heater fan problem

I would like anyones help in finding a solution to my problem. I have a 96 pylmouth minivan and the heater fan has quite on me. Up north in canada it gets pretty cold, and the 12V plug in just doesn't do the job. I have replaced the fan motor, it was burnt. I also have search in vane for this blower fan relay they say is in the system, with no luck. I have no power going to the fan motor as it is shown in the wiring diagram. The resistor is ok, fan motor is new, and heater controler has check out good to. So I am back to finding this relay location. Any advice or info would be greatly appreciated as I have three young boys that are freezing, and my wife is not happy either. This is my only source of transportation and is driven to work everyday over 120Km one way. I thank every one in advance for their time and advice.

I had a similar problem a few years back. Though I don't no where the relay is off hand. The problem I had after replacing the fan motor was a poor ground.
