I have a 2004 pacifica. About 6 months ago I was cleaning the headlights with a drill buffer. Since then both my turn signal and running light on front drives side do not work. The indicator flashes rapid and the rear blinker still works. Ive replaced bulbs and also headlight sockets and wires just for the headlight. Ive used a wire light tester on the wires and sockets and there is power. The second i insert the bulbs they stop. It snowed for the first time last night and both lights started working. Got warmer out this morning and snows melting and they both stopped. Assuming its a short but im out of ideas on what would addect both the running light and blinker. I need HELP!!

 

Welcome to the forum. You might get more responses by posting your question in the Pacifica part of the forum rather than here which is intended to be the place where new members introduce themselves.

Anyway, since you have satisfied yourself that you have power to the sockets, it's time to look at the other side of the circuit and check the grounds. Since the lights seem to work in wet conditions I would suspect a faulty ground. Follow the ground (usually black) wires from the sockets to where they are grounded to the body. There's usually a screw attaching the wire to the metal. Loosen the screw a little, wiggle the wire to break up any corrosion and re-tighten the screw. See it that helps.

 

Checked and cleaned all 3 grounds under the battery tay with no change not sure if the are any other. None found in my research and visual check... Any other ideas?

 

If I recall correctly, Pacificas have a real problem with wiring under the battery tray. Search in the Pacifica forum for what people did to rectify the problem. There's at least one big thread there discussing the issue.
