69 gmc c1500
 

Needing help, I replaced my turn signal switch and I have a grant steering wheel on the truck that has missing parts for the horn. The truck is a 1969 GMC C1500. The steering column is keyless no tilt Automatic on column.
So the problem I am having is when I turn on my blinker (either side) it takes them about 10 to 20 seconds to start blinking and then they start blinking slowly at first. Any ideas that would cause this?

Change out the flasher.
It’s usually on the fuse box or close to it.

x2. If not that, probably need to ground better. Probably a tired flasher though. Just pop it out and pop new one in
