Passenger drl / turnsignal light not flashing the light works in the DRL mode correctly
and when you use the Hazard button all lights work fine.
however to just use the turn signal the rear light goes solid
as does the indicator in the dash
but no flashing upfront in the DRL/Turn on passenger side
drivers side works correctly.....
I have put in new bulbs and it appears that the socket isnt corroded
however the plastic is darkened.
Any ideas?????

tempermental socket I guess.. could be something as simple as that (i.e bad connection) but check to make sure both filaments are still intact.

Mine was doing the same thing.. I though one of the filaments was blown since its a 2 filament bulb, but after taking the bulb out and simply putting it back in, it fixed the problem tempermental socket I guess.. could be something as simple as that (i.e bad connection) but check to make sure both filaments are still intact.

If the DRLs and hazard flashers work properly then the bulb, socket and wiring are okay. The problem is either in the turn signal switch or the DRL module.
It is fairly easy to test these things with a test light or multimeter. Remove the radio so that you can get at the DRL module behind it. You will find two connectors. In one connector there will be dark blue, dark blue with white, light blue and light blue with white wires. These are the front turn signal wires. The white striped wires are the input from the turn signal switch and the solid wires are the output to the front lamps (dark blue for right side and light blue for left side).
Turn on the ignition and right turn signal then test for flashing power on the dark blue with white wire. If there is no power there then the turn signal switch is the likely source of the problem. If you have flashing power then check the solid dark blue wire to see if the power is going through the DRL module and out to the lamp. If not, the DRL module will have to be replaced.

To clarify
All hazards work, and DRL's work
front and rear passenger bulbs both light but dont flash.
so i need to follow your post and should be back in biz.
Anyone know what the DRL part number is for GM,

Both the turn signals and hazard flashers use old fashioned thermal flasher modules that make and break the circuit (flash) based on the heating of a bi-metal strip due to current flow. This design is similar to the way household thermostats work. A non-functional bulb (either burned out or with a bad connection or corroded socket) reduces current flow to the point where the flasher never breaks the circuit so the lights stay on without flashing. The hazard flasher is controlling twice as many bulbs so the loss of a single bulb still leaves enough current to flash the rest.
In fact, using the hazard flashers is a good way to find the problem. Turn on the hazards and then walk around the car looking for the lamp that isn't flashing properly. It will most likely be the front one on the side that doesn't have working turn signals. The front lamps on f-bodies tend to get water penetration causing burned out bulbs (cold water hitting the hot bulb) or corrosion.

All of mine seem to flash properly with the hazards on, and the left turn signal works properly. The right turn signal is not flashing and stays on steady in both the front and rear. Can it be a bad bulb or socket if the DRL and hazards are working/flashing properly, just not the right turn signal? Sorry for repeating my questions, I'm just trying to understand this and I appreciate your input WhiteBird.

If your DRLs work fine, your parking lights work fine (when the headlights are on), and your hazards work fine, then the problem is probably your turn signal flasher.
The left and right sides of the car have different lengths of wire from the flasher to the bulbs. This creates a difference in resistance in the circuit, which can cause the thermal flasher to behave differently between the left and right. That being said, I'd expect the left side to act up before the right.
Short answer is to try a $2 flasher and see if it corrects the problem before getting in to a DRL module change. You need a 323 flasher or need to spend more $ for an electronic flasher in order for things to work properly. (I've found that Napa is the only place I can get a 323.)

so this is a problem i need to contend with....
My Hazards work fine
only one turnsignal works and one is not flashing
I am confused though after reading the updates,
do i have a DRL issue or a flasher issue?

just have to pull the lower dash plate held up by 4 screws
I did the same thing, Auto Zone didnt have the wagner or any 323
so i upgraded to the FL32 Electronic model which is the cross referenced part
its a little faster and louder than before but its working correctly
