front parking light /blinker woes..
i have developed a little issue courtesy of the electrical gremlins....my front parking lights which have always worked fine, don't work fine any more.....drivers side: no blinker, parking light works ok; Passenger side: no parking light, blinker works ok....both of the side marker lights work fine...its not the bulbs , and not the connections inside.....where are these lights grounded? also my inside drivers side blinker indicator on the dash glows faintly... any thoughts? thks bob

just had a 77 caprice act like that i also replaced the bulb's sence i was therechecked and replaced bulbs with known good ones, no difference, even swapped them still no difference, cleaned connections in socket with sand paper, no difference, rear blinkers and front side markers all work ok so i don't see how it could be the flasher unit....any thoughts? i'm thinking i have a ground disconnected somewhere any body have any good locations to check....all other lights work fine....

Thanks for mentioning it though...I'll follow this one closely.

Bob do you have a schematic on the car? I have one but it's 12 miles away!
I don't recall if there is a common ground connector? There should be a ground wire to the left front of the radiator support about 3/4 way down from the top of the support. Ground terminal comes out of the light harness.

Fixed more than one of those in my interior redo, it seemed over the years a 71'has more than a few rub points to short out to ground. Hear is a pict of one of my gremlins, but all is well now and no squeaks.

Thks Gary that was the first place i went to and filed the area down to bare metal and reconnected it... no luck.. i have a schematic, it seems like what i really need is a wiring harness diagram, i wonder if they make one of those? ..spent some more time on it today and i was able to get the pass side parking light to work by carefully filing the contacts for a while.... all the grounds checked out ok in both of the light sockets.....so now its down to one issue the drivers side front blinker is not working although the side marker is working fine....
any thoughts?????? thks bob

Had same problem and cured today.
I had the same problem on my 79. It is a ground problem and bad connections. On the underside of the front lip between both head lights tucked behind the wires is the main ground for the front lights.(all). The other is at the lower dirvers side corner of the raditor support. (front side). I Unfastened the grounds and sanded the corrsion of them and the body. Then I cleaned with a points file all the connections for my marker lights and running lights. This fixed all problems and cured the problem of the dim turn signal on the dash.,

thks guys this is an old thread.....problem turned out to be the physical connector that is on the drivers side up by the radiator core support.
