Look at the actual filaments in the bulbs when you turn on the blinkers. One should be on for the park lights and the brighter filament should go on and off with the flasher.
I just went through this with my car and found that on one bulb the same filament was acting as the park lamp AND the blinker. It turned out to be a miswire in the socket on that side.
It caused some weird symptoms in my dash turn signal indicator and turn signal circuit.

Greg,
Will check them out, thanks.

I recently revisited my parking light/turn signal issue. I've been running it with it working as before since I don't drive it much at night anyway. Anyway, when I put the bulb in reverse of the way it should fit then everything worked correctly. I then cut and spliced the wires opposite of the way they were then it started blowing fuses, ??? Now I don't have parking lights at all even when it doesn't blow the fuse, and I only have the one turn signal that will work, (the one I didn't switch. Any ideas? I thought switching the wiring like Latech said would solve the problem, now I seem to be in deeper!

If the hazard lights all work, then that tells you all wiring is OK. I would suspect the turn signal switch contacts or wiring connection at the switch. Check that first. You can easily check if ground is an issue by touching the bulb housing or socket ground with your test light. If the light works at all, or the bulb gets brighter, the ground isnt very good. I think the bulbs should light up, no matter what way there are in. Power and ground, they will light. That's what is odd, if the hazards worked normally, that tells you all is connected and working. So that leaves your turn signal switch to be a suspect. Be sure the bulkhead connector is good and tight. If you loosen the bolt and wiggle it, see if anything comes to life. its easy to get a bad connection there, but again, if the hazards worked, then it should be OK.

I thought turn signal housings where plastic, on 69 birds, and the light sockets had three wires coming out: turn, park, ground......????

Could just be my memory failin'.

BUT, if I'm not losin' it, sounds like the car has the wrong light sockets.

I have headlights, 4-ways and turn signals, but no parking lights or dash lights now, and all fuses are good.

[Sport69]

Turn signals still acting the same though. Could my issue with the parking lights and dash lights be the headlight switch?

It's possible..BUT

First check the tail light fuse and make sure it has power on both ends and the clips that hold the fuse in.

[Sport69]

Has 0 volts on the right side of the taillight fuse and has 12 on the left side?

[Sport69]

By the way my 4-ways all work. Does the headlight switch feed the right side of the taillight fuse? If so then I believe I may have a bad headlight switch.

Power goes through the tail light fuse then to the head light switch.

Power on one side of the fuse but not the other...is a bad fuse.

[Sport69]

Fuse is good!

Looks good and being good is two different things.
The little strip in the middle doesn't have to be blown out for a fuse to be bad.
Now a days you see lots of fuses that the strip doesn't get soldered good in the end caps. Brand new and don't work.

X2, if fuse was good, you would have 12V on both sides. take fuse out and check with Ohm meter, or just replace it. Sounds like bad fuse.

If fuse only has power on one side....its bad, no question. Ohm meters are ok to check fuses, but not the best. When the fuse is inline, that puts enough load on it to check it. I had a fuse check good with a ohm meter, but put a load on it, it was bad, although it looked ok. I checked it because it was not "blown" and looked OK, but power would not flow through it.

[Sport69]

I'll replace it and see what happens. Thanks for all the replies, this forum is the best!

[Sport69]

I've tried 6 different fuses and I get the same result, this has to be something else. Are you guys sure the headlight switch has nothing to do with it?

["QUICK-SILVER"]

Battery power goes through the tail light fuse first. Then to headlight switch. The headlight switch distributes power to front and rear (park/tail) lights and instrument light fuse that then goes back up to dash lights.

Headlight switch off, the tail light fuse should test good for power on both ends.
Of this I am positive.

Headlights, turn signals and hazard lights have seperate power supplies from the tail/park lights. The headlight switch is suppose to have two power wires going to it, one for headlights and the other for tail/park lights.

Check some more and post back what you find. Not sure what you've got going on, but it ain't anything that can't be fixed.

What result? Is power going through the fuse? last I read, you had power on one side of fuse but not the other? Power has to get to and out of the headlight switch. What color wire comes out of the fuse panel to the headlight switch and out to the tail lights?

Don't know on the OP's car, but, here's what it's suppose to be: brown/white from fuse box to switch and brown from switch out to lights.
