Hi,

I attached the entire wiring schematic below for the HVAC system. There isn't a relay for the blower motor. Are you referring to the blower motor resistor? Take a look through the schematic and see if it helps.

I had to cut the pic in half to make it readable. But I did overlap them so you could better follow.

_________________________________

If it is the resistor, it is mounted to the bottom of the heater-A/C housing, under the instrument panel, and just inboard of the blower motor.

Let me know if that is what you are looking for.

Take care and God Bless,

Joe

If you get this same issue, he is correct, there is no blower relay. I found my fault in the white plug right by the blower. Look very closely at the green wire that changes to red on the other side. I'm guessing the connection there was not big enough for the load over the long term. I soldered the wires directly on mine. On such an old vehicle I don't see the need to try to replace the connector itself.
