Yep the simplest of things, a car I just got signals didn’t work.. I didn’t realize it had a separate relay .. Thank you. Fixed

Thank you. I’m restoring a 72 chevelle. No turn signals at all replaced the cancel cam and switch as the owner before me put a aftermarket steering wheel in. I assumed that was the issue to no avail. Also replaced all of the exterior lighting fuses and the flasher relay on the fuse panel. I did some reading on a forum and found that just like the mustang you’re working on, I also have another flasher relay (just for the turn signals). I did the jumper wire trick, and the signals came on. Hopefully that relay is the only issue and I don’t have more of a wiring problem down the line.

I have a 1979 trans am and the all turn signals are inoperative. I can’t figure it out, but here is what I’ve put together so far:
- Hazard flashers, Headlights, taillights, dash gauges, and parking lights appear to function normally (all bulbs are correct)
- 11.6V to turn signal flasher (pink striped black wire) when key in “on” position, 0V when key off (believe that’s normal).
- Bench tested flasher and it functions (it’s also new)
- removed and jumped flasher to remove that variable and voltage is still there until turn signal is up or down where voltage goes to near 0 at that junction (this has me confused…where’s it going?).
- continuity checks are confusing: From flasher output (purple wire) to front driver bulb (either contact) is open with signal lever off and 0 ohms with lever down. Grounding tab at that bulb is a good ground. Both contacts are grounded with lever down (this is confusing to me, is that normal?).
- with brakes pressed and brake lights on, lever down turns off left rear brake light and lever up turns off right rear brake light (believe interrupting the brake light is normal, except the light is then supposed to flash).
- the battery is grounded to the engine block and core support. Engine block is grounded to the sub frame and the firewall.
- the front light harness is grounded to the core support on both sides. The rear light harness is grounded in the trunk and under near the fuel fill neck.

I think I’ve ruled out a bad flasher, some grounds, and bad or wrong bulbs. Anything else?
Does that leave a bad ground somewhere other than what I said above and the turn signal switch?

I have a 2002 Cadillac Eldorado and my turn signals don't want to work in the cold, And they make a weird noise. Once The car gets warmed up they start working again. Usually at some point down the road. And I need to use them three times before I get on the main road to go straight into the town. I don't know everything about this car yet because I only just bought it in July from the car dealership in my area. Once the car is warmed up they work fine.

I have a 1992 foxbody and I was hoping I could get some advice here, I’ve been restoring/fixing it and ran into a problem with the turn signals. Originally the turn signals wouldn’t work however the hazard light were working fine. I did some sketchy work in the hazard switch that seemed to work. Later during the safety I found out the left turn signal doesn’t work when the running lights are on, however the right turn signal works fine with running lights. Advice?

Replaced the switch in my 1970 duster, now the car cranks but wont start and the horn honks non stop

Question: I have a 1970 Ford Torino. My turn signals work fine during the day, but at night when the headlights are on, the turn signals don't work. They light up, but don't blink. What would make them blink only when the headlights/taillights are on?

[MUSTANGMAN]

What if all your turn signals work except for the ones on the brake lights? 1970 mustang

[SS_B]

It doesn’t work when headlights are on or when brake is applied
