Check right next to H. Here is the list of both plugs for each headlight, with wire colors.

"I was a firefighter for 30 years" sounds like a qualifying statement.. if not intended that way, my mistake. And I never said you were evil. I clearly stated "everyone should be free to choose if the

Why? They're for safety. Not sure if you've ever seen the result of a head on collision... I bet you would change your tune if you did.

I'll take paying for a bulb over getting smoked by someone that isn't paying attention any day. Lots of people are too clueless to turn on their headlights in low visibility conditions.. I personally

i checked on the bcm side of the connector and failed to see the DRL specific yellow wire. my thinking would be that this slot would be reserved for the sierra DRL seeing as they are separate drivers from the lowbeam bulb.

I have a Sierra SLE which doesn't have the LED DRL's. The Sierra uses high and low beam in the same bulb. So, I'm wondering if the BCM is different than the Silverado???

Does anyone know if you install an aftermarket HID kit, if the DRL feature would be bad for them...the constant on, off, on, off if you turn them off immediately after they turn on after being shifted into gear? this is the only thing that is holding me back from getting a DDM kit.

I wonder how difficult it would be to disassemble the headlight switch and remove the spring feature that prevents leaving it in the OFF position?

Was pretty easy to do on my 2015.

i wanna disable the auto lights to..haha

Did you ever figure out how to disable the auto lights? I have an SLT Sierra, so I'm fine with running lights or leds always on, but I have an hid kit in there and the auto feature is way too sensitive. Even when its not very dark out and I unlock my truck the headlights come on, then I have to wait for them to go off, then start the truck and they're on again. Going to kill the hids.

 

Is there at least a way I can disable the headlights from coming on when I unlock the truck when its 'dark' enough out to trigger the auto function

The unlock lighting should be able to be disabled under the vehicle configuration menu under "approach lighting".

So, no one except for Chris White can disable the DRLs/automatic lights? it is total b.s. that Chevrolet service departments will not disable them via the BCM. The federal laws were changed in 1990 so that GM could sell vehicles in the U.S. with DRLs and automatic light features. There are no laws within U.S. borders stating we are required to have DRLs or automatic lights.

It's not that they won't, more likely they can't. The diagnostic tools dealers have aren't magical. If GM doesn't want it messed with it won't be changeable.

Am I missing something here. I just switch my light switch position all the way to the left (off position setting) and all lights are off.

yea but like stated above its spring loaded, so once its put into drive the drls come on no matter what..

 

interesting point about removing the spring in the switch..still wouldn't turn off the drl though..thats gonna take some wire harness or bcm work..

 

im getting resistors this week to do the auto headlights but still have to figure out the drls..

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
