Try cleaning out the contacts with some emry paper and re-bending the tabs a little.

im glad i found this thread. my driver side headlight isnt working. i think im gonna go to pick and pull today and hopefully get a switch. glad to know the g20 and b13 switches are interchangable. =]

I know this is an older thread, but I'm in the process of changing the headlight switch. I was at the local pick a part and they had a G20 with airbags. My 91 G20 does not have airbags. Does it matter?

airbag doesnt matter. pull the plug on your car and count the pins/shape of the plug vs. the junk yard part.
