Just did a search on alldatapro. Com, not seeing a blower motor relay. Only a resistor, or a switch. Does the blower motor only work on high? If so then you need the resistor.

THE BLOWER MOTOR DOES NOT WORK AT ALL SO PERHAPS I WAS WRONG ON THE NAME OF THE PART. LETS GO WITH THE LOCATION OF THE RESISTER, OR SWITCH AS I THINK THAT'S PROBABLY MY PROBLEM. THANKS AGAIN FOR YOUR HELP. DEACO

If its not blowing at all, sounds like the blower motor died. Usually if the resistor is bad, they only work on high. Check both.
