How do you check the fan resister to see if it's good on 2000 Jeep Wrangler

My HVAC fan worked intermittently for a short time and then quit all together. Fan resister? or Fan switch? The fuse is OKay

the fan resistor is either good or bad.
the switch may be the issue but you would need a voltmeter to confirm power.
the most likely issue is the blower motor. common failure.

Thank you for responding Roy. I appretiate your time. It started working again, a few days ago and I've had no problems since. I am affraid it's going to turn out to be a loose ground or a short to ground somewhere. Either way it's not going to fun finding it.
