I was driving my '91 LX the other night and noticed my headlight switch was not staying in place, like it popped out from going over rough road with bumps, etc. Something to that nature. I tried pushing it back in, but only the left side (where the levers are) stayed snapped in. The right side wouldn't. My question to you all: Is there any way I can fix this without having to pay $90 for a new switch? Is this common among '79-'93 5.0 mustangs? Thanks in advance!
