Side Marker Light

[jlampka]

I have a 1971 Chevy pickup C20. All of my exterior lights illuminate except my passenger front side marker. It flashes when I turn on the directional but doesn't illuminates otherwise. Any one have this problem? Thanks for any help in troubleshooting.

Oh I swapped bulbs and the same condition still exists.

I had the same problem.myturn lamp would work but no park lamp. The indicator on the dash would stay lit. It turned out to be a bad connection at the bulb. I cleaned the socket with sand paper and greased the light socket with dielectric grease and it works good.
