Blower motor switch question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My blower motor hasnt worked on my truck for years now and today I decided to give it a look over. I put a checked the hot wire that goes to the plug that goes onto the back of the switch and it barely has any juice going though it (the tester had a very faint red light). I traced the wire all the way to the fuse box and I looks impossible to find not only the wire in the box but the problem (electrical is not my strong point). Would it be possible to splice that wire in with one of the many wires in the bundle that gets power when the key is on?

check the ground on the blower motor first. run a wire from the ground of ur battery to the blower ground, see if that helps. most electrical probs are the ground. my .02 worth.
