Turn signal Puzzle

950 Views 7 Replies 4 Participants Last post by  patrykrebisz
Hi, I have a '78 450 SLC. The turn signals flash very quickly when engine is cold. Normally, quick flashing means a blown bulb, in this case, all bulbs are good, after the car warms up, the indicators slow to normal speed. Any ideas ?

This can be a symptom of a failing flasher relay. When the relay warms up from use or ambient temperature it works happiest.
