Wrencher, thanks again.
I was just checking the flasher and decided to change it again with another from the other car. They did not blink then decided to push the emergency flasher in and they worked...all four lights but when I tried the turn signals, it just light up but didn't flash.
I took each bulb out and all appears to be okay. This Chevelle only has one flasher.
Is there a ohm test I can do?
