Anyone else notice the ambient light sensor kicks in the headlights way too often  with way too high a sensitivity?

 

I find just going under overpasses and evening drives when the sun is on the horizon, my light turn on. Considering I leave them dim at night it basically means I can't see my gauges in the evening.

 

Anyway to change it?

yes I have noticed this also, way to sensitive. I pull under my carport in the day and my lights come on

Yes, my lights seem to be very sensitive (they have come on when parking under a filling station awing in complete daylight).

Yup! My 17 All Terrain is definitely different in sensitivity when compared to my 15 Silverado. Car ports, underpass', even an hour from sunsets will cause the lights to kick on. Its rather annoying since I have to keep toggling the cluster brightness every morning. Don't like being blinded at 3am when I hop in to go to work. The 15 Silverado definitely didn't have this issue.

I believe there is an option for how long before they kick in. 30 seconds 60 seconds or something like that.

My 17 does the same thing,,,bright sunlight and they will come on if the sun is not shining directly on the sensor, complained to the dealer, he just said that the sensor was very sensitive and it was normal,, In other words,, just put up with it,, My 16 did not do it.

Are you thinking of the delay before the lights turn off when exiting the vehicle? 

 

Exit lighting can be set to 0, 30, 60 or 120 seconds. 

 

Only reference I recall regarding the switch from day to night mode is that it will switch after "a slight delay".

My 15 did not do this. My 17 does. I am so tired of the excuses and reasons the dealership can come up with. This is how I fixed it. I removed the sensor. Google how to remove.  I then took the sensor apart. There are two clips on either side of the sensor. Push them in at the same time and pull the cover off the sensor. There is a white GOOP that covers the photo cell. It is supposed to diffuse the light. I removed almost all the GOOP. I left a very small amount about the size of a baby aspirin. Put it all back together. Now my lights come on and turn off when they are supposed to. It took me about a half hour. 

 

PS. This worked for me however I live in a mostly rural area and although  I do drive under some street lights I was wondering if driving at night in a bigger city if this may turn the headlights off

 

PLEASE Proceed  AT YOUR OWN RISK.

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
