Daytime Running Lights Won't Work

Ok, here's a change of pace for you...

 

Usually, when it comes to DRLs, most people are trying to disable them. Well, I'd like to get mine back. Don't know what happened to them, made a basic (at least I thought so) maintenance repair, and now they're gone. Here's the background.

 

I've got a 2000 Chevy Suburban 2500 LT, and recently replaced my headlight switch because the dash light control was failing & frequently went completely dark. Swapping the switch was very straightforward - pop off the trim ring, slide out the switch, unplug/replug, slide in the new switch and replace the trim. The problem is, I no longer have DRLs and my headlights are on all the time. I don't have to turn the control for them to come on - the auto on headlights seem to have taken over. I can manually disable them but hitting the dome override button 4x's, but that doesn't do anything for the DRLs & that trick only lasts till I turn off the truck.

 

Any ideas? Is there some special code I need to update b/c I swapped the switch? Thanks for your help.

Yep the ambient light sensor will do that. I've actually pushed mine down into the dash when cleaning, seems like it's spring loaded for some odd reason. If it's disappeared stick your finger down through the hole and see if you can dislodge it, it's probably just stuck on the underside and will pop out.

 

I don't know why people are so averse to DRLs. They're mandatory in Canada and are a great idea because they indicate that a vehicle is in drive and closing speeds may be a lot quicker than you anticipate. I've gone to pass vehicles and nearly had head-on collisions with oncoming traffic that looked like they were parked because they had no DRLs on, or their color just blended with the road.

Repair

 

 

Looks pretty straightforward - I'll give it a shot. Only difference I can see is that there appears to be two sensors on my dash.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because it’s in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
