relay in dash clicking/switching for no reason
 

Okay, when I'm in 3rd or 4th and leave it in gear and let off the throttle completely, to take a turn or slow down a relay in my dash clicks. Sometimes it clicks once other times it does 5 or 10 times really fast. Any idea's. I do have power surges in my gauge cluster. It goes dim for no reason bu that was way before I ever heard the relay swithing... anyone else experience this???:(
