ok, i have an 87 GT and heres my problem... my signals dont work, ive checked the following...fuse, flasher (changed both of them), connections to switch all seems fine (also the owner befroe me installed a new multimalfunction switch not too long ago)
i recently chenged my headlight switch and put in a repair harness, after instalation i checked and the signals worked, i went out to the car the other day and discovered the problem
the hazards also work (the dash and exterior lights work), as does everything else on the same fuse (backup lights, defroster etc) works
HELP ME IM STUMPED what else am i missing and could i check
PLEASE and suggestions at all

did you check and make sure that where they repair the harness didn't come loose?

check ignition switch

The airbag and non-airbag cars use different MF switches. Perhaps that's an issue.

Also, on the leading side of the circuits (for sure - it might be the entire circuit), the hazard and Turn signal circuits can really be thought of as independant.

If nothing changed parts-wise but now there is an issue, start checking in/out voltages as you chase the issue. It might just be a backed out wiring connector or bad connection.

Good luck.

How are the in and out voltage tests going?

That's the only way to track down an issue like this.

Good luck.
