On my 2004 Suburban Quadrasteer ( just bought ), when it switch it to parking lights, they don't come on in this position unless I push in the button for the fog lights. According to the owners manual, the parking lights should come on reguardless of the fog lights. Is the switch bad??? Also, when I bought it, it has a remote start on it ( Avital brand ) that I don't need. Is this somehow maybe affecting the operation of the switch??? Please help...

The parks lights should come on at any time with the switch, the command start could be causing the issue. I have found most command starters poorly installed. However, looking at the manual, it could be many things, I would not just throw a switch with out some diagnosis. HTH

My 2003 Yukon XL Denali does the same thing, but the dealership told me that it's because it was a Canadian truck and all the lights were controlled automatically with the light sensor on the dash. In Canada, DRL's and headlights are mandatory throughout the day, so there's no option to override this "feature" by switching on the parking lights. During the daytime, if I wanted my parking lights on, I had to hit the fog light switch too. I bought the truck anyway because it didn't bother me to have my lights on all the time. Oh, and I don't have a remote starter (yet).

 

Easiest ways to tell if you have the Canadian model truck is if you have a sticker on your front passenger side window that says "Les objets dans le miroir sont plus proches qu'ils apparaissent" (or something French like that), if your rear air temp controls by the sunroof are in Celsius, not Fahrenheit, or your owner's manual has a French translation in the back.

 

 

 

Find out if you have a Canadian truck - you may not have any control over your lights if it is.

No , my truck was built in Texas, home of trucks I'm told. Someone out there must have an answer to the parking light issue. You shouldn't have to put the fog lights on to make the parking lights to come on. Is there a GM technician out there with an answer...hope someone can help

I am a GM Technician. The park lights should turn on when you turn on the switch even with the fog lights off. Based on your complaint, It is difficult to determine the exact problem with out hands on diagnosis. It could be a wiring issue, it could be a fault in the BCM, and it could be the switch. If it was my truck, I would not start throwing parts at it without diagnosis, but its not my money!

I'm in Canada and my truck doesn't do this....I do have a 2002, so perhaps it's different.

I do have DRL, but they are a seperate light from the headlights/tail-signal lights and fogs.

 

I can turn on the tail lights uisng the switch in the day-time and they will come on...independantly of the fog lights.

 

The bulbs in my DRL lights are burned out, and I haven't bothered to replace them yet. I often turn on the tail lights during rainy days, without the fogs.

      Valvoline R&P Fuel System Cleaner

      By Grumpy Bear · Posted

      Okay boys and girls I put a bottle of this in Dizzy the oil burning guineapig after a tank between the coil and plug service of the #3 hole and near the end of the first R&P 5W30 attempt. As a note I did a two R&P oil changes back in October of 2025 with little effect. Granted they were 1K mile a shot oil changes so.... Then followed by fourteen  1K mile changes of Mobil 1 Euro 5W30 FS. Also ineffective.    Anyone who has followed the adventures of Dizzy may remember that to put the oil on the full mark of the published nominal 5 quart change I withhold about a cup of oil. That over the last 50K miles the P0420 light has been a frequent flyer, sometimes three of four a day. And that even on 93 octane fuel she registers some KR even in moderate conditions on favorable days on slight inclines. Lastly when giving her a kick in the pants, something done about once a week, she looks like a diesel with the pump turned up. 😬   After one bottle and over the last 500 miles of a 3K mile OCI, of the first oil change I dropped the nastiest looking oil ever in her history. That's saying something as  you will recall I have used AutoRx, HP EC30/40 and a few other harsh solvents in her before including the GM top soak twice. This was syrup. Black stinky, inky syrup but the filter wasn't all that bad.    On the second fill I had to use the entire 5 quarts to reach the full mark. That was unexpected! The ignition KR is completely gone! Even at 99% engine load. MAP is much lower. Level road is now 9.8 instead of 12.5. Fuel economy is remarkably higher and for the first time since her earliest days she will spin to 6500, more than a thousand higher with out laying down dead. Yes, the coil and plug had something to do with that but remember the first 2500 miles after that repair on the first change it was same ole same ole Dizzy. Seems we have top rings that are somewhat functional again. P0420 code only comes on now if run in town for more than an hour of stop and go. On the open road it goes weeks without a incident. Perhaps it is cleaning the cat on the pass through?  Fuel Trims have improved as well. Nothing not to like.    To early to say about oil economy but the changes to date in the operational aspect is remarkable. I can't think of a worse case than Dizzy.... It's already paid for itself in a few tanks of fuel with the mpg improvement.    @OnTheReel, I'd say if the Jeep didn't respond perhaps there wasn't an issue to respond to.    I've run the Red Line SI-1, AMSOIL fuel cleaner, GUMOUT and Techron all in this SUV without any such results. Color me impressed. I'll be running out my supplies of the list mentioned and moving on to the Valvoline R&P Fuel System Cleaner.

      first oil change - 2026 2500HD gas

      By Homer1959 · Posted

      Hey Chuck !!Thanks for the all the info I'm an old fart and I have everything I need for the oil change at home,minus flexibility .... and I’ve been doing my own oil changes for 40 years. I just didn’t want to end up without a crush washer or with the wrong one in my stash and have to walk to the auto parts store, lol. I climbed under the truck to check the location, and man, it’s going to be the easiest oil change and filter swap in the last 40 years—right up there with my 2014 Mitsubishi Outlander 2.4. No mess, nothing to drip on—just perfect. I’ve got one more free oil change to use, and then that’s it with the dealership!

      2027 3.0l - ordered

      By Atlas · Posted

      I think this subforum was created for the new generation pickup trucks (2027-) with the 3.0 but I don't think it's a big deal either way. There are probably 2027 model-year specific changes for the SUV's too.   I was just curious if you had issues with your 2025 3.0. I'm still under 10k miles on mine and fingers crossed I don't have thrust bearing issues. I'm guessing not, since you're willing to buy another one! It's a good engine minus one or two manufacturing whoopsies.
