Turn signal problem

Hi All, 72' Dart, things that work..4 ways, brake lights, head lights and left turn signal flashes. Right turn signal does not flash but the lights just come on steady. I changed the flasher once already, same result. I have a spare used harness and switch that I hooked up, no change. Any thoughts on where I could check next? Alternator puts out 14.3 and battery reads 12.6 with the car off.

Check the grounds at the bulbs and sockets.

this tells you that from the connector behind the drivers kick panel that it is good downstream from there & also downstream forward past the firewall to the front lights including grounds cuz 4 ways & brake lights use the same large filament(s) in the 1157 bulbs. The TS flasher works both sides so it is OK. seperate the dangling ts/brake harness under the st column & ohm the col half for a start. try the stalk up/down & check continuities. this'll tell us if that assy is the problem.

Thanks, I'll check some of this on the weekend and let you know.

I stand corrected: ground the metal case of the (2) front/rear pass side 1157 bulbs & see if this straightens things out. I think Stump nailed it.

Check the bulbs.Do all the park lights come on? Its possible to get a bulb in backwards and it wont flash.Rocky

i agree with rocky. if the bulb is installed wrong, sometimes it won't work correctly. i have delt with this many times over the years.

agreed, I would see if the running lights (small filaments) come on on all 4 corners then see if the large filaments come on on the pass side with the stalk raised up. wouldn't hurt to have a helper work the stalk while you outside see if any of the filaments get dimmer when the TS are activated on that side.

Thanks, you guys nailed it, got everything working again. Checked all the bulbs, most seemed ok, replaced the two 1157's in the rear outers. The left one was a little punky to come out ad took me a few tries to seat the new one. The socket was a bit gacked,it looks like a bulb has been pushed in there incorrectly a few times. The only remaining symptom is everything on the right is a tad brighter than the left, flasher is a bit faster too.
