4 - way flasher issues

[soupman]

My four way flashers aren't working. All of the bulbs are good and the turn signals and brake lights all work fine. I can see the turn flasher in the fuse block. Is there another flasher for the four way?

Also, have misplaced my factory manual... can anyone point me to online wiring diagrams

There should be another flasher relay. Look in the upper left corner of your fuse block.

thanks TJ66. I've searched the forums and found a diagram for a 1980. close?
The upper left area had a wire coming out. I may have to run down some "custom" work the PO did...

thx

Isn't the 4 way flasher above the gas pedal on the "convenience center"?

In any case, can always swap with the working turn signal flasher as a quick verification. Those flashers are pretty fail proof.

Some progress... I found the 4 way flasher location on top of the steering column. Not what I would call an ideal spot. I replaced the existing flasher with a new one from Advance Auto Parts. Still no joy, but... now at least the two indicators in the dash light up. All the bulbs are known good, and all of the parking and blinker functionality has been confirmed. I think there may be LED's in the rear side markers and maybe the rear - would that affect 4-way flashers?

Posted response in other. My experience is they may light up, but LED's are also likely to require an electronic flasher. Probably dirt cheap off ebay. All coming from China anyway, might as well cut out the 3 or 4 people making money between China and you.
