Turn signals stopped working after clutch cable replacement

Post by jfarr » Sun Aug 12, 2018 8:57 am

Had the clutch cable replaced in the car by my local garage (I was too big a wimp to attempt it). Ever since I got the car back, the turn signals don't work. Everything else is fine in the car including the hazards so I don't think it's a fuse if my manual is to be believed. What should I check first?

I would have to pull out my wiring diagrams to say for sure, but the first (easy) thing I would check would be to see if the ground strap (in the transmission tunnel to the tranny) is secured.

I'm thinking most cars Hazards work with the ignition key in the off position. So that circuit would be protected by a fused "hot all the time circuit" The signal lights only operate with the ignition switch in the "start or run" positions. This would be a different fused circuit from the hazards. Have you checked the signal light fuse?

Are there 3 wires on the signal flasher?

Manual states that fuse “I” runs the turn signals and a bunch of other things that are still working so fuse is fine. I checked them just to be sure.

Wiring diagram shows three wires to the flasher unit but I don’t know where it is physically located to check.

All wires in the vicinity of the fuse panel and the underside of the driver’s side of the dash are connected and seem okay.

Check the ground in the trunk. Yes, I know they weren't supposed to be in the trunk.

Simple stuff: Check they didn't dislodge the flasher relay, or break the wire running from the switch unit to the fuse box, etc.

If this car is a 1974 there is a hazard flasher and a turn signal flasher. I think the turn signal flasher is located above the ignition switch behind the dash. Its attached to the peddle assembly an the side facing the center consul. the wire colors on it are gray which is power from the hazard switch when the ignition switch is on and the hazards are off. Violet which goes to the steering column switch for selecting turn direction and Light blue which lights the turn indicator green arrow in the speedometer.

As Brad said, stay simple. My guess is the flasher unit on the steering pedal frame came out of the clip. As I recall, in needs to be in the clip for a ground connection. 30 seconds under the dash with a flash light should show you the problem.

Thanks, I'll check for that when I get home this evening.

Well folks, it turned out to be a simple case of a worn out flasher unit. Replaced it and all is well now. Just seemed damned odd that it would occur precisely as the clutch cable was replaced.

I would suggest it is indicative of a bad ground.
