once you've got the cover off you will see 3 screws holding the controllers in place, unscrew all these and you should be able to pull the unit out and access the switch
the other problems these had was the blower dial itself packing up
and then there's the wiggle test on the wires for the blower motor
My shonkys 93 and you are correct kills the blower
