coming tommorrow and its pretty hard to plow without reverse lights. Thanks

I think the dome light may be on the same fuse but not totally sure. For starters replace the fuse that controls the back-up lights. I have had more than one time a fues doesn't look blown but in fact it was. i would go to the fuse box with a cheap test light and check that you have power going to the fuse. I also plow here in Maine - i had one time that some how I manage to get the truck backed way into a snow banking and ended up with a light wire being broken and grounding out on the frame. Start with a new fuse and go from there.

I am having a similar problem but the dome light works except for the two side lights on the dome light. I have an 2006 crew cab. On the center dome light there are two other lights that come on when you push the switch. These are not working. Is there a fuse just for these lights?

 

 

thanks

What I usually do to find a bad fuse. Get a 12v test light and probe all the tops of each fuse. there should be two metal terminals exposed on the top of each fuse. If you get no pwer on either end thats fine also if both ends light up your good. What you are looking for is if one end of the fuse lights up and the other end doesnt. Idk if you guys already knew this trick, comes in pretty handy for finding fuses quickly if you dont have the owners manual.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
