Signal Questions 64 GMC
 

This may be an easy question....

In my 64 GMC, I have the left turn signal on, step on the brake and the stop lights come on so the signal quits flashing.

Right signal works fine.

There is a hazard flasher on the dash and everything looks like it goes thru there.

Think its that?

They are $200.00 or so on ebay? Where can I get one that’s not crazy? Or is it something else?

Thanks

Jay
