Do they ground at G100? On my truck, EVERY connection that went there was rusted out, and broken. (thus, no start, as the fuel pump grounds there as well....) In front of the battery WAY down on the bottom part of the fender. It's a stud that sticks straight up. a BUNCH of wires go to it, and most are soldered to a single connector.

 

yes I checked G100 by using a test light and I have ground. I’m so confused why I don’t have lights.

 

One of the challenges trying to help over the Internet is that we can't see how you are doing tests so apologies if this is a redundant question: Did you test the ground at the lightbulb sockets or down at the G100 ground point ? There are what Chrysler calls "joint connectors" between the lights and the ground point.

 

yeah so I checked ground first at the G100 ground, had ground there, moved to the socket, tested for power on one side. Had power and flashing when turn signals on. Other side of the socket had ground on both ends.

 

Now I'm baffled too . Do you have the correct 3157NA incandescent light bulbs ? Running out of ideas....

 

Is the bulb in the socket the correct way? The bulb only fits properly one way, but it will actually go in the socket in two ways...

 

yep 3157Na bulbs

 

It occurred to me that if there is a phantom ground that makes the tun signal work it would also fool your test light. Try rigging up a temporary ground at the three pin connector, black wire to ground.

 

not sure what the three pin connector is but I’ve got three wires going to that socket. A wire for park lights, a wire to the turns and a ground wire. Is it possible to ground the black (ground) wire to try?

 

Yes that's the one. Chrysler calls it a "connector" I guess because it connects to the bulb. Note there are only three wires although the bulb has 4 pins, the two grounds are tied together in the "connector".
