I hit the left turn signal again, the signal lit up and afterwards the DRL stayed off, Hit the hazards, turned it back on. I wonder if its anything like when the radio loose's the display or when a PS3 takes gets a YLOD, I wonder if i can pull the DRL module out and use a heat gun on that bitch to re-solder the connections.

If your hazards work fine, but the turn signals do not, then that would indicated that its a turn signal switch problem. There's a connector at the bottom of the steering column where you can test/trace that.

My understanding of the schematics is that the hazards and turn signals use the same relays in the DRL module. So, if it works fine for one, then the DRL module should be good.

I have a similar problem and cannot diagnose it. It's just the driver's side. Replaced the socket and tried three new bulbs, none of which worked. Replaced a fuse, still didn't work. The DRLs work fine during the day, but when I switch on my headlights the drivers side won't blink, and it also won't allow the drivers side tail light to blink.

Your test is the same one as mentioned above. You have to turn on the hazards when all this is going on to localize the problem.

So how can I diagnose it by using the hazards?

Btw OPs rear blinkers still work, mine don't.

You just turn on the hazard switch. If the hazards flash but the turn signals don't, then that proves that your wiring, sockets, and bulbs are all perfect.

My expectation is that your hazards will work fine and you just have a bad thermal flasher.

Right, that's a tell-tale that the OP has a DRL problem.

How hard is a flasher install and where could I get one?

Tested my hazards...

They worked just fine with headlights on and off. But when I turned my headlights on the front signals blinked one at a time...Is this normal? The tail lights still both blinked at the same time.

That's odd and not normal, but probably a different issue from the turn signal problem. I'd go for the turn signal flasher first and see what happens. There are two, one for the turns and one for the hazards. The turn signal one is on the right side under the dash and the hazards are on the left.

Replaced the flasher today... Now the blinkers work with the lights turned on and the lights turned off so that's a plus.

However, the driver's side now blinks slower than the passenger's side only when the headlights are turned on. And the front blinks at a different pace than the tail light. It's very weird. Any idea what's going on? Maybe something to do with the socket or bulb? Even though I changed both.

Did you replace with a new thermal flasher? If so, its normal for both sides to be slightly off, but it should not be noticeable.

On a thermal flasher, the rate of flash is dependent on the amount of current going through the circuit. (If my engineering is correct, more current should heat up the flasher more quickly and give you a faster flash.) This is by design and helps tell you when bulbs are burned out. (If a bulb burns out, your current drops and the flash will slow or stop entirely.)


If the rate changes, when your headlights are on, it sounds to me like you have a short between the parking lights and turn signal circuits. Some things to check:

- With the headlights on, are some of your parking lights brighter than others?
- Have you replaced any sockets on the car before this happened? (Maybe the parking wires and turn signal wires got reversed at the socket?)
- When the headlights go on, does your driver's side slow down or does the passenger side speed up?

The front signals are routed through the DRL, so the blinking will not be synchronized with the rears, but you should still have the same number of flashes per minute.

Yes I replaced the thermal flasher. I will check all of those things tonight and report back to you. I replaced the driver's side socket a few weeks ago, didn't splice any wires. I followed a write up that I believe was on another forum where you take out the wires, clean them and install them in the new socket. I don't think I switched up the wires into the wrong spot but I will check!

I checked them tonight finally. Ok so during daytime drl mode everything is fine, however the drivers side drl looks more whitish yellow compared to the darker yellow of the passenger side..

Also when I turn the headlights on, the left hand arrow stays lit still on the cluster in my dash...this bugs me.

When the headlights are on, the drivers side drl that I replaced the socket on blinks slightly slower than the passenger side. Thoughts?

Sounds like the bulbs are different on each side. If one of the bulbs is the wrong type, it could cause all of these problems.

I'll check these today. Should I go with the ones from the owners manual? I heard some bulbs run hotter than others.. I think I have 3357 in thererigh now but I'll check later when I have time.

Could different bulbs cause the turn signals to flash at different speeds?

Parts lookups will tell you one or two models to put in. As long as they are the same, you can start to debug any issues.

If the bulbs are different wattages, they will draw different amounts of current, which will change the rate at which the thermal flasher blinks.

If one of the bulbs is the wrong model, it can short the two filament contacts in the socket causing odd happenings when you turn on the headlights.

So I finally had time to look at it again today. Come to find out, I had the three wires in the wrong holes in the socket. I should've double checked that before trying to mess with anything else. Put them in the correct order and...whallahhh. Works like a charm.

Thanks wssix99 for all your help and patience! It's greatly appreciated.

Found a new DRL module on Ebay for $30, it said that it was for a chevy venture but it had the same part #. Swapped it out and everything works great now.

Mine is doing some similar weird ****. On the drivers side, the turn signal doesnt work at all, but both filaments of the bulb stay lit. The passenger side signal works, and only 1 filament is lit. What a pain in the ***.
