No parking lights or dash lights

This is not a bulb issue. They do not all burn out and the same time. Also, the dash light circuit feeds off the tail/running light circuit, so do not concern yourself with the dash lights. Those will work once the tail light problem is solved.

Besides checking the fuse for the tail lights, check for voltage on both sides of it. Spade-type fuses have two tiny test points on top to take voltage readings. This is fuse # 2, a blue 15-amp in the inside fuse box by the left side of the dash. You should find twelve volts there all the time.

If you do have twelve on both sides of that fuse, the next suspect is the head light switch. You will need to pull that out so you can take two voltage readings at the connector. Back-probe alongside the wires without unplugging the switch from the connector. You should find twelve volts on the pink/red wire.

Next, turn the switch on to the tail lamp position, then check for voltage on the black/yellow wire. If it is missing there, replace the switch.

Oh, sure. Ask me a question that proves I'm not as smart as you think I am!

I left the dealership in '99, just before the PT Cruiser showed up, so I've never worked on one. I DO have two friends with them, but they're out of town so I can't look at them. If I understand what you're saying, the head light switch is on the turn signal switch. That assembly has to be plugged in so it can be replaced. That plug is what you have to find so you can see the wires coming out of it. Typically there will be a two-piece cover to remove, just under the steering wheel. Then, if you can't get to the wires, the switch assemblies are usually held on with just two screws. Remove those screws, then you can pull the switch away to where you can gain better access to the wires.
