I am trying to grasp this problem so here are my questions:

With the headlights/parking lights off

1. When using the blinkers, do the rear and front left and right turn signals still work even when the dash indicator is not?

2. Does the hazard switch work correctly and flash the dash indicator, the hazard switch, and the turn lights?

4. Does the hazard switch work correctly and flash the dash indicator, the hazard switch, and the turn lights?

Here is what I am thinking. Could be a bad flasher, miswired hazard switch, bad turnsignal switch, or a bad ground on the lights.

Since the dash flash indicator does not work when you turn your parking lights on, that sounds like a bad ground (most likely in the rear lights but could be upfront too). But in that case, I would not expect to see those turn signal bulbs working when the dash indicator is not.

I would start by grounding the rear and front light housings. In the rear light housings, there is a terminal on each bulb socket to run a chasis ground. Make sure the bulbs are not rusted into their sockets. Sand the sockets if necessary.

If that doesn't get it you will want to check each ground wire on the front signals with an ohm meter to ensure grounding.

I wouldn't do anything else until I checked this first. Its a simple fix, and I have not had a bad flasher, turn signal, or hazard switch yet. But I have found plenty of ground problems.
