78 C10 A/C question

How do I tell if the fan switch is working without taking the dash apart?
My A/C wont fire up, fuse is good and power to the red, hot side of the fan reley. I jumpered across the low pressure switch at the accumelator still wont fire . when I jumper across the reley red to the yellow everything starts and cools but the reley gets very hot! What next?
