Signal issues

I cannot imagine what in the cluster would cause this. It's not a "loop." It's a "branch. All lights are--or should be--grounded to return to battery negative. THAT could be an issue.

The TS switch has several "in's and out's"

IN is full time hazard flasher, that is full time battery feeds the hazard flasher (fused) and that power feeds into the TS switch

IN is switched brake lamp power from the brake light switch, also comes from a full time battery source

IN is turn flasher power which comes through the ignition switch--fused--through the flasher --and into the switch

OUT is left front, and branches off to feed the left cluster indicator
OUT is right front and branches off to feed the indicator

OUT is right rear which also is stop
OUT is left rear which also is stop

So go through it all one at a time. Test stop lamps and make sure they work properly. Test them with tail lamps on and off both, and look for abnormalties, which would indicate a ground problem

Then activate hazard. Locate the hazard flasher, make certain it is getting battery power, that is, actually check the voltage, and make sure voltage is not low. Compare to battery reading. With flashers activated, turn on park lamps and recheck, look again for odd looking lamps, again looking for ground problems

If no joy, try swapping flashers between TS and hazard, or a new one.

Then pull all 4 bulbs, check them for problems such as internal shorts between filaments, make sure they are the correct bulbs, and that they are indexed properly in the sockets. Damaged socket insulators can turn in the sockets and screw up the way the bulbs contact

I would concentrate on hazard first, get them working and eliminate that as a problem

IF YOU HAVE not wiring diagram, you can download them at MyMopar. The latest free service manual there is 73, which is some different than 74, but TS wiring might be "close enough."
