Daylight running lights not working

[hot_sd]

This is for a 2000 metro but hopefully it will work for a 99. If the images does not show up clearly PM me your email address and I will send you a higher quality PDF of the scan.

Thanks, That IS the same circuit as on my '99. It looks like I'll check to make sure there's voltage at terminal 1, the red and white wire going into the connector. If that shows voltage when the DRL is supposed to be functioning, I'll know the controller is shot.

I am having a problem with my 1999 silverado. The headlights stay on but the drls don't work at all. Can I remove the fuse drl fuse to switch off the headlights and just use them manually?

try it and see!

sas95 has a lot of good inpute here. I think he'll be a valuable asset to the AF. Hopefully he can help me too. I have a 96 Metro with a headlamp issue too.

1. With my headlight switch on in head position and parking brake off, I have all lights except the headlamps.

2. With my headlamp switch to the off position, I have headlamps only, when the parking brake is disengaged and low beam only.

Does this indicate my DRL control module could be toast?

Update:

I just replaced the DRL Control Module and the Diod and still have the problem

[leonbentz]

Well, I just replaced the combination switch and sure enough, I have head lights now. It turns out, my DRL has always worked fine. They are supposed to run in the off position. My head light portion just quit. High beams and low beam selector works too. One thing I noticed too, is the plug, from the combo switch, that mounts in the fuse box (closest to the firewall) has a lead that gets hot and melts the plastic a little. You won't have any trouble spotting it, if you look for it.
If this is a full time hot, then I'm going to run it separate from the plug and install it's own fuseable link. This may possibly be a reason why my headlight switch nuked out.

so does this mean you have a spare DRL module you may be willing to part with? Is it silver with 8 pin connector?

[leonbentz]

No, mine is black, with 11 pins. The number on it is: 38660-60A01 which is a bit different than the ones earlier in this thread. Mine is a '96, rather than a '99. The '95 and '96 had the sealed beam headlights (versus composite), so the wiring diagram will be different, than the 97 and later. For all those out there, who may need a combination switch, the same rule applies, as with the DRL Control Module. Good Luck and ask questions if you need. I can possibly help.

Oh yea, I follow you on the Haynes issue. Mine didn't help me either. I just started replacing the cheapest parts and went from there. I venture to guess your DRL cm is toast, from what you're describing. Go to a wrecking yard and pull one. You should be able to get one for about ten bucks.

Sorry, I missed the part about your's being a '96. I went to a u-pull it yard and they only had one metro and it was a '96. Of course it had the 11 pin connector and the black module. I was able to take a bunch of parts off, but not the DRL module. I'll keep looking.
