Hopefully this will help Tim and maybe some others. It is based, partly on info I found somewhere else, but I can't find where now.
This is a 2004 Town & Country with manual climate control.
What I did.
Blower quit working. So. I thought, fused. I checked the fuse compartment under the hood. There is a 40A fused for the front blowers and a relay. The fuse checked out and the relays checked out.
So I thought. Switch. I pulled the center console panel off and checked the wires with a volt meter to try and find the hot wires (thinking I could short the wire to prove that it was the switch). I couldn't get a voltage on the wires. So I followed the wires around the console until they came out right behind the glove box.
The 6 wire harness plugged into a box just behind the glove box. Right next to the harness is a 2 wire harness. In my case, the wires were green and black. This is the blower motor wires. The box that both harnesses plug into is the blower resistor. It is held on by two screws. Per advise, I tested both motor wires against ground with a voltmeter. Both read 12 volts. If they hadn't, the problem was supposed to be the motor. I wanted to be sure it wasn't the motor, so I tested it by jumping the black wire to a ground. As expected, the fan kicked in on full speed and blew cold air.
So. I haven't convinced myself that the switch isn't bad. BUT, everyone says that the resistor is the most likely cause. I checked around and found a resistor for about $20. I figure $20 and a 2 minute replace process it worth it even if it turns out to be the switch.
Thanks for your help.
