Blower motor - I must be missing something

Here's the issue. For a fewe days, my blower only operated on 5 (high). 1-4 were all inoperative. Then 5 stopped and now, I'm deadd in the water. I've purchased and installed a blower motor resistor, but nothing. I pulled my volt meter out and checked the voltage at the blower motor control module. With the key on I got anywhere from 14-17 volts across terminals G&E. I was expecting more like 13v, but either way, it's good to see voltage. I got 0.15V across C-E (Med 3 to ground) and 0.15V across D-E (Med 2 to ground). The best I can tell is that I have a Blower Motor Relay issue. Problem is that I can't find this little bugger. The schedmatic lists it. I checked for voltage at the Blower Motor control Module harness and had 0V across B and a ground.

ANY thoughts????????????? It's driving time, but way to chilly for no heat!

Whether there is a blower motor relay, depends if you have manual or dual a/c. Dual does not have a separate relay.
