Ahl/drl ?

The AHL and DRL


I have a 4.3 V6 2002

The AHL/DHL what is it?

What will de-activating them do for power?

And where are they located?

Shouldnt make a difference power wise...the DRL's are under the hood...the AHL you have to have a resistor for, and its that little black knobby thing that sticks out from your passenger side speaker grille.

they will not make a difference power wise....


*note: the following works on 99+ s-10/sonoma/blazer/jimmy*

<center>DRL</center>
<center>Daytime Running Lights</center>


there are two ways to do this. either way, DO NOT MODIFY PINS 87A OR 30!!

first, remove the cover off the fuse block in the engine bay. locate the relay for DRL, then do one of the following.....

1.) bend one of the prongs up and reinstall the relay.
2.) cut the other three prongs out and reinstall the relay.

once relay is installed, be sure to double check your highbeams, make sure both work. those are contolled by pins 87a and 30. that is why it is critical not to modify those two pins.


<center>AHL</center>
<center>Automatic Head Lights</center>

you will need a 2.2K Ohm 1/2 Watt resistor. these can be found at Radio Shack for about 50 cents for a pack of 5.

remove passenger side speaker grill on dash. unplug wire from the light sensor (little ball sticking up from the grill). insert resister into plug, and use a zip tie to strap the plug down to the dash. reinstall grill.

i pulled the fuse for the DRL in the fuse box on my 95 but i dont have factory fogs. i heard if u have the factory fogs it wont work cuz they run off the same circuit or something. my fogs are aftermarket on their own switch fused in-line not through the fuse box

Do both of your Brights work? I pulled the DRL fuse and only one bright worked

I have a 2000 LS and i pulled the fuse under the hood and cut the three prongs off (leaving 87a and 30) and my DRL's still work. High beams etc all work too. I removed the entire fuse (just pulled it) and everything still worked. How can they still work with NO fuse even in? The dome thing works, hit four times, but I want a perminent solution. I have installed silverstars and it looks lame with DRL's on. Please help.

bigboz's98zq8 i have a 98, i bent the prongs on the drl relay under the hood and put in the resistor in the dash for the AHLs. the factory fogs work and so the high beams no problems.

This problem was a result of me overlooking the numbering setup of the fuses. I now know the numbers are actually above the fuse...not below it. I ended up pulling the wrong one. Haha. I expect to get a few laughs outta this one, but I'm still learning so its all good. I'm just glad i fixed this problem and my drl's in all of two minutes =-)

I'm not sure which year S10 you have but to disable your daytime running lights you do not have to cut, bend, or splice any thing if you have a newer S10 made in the US. If it was made in Canada the tip I am about to give you may not work....

If you have the type of light switch with a dome light overide switch (push button) there is a tech mode built into the switch. start with the switch in the overide position and then push it in 4 times sequentially. You should here a "Bing" sound and then the DRL's will turn off. To turn them back on simply push the button 4 times again and you will here the same "bing" sound again and they will turn on. The reason that some Canadian made trucks will not do the tech mode is that the switches were contracted out overseas and no tech mode was included. It's also the law in Canada to have to drive with your head lights on in many of their provinces. Well I hope this helps out and I hope noone has cut any wiring they didn't need to.

PS: For those who have the Canadian built S10's that do not have the tech mode you can try and depress your parking brake 1 click, just enough to disengage the DRL's activation switch but not enough to engage the brakes.

'03-bent out prong 86 for DRLs, reinstalled, worked perfectly (with my luck i should probably add...SO FAR...). Not worried about the AHLs, if they ever bother me it's not that hard to hit the dome override 4x. I was wearing the crap out of that little button for the DRLs though.

My friend has a 98 blazer, I have a 98 s10. I have been trying the dome over ride thing for a few weeks now with no success. He figured I'm a gimp so came over to show me how to push the botton "the right way" but it didn't work for him either. However, on his truck it works great. From what we can tell, there isn't any difference between our two trucks, except for the fact that my headlights are always on. How do I tell if my truck was made in Canada or the US? Because it sounds like that might be the difference between the two trucks at this point.

Thanks

Yeah. I have a 2.2L that I think is made in Canada (i think this since when looking at engine parts inside I will occasionally see "made in canada")

My DRL lights turned off by bending #86 pin on the relay but I think something got screwed up and now my HEADLIGHTS wont turn off.

hmm... I didn't realize there was a difference between the two... I got the truck used, maybe the previous owner tinkered with that... When I pop the parking brake, the headlights come on (day, night, doesn't make a difference). The switch is in the 'off' position, but that doesn't matter. Basically, my light switch is useless. The lights are always on with the same intensity, no matter what position the switch is in. When I go under bridges or through tunnels, though, I hear a click, and the interior dashboard lights come on (from that sensor in the speaker, I'm assuming). Another thing I noticed, which may or may not be a problem, is that my brights don't seem all that bright at all. I actually prefer driving with just the headlights on. I checked the fuses and they are all still there, and the relay doesn't appear to be tampered with, so up until now, I just assumed this was because the previous owner installed those super white/blue lights. Anyway, thanks for the info. I'll keep looking.

ok, i looked in my owners manual and found the drl relay location under the hood. but when i pulled the relay out, it had numbers (1,2,3,4,5) no 87a and what not. and it was like half the size of the type of relays used in alarm installs. what's up with that? I don't know which posts to bend! can someone help me out?

I have a 2003 ZR2.

I can disable the DHL's and the auto-on's simply by
pushing the dome over-ride switch in and out 4 times
in succession quickly. In-Out-In-Out and then you will hear
a "ping". The DHL/Auto is disable until either the engine is
turned off or the button sequence above is repeated.

My relay is also numbered 1-5, am I stupid and overlooking something? Could someone post a picture of the relay and point out 87a and 30?
