Turn signal trouble

Turn signal trouble
I replaced my DRL/Turn signal housing last night along with new sockets and came up with a problem. My front passenger light stays solid lit at all times. The turn signal doesn't cause it to blink nor do the hazards. Every other corner of the car works as intended. I checked the wiring and I believe that it is correct for the socket. Any ideas? Would the DRL module cause just 1 corner to stop working and be solid on all the time?
Thanks!
Thanks!

What I used to do is have the bulb sticking out of the housing and wiggle it just a bit to see if it would start flashing, I would never put the bulbs back in the housings until I saw that they would blink. Sometimes it just has a small connection problem with the metal on the connector. Careful with your fingers, those bulbs get hot fast.

I've tried multiple bulbs and it's a new flasher. The hazards do not work either. This one light stays solid the entire time. All other flashers and hazards work properly. I'll pull out the multimeter and see if all the lines are getting voltage to the socket. Just thought it might be something nice and easy to fix

I'm so much more interested now! This is no longer your average turn signal thread.
If one light is solid, your flasher isn't flashing. (If your front sockets, bulbs, and flasher is good and your flasher is thermal, the problem could be at the back of the car.) Here are some other questions to narrow down the issue and other things to test/look for:
- Do your parking lights work properly when you turn on the headlights?
- What happens to the rear tail lights when you turn on the headlights and turn signal? Are they lighting properly and do they stay solid with the front turn signal when its solid?
- Have you checked the rear bulbs to confirm they are all the same/correct type?
- What kind of flasher did you install? Is the new one electronic?
- If you installed a thermal flasher, do you know the model number?
- Did you change the hazard flasher also?

Key in and turned to ON:
Both front DRL are on
Blinkers turned on - all corners flash except front passenger which stays solid lit
Hazards turned on - all corners flash except front passenger which stays solid lit
Turn on parking lights:
All 4 corners solid lit
Blinkers on - All corners flash except front passenger which stays solid lit
Hazards on - All corner flash except front passenger which stays solid lit
Turn headlights on:
Driver side DRL goes out but passenger stays solid lit
Blinkers on - all corners flash except front passenger which stays solid lit
Hazards on - all corners flash except front passenger which stays solid lit
So no matter what state that light is supposed to be in, it just stays lit.

I changed out both turn and hazard with Tridon EL12. Here are the light statuses in the various states:

Hazards turned on - all corners flash except front passenger which stays solid lit

But... since it started right when you re-wired the socket, that makes me wonder. (The DRL module is also a really expensive part to replace!)
When the car is on and your parking brake is set, do the DRLs both turn off?
When you turn on the turn signal with the parking lights/headlights on, does the passenger bulb get brighter? (It should as in that condition both bulb filaments should be energized.)

If this happened on its own, then it would indicate look at the DRL module being bad. (There is a flashing relay in the module that turns the DRL "off" as the circuit blinks since the DRL and turn signal share the same filament.)

Both filaments burn at all times in the bulb except when the headlights are turned on then one filament goes out on the passenger side. The driver side goes out all together when the headlights are turned on. Signals/Hazards do not change this at all.

I'm pretty sure at this point that it is the DRL module. One thing that I did notice today that I never paid attention to before is that when I pull the e-brake, the Brake light never comes on.
Another quirk I did not mention before was that the right signal indicator never came on with the blinker. I thought it might have been because of the dash bulb was out behind it. But today for the hell of it I tossed in some LED bulbs that I am going to be putting in once I get everything sorted out and it would cause the right indicator to come on solid. So that removed my theory about the dash bulb being bad.
Hopefully I can snag one off the parts section for a good deal since I really don't want to shell out 250-300 for this.

My bad, I failed to mention that the DRL/Turn signal on that corner has not worked since I picked the car up last Oct. The sockets were so corroded I am suprised that the driver side worked when I replaced the bulb in it. I have just now gotten around to replacing the sockets.
I think this is OK and normal. If I recall correctly, the cluster light is out of phase with the exterior bulbs. So, when the exterior bulb is on, the indicator is off and vice versa. This is another indication that the DRL module is frozen up.

Your parking brake switch is either corroded or dirty. (Over time, the copper corrodes, belly button hair collects in there, and it will stop making contact.) You can unscrew the switch, pull the copper contact out, polish it up and clean it to make it good as new. Once you do this, your BRAKE light will come on and your DRL's will properly turn off when the parking brake is set.
Is there anyway to replace relays within the DRL module? I am handy with a soldering iron and am no stranger to replacing things like capacitors in electronics.

Yes! I've been looking for a dud module to try this in prep for when mine goes out. (I plan on keeping my car for a long time.) You should be able to crack the module and test the relays. If you do this, please post a thread with pics for people to see. It should be an easy thing to do if a proper relay can be found.
I'd suggest doing a quick fix to the parking brake switch and testing the headlight switch. If you get or confirm those two things are in correct order, you might be able to fully isolate the problems to the DRL relay.

When I get some more time to break apart the inside of the car I will try this to try and narrow thing down some more.

Just thought I would pop in to say that I finally got this mess all sorted out. I had gotten fed up with working on it and let it go for a while and before I knew it, state inspection was due in a couple of weeks. So I bit the bullet and brought it to the stealership to have them give it a look. They ended up finding a wiring short in the dash, a bad turn signal switch and a couple other pieces they said were simply just missing from inside the steering column. Score another one for the half assed mechanic work from the previous owner. But I've swapped in my LEDs and it is now happily shining the DRLs and flashing on demand.
