The amber light in front is a double filament bulb that sometimes fails and makes a circuit to ground. Does your turn indicator work?

Have you been to visit the Ogre?

My car sat for a long time. The marker lites didn't work at first. I had to clean all the contacts in the sockets and on the bulbs with emery cloth and contact cleaner.

no turn signals either some bulbs in the back are dim too

It will be a good deal for someone who knows how to fix it.

^ and for someone with more patience for an inanimate object.

Side marker lights aren't double filament. They are the same bulbs that go into the courtesy and instrument panel. Do the marker lights illuminate with the parking lights on? If so, then you can discount a bad connection at the bulb. If the front and rear turn signals work on that side, then you can discount the flasher being the problem. If they don't, it's possible that one side of the flasher has gone bad. The flasher is located to the left of the steering column support bracket, kept in place by a spring metal clip.

I GOT ALL THE SUPPLIES TO CLEAN THE POS EVEN BOUGHT ALL ...ALLL NEW BULBS JUST IN CASE A BAD ONE TRIES TO SNEAK THRU.. ITS EASY TO RUN SHORT ON PATIENCE WITH WIRING ISSUES,, THEY HAVE TO BE THE WORST PROBLEM TO HAVE WITH ANY VEHICLE ,,AND I HAVE WORKED ON A HECKOVA LOTTA CARS.....FRUSTRAITING.......................

I would rather pound my balls flat with a sledge hammer than hunt down an electrical problem.

that said, start with a trouble light and check to make sure you have juice, no juice follow the wires back to their ground, there is a separate ground for the side marker light and the parking light, make sure they are both clean and tight. both are under the hood but not connected together. then try putting your point of the trouble light on each of the contacts and ground the alligator clip . that will tell you if it is a bad ground or no power.

from there trace your wires back to find out if you have a damaged wire.

Before you work on the car again, I highly suggest you calm down. It's never a good idea to work on a car mad and frustrated.

S***canned an employee for getting frustrated,
Hummed a wrench, bounced and cracked a window.

Take a night to relax.
I've left my car in pieces and called it a night over valve
Adjustment issues.

GOOD ADVICE NITE ALLLLL

I'm having similar problems right now.... The ogre's cave is the place to be. Start with the ground connections in the headlight well. I think thats where my problem is anyways. I've got no park and an interior indicator illuminated all the time on that side......

Being old cars I have found a few broken wires on the fieros I have owned that caused turn signal problems.
