yup could be the main relay, mine did the clicking and even died on me once while driving too. Got a relay from advance for $40 bucks, changed it, It was all good, didnt have that problem again...and make sure you have good ground from the engine to the chassis too

My friend had the same problem. turned out to be a grounding issue with the Ground Terminal on the battery. check that and all other grounds. good luck!

BINGO! Check your thermostat grounds, engine/batt ground wires, and if all else fails splice a new ground in for the main relay.

check grounds. take the relay apart and look for cracks in the solder joints. if cracked solder them back together.

Your problem is, As stated above...a bad ground. You say you "checked" this. How? Wiggle some wires...? get a multimeter and fix the ground.

check the ground with a multimeter from the the relay to the negative battery post (u might need a long lead) and it should not have more than .03 v of resistance.... if u think its a ground problem... when a relay click it is being energized so thats what the clicking is... u can also use a jumper to check if its the relay
