Default [turn signal] Issue with passenger side.

Issue: Passenger side front turn signal. Drivers side turn signals work fine. Passenger rear signals both work fine..they just blink fast.

Problem: Worked...didn't...worked...doesn't today

What I've tried:
1. The hazard button trick (turning on and off)
2. Replacing the bulb
3. Checking fuses
4. Checked for thrown codes

What I need: Help!

You've done the obvious already. Start by finding out which bulb is not flashing when you have the blinkers on. Normally it is the hazard switch as you know, but its possible the headlamp switch assembly could be bad as well. If its a front lamp not flashing, then check the ground packs on the forward frame rails adjacent to the hood risers.

check the socket... The bulbs can casue melting of a small hole in the lens housing. This lets water in which can short/corrode the socket.
I have had to replace both my front sockets.
GM wants $70 for a socket and pigtail.
lowest cost place to buy the original is www.rockauto.com

I had this happen I believe a few years back my memory is failing me however.. on a customer car, a 00 c5 coupe It turned out to the the multifunction switch.... Get a wiring diagram and start tracing the wiring from there. When you hit the right wire, with a test light, the test light will blink.

So stupid me...I had my running lights on and realized "wow..the passenger side one is DIM!"..so I ran codes and came across this

40 BCM B2583 H & C...so it was a history code and is now a current. I'm aware that it is low voltage to the turn signal..but how the frick do I fix it?
