due to a short in wiring is it likely that an integrated relay module has been damaged and stopped the blower motor

The blower motor uses a resistor to control the speeds. It is possible it is burned out.

I saw a small resistor on firewall area but did not know about it.Can you send me a wiring diagram of the blower motor circuit please? I could probably take it from there
