I just purchased a mint 95' K1500 Silverado the other day, and I love the thing. But I have noticed one thing wrong with it. Whenever I open the doors, none of the interior lights come on. The dome light nor the door lights come on. Also, the Cargo light won't turn on either, with the doors open or dome light on. Now the dome light DOES work whenever I switch it on with the dash button, but not when I open the doors. I haven't checked the actual fuses yet, which I plan on doing tomorrow, but I did look in the owner's manual at the fuse layout and I don't think it's a fuse? The CTSY fuse controls the Cargo, Glove box, Dome, and Courtesy lights, as well as the mirrors. Well the Dome light works, the Glove box light works, and the power mirrors work. It's just that the Cargo light doesn't work, and the interior lights don't come on when the door is opened. Sorry for the long post, but I figured I'd ask here before I started checking it out more myself or even taking it somewhere to have it looked at.

You do know there is a override switch at the headlite switch?

Yes I know this lol. After tinkering around with it some more, I've narrowed it down to the actually Headlight switch being the problem. I believe there is a short in the switch because the override button doesn't lock when you push it in unless you push it really fast. When it's out, I can open the passenger door and push on the button that the door pushes in when you close it and it turns the lights on, but it's extremely touchy. I'm going to order a new switch assembly and hopefully that will fix my problem.

I ordered a new switch unit last night so hopefully it will be in sometime this week. I hope the switch is my problem, because if it's not, i'm going to have alot of fun going through the wiring and testing everything :rolleyes:

I'll second the door pin swithes, if I may. My '97 Silverado would randomly flash the interior light while driving. I was dreading tracing out the wires, but it turned out to be the door switches. Easy fix.

I don't think it's the door pin switches because when I open the door with the key still in the ignition, the buzzer goes off. If it were the door pins, wouldn't they not work for that?

Ok well I received the new headlight switch in today and I put it in. It still didn't fix my problem, so I know it's not that switch. It HAS to be a problem with the door pin switches I guess, or maybe wiring. I know that the driver's door will not make the interior lights come on at all when open, no matter how many times you push the door switch pin in. But the passenger side door will sometimes turn the interior lights on when open, and you can always push the pin in and they'll come on. However if you barely tap the pin, they'll turn off, or flicker like there's a short. Does anybody have any ideas? Or possibly a part number for new door pin switches, 95' K1500.

The door switch is less than $10 from the dealer, and easy to replace.

 

 

How do I get the door switch out? Does the switch pop out of the dash, or do I have to remove some of the dash to actually get in behind the switch?

I've had the same problem. In addition, the lights don't go on when I turn off the ignition. I'd be more concerned if my wife drove the truck more at night. Of course if my wife drove the truck more at any time, I'd have some major concerns!

The door switches are based from ground connections to make the lights work. It's possible that the door switches are not contacting ground or some contaminates are keeping the contacts from connecting. Make sure that both the body and engine have ground straps to the frame.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
