arc relays

I have no 1problems hen it is on firm ride but??? any clues where to start? this is a 1990 sc please reply thanks

If you count the number of times it clicks, it will tell you which ARC is the problem. Count from the left front back and around. Pop off the offending sensor, WD-40 it and the pin, carefully turn the pin back and forth with a plier and reattach the sensor.

That usually corrects the problem. If not, it's time to snap on a new one.
