    Anyone who can help me out on this would be greatly appreciated. So I have a 2001 Ford escort zx2 that I recently acquired and came to find an electric issue which is as follows. The passenger side blinkers blink fast but only with the headlights on and the blinker indicator on the dash is slightly aluminated when the headlights are on. I have done a little research and my best guess is that it is a faulty ground however I have no idea where this system is grounded or wiat wires to check any assistance would be greatly appreciated I have built cars and motorcycles for years so feel free to explain in technical terms I'm self taught though and electrical isn't my forte hence my pleading for help on the forum.

    I second this. Most of the time if a blinker is blinking fast its due to a brunt out light.

    While I do appreciate the reply all of the bulbs are properly functioning that's the first thing I checked as I know what typically causes the fast blinking. I also checked all fuses relating to the system and headlights all of which are in good order. I even remembered to change the blinker oil ( joking ). As said before all bulbs are functioning fine until I turn the headlights on then all bulbs are still on but blinking fast.

    Update I'm an idiot and didn't really look at each individual bulb until just now and 1 of the rear passenger bulbs is out while I do feel like an idiot I'm atleast glad it wasnt anything worse thanks for the help it's greatly appreciated I'd rather find it to be an easy cheap fix then something worse.

    Update to my update after further investigation the bulb wasn't blown it was the socket that's malfunctioning. It won't make contact with the bulb if it is fully seated yet of I pull it put slightly it works just fine. I guess as long as it works in the end that's what matters but technically wasn't just a blown bulb.

    Besides the Ford Service Manual for your car, which doesnt have many wiring diagrams, there is a companion manual, called the Electrical and Vacuum Troubleshooting Manual (EVTM) which has all the wiring diagrams, including pictorials of the locations of components - including all of the grounds. It is sort of complicated. Each of the grounds is important for some purpose, and each of them can get rusty.
    The bulb sockets will also get corroded, and you have to wiggle and scrape to try and get a new bulb to stay lit. With one of mine (I have five 2nd gen Escorts) I have to solder the base of the new bulb to a separate ground wire.
    I got all of my EVTMs, (they differ from year to year, so one for each different year of car) from ebay, and each of them has been valuable for finding problems.

    If I had my choice between a bad socket and a bad ground (which was probably the next thing to check), I'll take the bad socket!!
