My 80 SC has a weird issue with fast turn signal blinkers, both left and right. I've read this could be caused by a bad or loose bulb, or dirty contact, etc. I've checked my bulbs and cleaned out any dirt and contamination. They all looked pretty clean, but I sprayed electrical contact cleaner inside the housing, etc., just to be sure.

The strange thing about this issue is that it always seems to 'resolve' itself after a few minutes of driving. It's like the issue is eliminated once the car is warmed up. Its very consistent, never have a fast blink after a few minutes of driving.

Does anyone have any suggestions as to what could cause a 'time sensitive' fast blink on the turn signals?

Thank
