My blinkers were working now they are not. I cant seem to find a wiring diagram or info on if there are any relays in the fuse panel or under the hood. My hazard lights still work. I dont know about the relays, it may also be a ground from heavy rain we had or possibly the switch is gone. Can you tell me how to find a diagram or also if there are relays. My vehicle is a 93 jeep grand cherokee, 4.0 L -v-6. Thank you for your time.

Would need to test power from the headlamp switch . Go to http://www.bbbind.com/free_tsb.html free wiring diagrams. Enter your vehicle info , year ,make , model an engine . Under system click on lighting ,then under subsystem click on external lights .Then trace out where the tail lamps get power , do you know about automotive electrical circuits ,how to read a wiring diagram . Go on youtube check out videos on basic automotive electrical trouble shooting , how to do voltage drop testing an how to read wiring diagrams . Then get yourself a DVOM - digital volt ohm meter . Then test the circuit ! That's how automotive electrical problems are found .
The signal wire going to the right front has a splice for the dash indicator, a wire branching off from the turn wire and going to the dash. It sounds like that right signal wire is broken or lost a connection before it splices off to the dash, so the problem sounds like it is under the dash, either coming out of the turn signal switch to the flasher or from the flasher to that splice. You may need a multi-meter to check voltages on that wire at various places under the dash. Ascertain which color wire you need to concentrate on. Check for voltage on it with key on and right blinker on-voltmeter will spike to battery voltage, then fall to zero as the flasher breaks voltage continuously, if checked after the flasher. If checked when leaving the turn switch, it should be a continuous signal on that wire. Think you better find a wiring diagram to find the right wire to check. Good luck.
its actually located in the TIPM. more like a internal circuit breaker to protect the system. will have to have the TIPM reconfigured to vehicle spec with the dealer scan tool. problem is it doesnt always work because it shorts it out and/or you can only do it a couple of times berfore it has to be replaced
See if you can locate a wiring diagram for your vehicle. I have a 92 Seville and the wiring for the brakes and blinkers runs through the turn signal switch. The switch generally goes bad just from everyday use. They lose connection and you get intermittent problems (much like yours). Consult a wiring diagram, if they do run through the switch then I would recommend replacing that. Start there. Cheers.
