How can a main relay cause fan speed not to work? The main relay is for running your fuel pump and injectors!

Oh and check your fan blower relay. :)

The resistor block located in the front of the blower motor has burnt out the second resistor.

yes
this is it
resistors are blown on the resister block
use a multimeter to check the resistance according to the service manual

its not the relay
if relay is blown the fan wont work altogether.
