Right front turn signal not working
On the 80.
All of the other turn signal lights work except for the right front? The rear right works?
The bulbs are new, the Flasher is new (replaced with the electric Flasher not the mechnical), fuse is new.... head lights come on, just not the turn signal. I took a test light to the front lights while the right turn signal is on, and the teat light didn't come on.
Past weekend I jumped interior light courtesy unit that is rigth of the glove box (just jumped the two white leads); I don't think this would have done it thou

When I turn on the left turn signal. I can hear the Flasher click twice, but when turn it rigth, I only hear a signal click. Does this mean the Flasher is bad? Or is the Flasher working OK?
Was under the dash listening/looking around....

Sometimes the wiring looks good but the ground in the socket goes bad.
Attach a wire to a good ground and touch the wire to the socket as shown:

Are the retaining pins (protruding posts on the side of the metal bulb case) in line with each other or are they 'staggered'? If they are staggered, you might have installed the bulb 180* around from how it should have been installed. Otherwise, the "new" bulb could be defective [in happens] or you could have a wiring problem on the power feed wire or on the ground wire.
You can swap bulbs to prove that it is not the bulb (or find out that it IS); and you can use a simple jumper wire to make sure that the lamp has a good ground connection.

7T1vette, the bulbs are not protruding. could the Flasher go bad for just the one turn signal?
really weird since when I turn the indicator left sounds like the Flasher is clicking twice. when I turn it right it clicks once.

I tried connecting a ground to the bulb and didn't work.
I see there is signal coming down the column into the harness at the base of it. I tested both sides with a test light on the blue wire.
the hazard lights come on for all corners of the car only time the marker and turn signal dont come on is when the right turn signal is turned on. what gives?

Hi again,
Your turn signal bulb is #1157, it has one high pin and one low pin so it only goes in one way.
Power for the right turn signal comes out of the turn signal switch on the "J" connection at the harmonica connection.
With the key ON and the turns signal lever set for a right turn see if you have 12 volts on that blue wire.
PS:Good news:
Jumping the two whites at the delay only eliminates the delay feature and does not affect the turn signals.

The front signals and rear signals each have separate contacts in the switch. The rear working doesn't really mean much since the contact that turns-on the front might be bad.
The hazards working but not the turn signal is pointing towards the switch. But, it could be the wiring under the dash too.

A flasher cannot cause one side to work and not the other. Neither will fuses or headlight switch, or anything else that provides voltage to both sides. You need to trace the wire back from the socket and find at what point you are losing it. Most common would be at or in the bulb, but after you eliminate that, go to the socket and then work back toward the turn signal switch. Just the fact that the bulb is new doesn't mean it can't be bad.
EDIT: Just saw your post about the hazards flashing that bulb. That would eliminate grounds, bulbs, wiring at the socket, etc. I'd do as suggested and check the output of the turn signal switch wire going to the right front bulb.

It won't be that easy!
That's interesting!
If you have 12 volts on J coming out of the column, then try applying 12 volts to the other part of the harmonic connector.
If the light blinks your problem could just a bad connection at the Harmonic connector.
