Adding Fog Lights to 2015 Sierra W/T

Has anybody added fog lights to the base model Sierra? It has black covers in the front bumper for them, but no lights. Can they be added to the factory wiring or do you need to start from scratch. I've already installed a Morimoto HID kit in the crappy stock headlights, but I could use some more light on the sides for turns.

Not plug and play. The underhood fuse block does not have the correct printed circuit relay, and none of the lamp wiring is there, and the BCM can't be reprogramed to have them function either. Gotta go with a remote switch, and wire a power and ground for them. You can still use the stock housings, lamps and pigtails, but the wiring from the pigtail to the rest of the way is gotta be fabbed up.

This will be the same process as adding any type of auxiliary lighting as it is not plug and play. Are you planning to use factory fog lights? If you are I do not know if you will improve "light on the sides for turns".

Crappy halogen headlights on the 2014 and 2015 Sierras is a well known fact all over this forum. That's why they switched to LEDs in 2016. These things are invisible at dusk and not a whole lot better after dark. GM should recall them for a fix before they lose the impending legal action.

I guess I'm glad I got a '13 then, the head lights in this Sierra just smoke the old Cherokee I was driving previously. So well in fact I'm not going to bother installing the fog lights.

I found a fog light retrofit kit from Winjet that includes the wiring harness, lights and surround bezels, and a factory look dashboard switch bezel. The lights are like the cheap factory ones but I think they can be switched out for Morimotos and still fit this harness.

 

One major problem I've run into is removing the the stock fog light block off plates. They each have four 7mm screws only accessible from the back side and they are a total bitch to remove and replace without removing the bumper. Removing the bumper looks to be an absolutely daunting task. This thing looks like it was designed by a fastener manufacturer looking for early retirement.

 

Has anyone voluntarily removed the front bumper on a new Sierra? What is the easiest procedure?

Did you end up adding the fog lights and how deep did you have to go?

      OCI, not when but why?

      By Chuck FB · Posted

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
