Back to my new beater (beaten?) Ranger. I have no turn signals... the left front blinks in rapid fire, as if the rear bulb was burned out; the right side doesn't seem to work at all, but did when I test drove, went out a mile down the road after I'd paid for the truck. Using my multimeter, there is no power at the left rear nor either of the right side sockets, The schematics I have don't match anything in the truck, and don't show relays, which wouldn't seem to work on the left side, anyway. If anyone has legit suggestions, I would greatly appreciate them. Thanks, Glitch.
Update: emergency flashers do not work except for front left. Tail, brake and marker lights work. Glitch.

 

here is the wiring diagram I have for 1998 Ranger exterior lights

Check for trailer light wiring, some DYI wiring can cause issues

1998 just has the one flasher for turn and hazard, not separate flashers

 

Thank you.
