Stereo & Electronics - Left Turn Signal Intermid works..

I have a 1998 Camaro Z28. Sometimes when I put on my Left turn Signal it doesnt blink and Sometimes it does. This only happens when using left turn signal. The right works 100%. When it doesnt blink for left turn, some times the left arrow on the dash doesnt light up and sometimes it light extrremly dim, but doesnt blink and sometimes it works fine and blinks. i replaced the bulbs front and rear, new flasher, and just replaced the whole turn signal switch. same thing happens. The left front parking light did have some water in it and the sock did have some corrosion, but i cleaned it. Any suggestions or help would be greatly appriciated. Thanks

corroded wiring somewhere?.... sounds like a bad connection somewhere to me...

do you think the socket that I clean ed on the left side could be bad? Maybe i'll try to reclean it again

try a new flasher ($8 bucks), but whatever you do, don't believe the Haynes manuals, the turn signal flasher is to the right of the column, not left like it states in their manual. I learned that the hard way.
