Flashers work but not left turn signal nor left indicator light
This seems to me like it must be a bad connection or ground - but I'm hoping someone would have an idea where to begin as the symptoms seem a little weird.
I have a '95 Ford B Series. All lights flash when the flashers are on so I assume the lightbulbs and connections are good - but the left turn signal indicator doesn't work. The right turn signal works but not the left - so I assume it's not the flasher itself.
Those *were* the symptoms but suddenly as I was testing it, the left turn signal and indicator started working. So the indicator light bulb itself isn't bad.
It was hard for me to isolate the problem in the first place and then it went and fixed itself. I'm sure it will fail again as I'm cruising down the highway and I want to fix it once and for all.
I know I'm probably going to have to just get my hands dirty on this one - but any suggestions would be welcome!
Thanks - Jon
