Blower motor switch inop
The blower motor switch won't change the speed, only works on low in my 79. Is this the switch or the motor?

Low doesn't run through the blower switch,sorta goes around it.
Check the yellow wire at the switch for power,
no power on yellow= a prob with the controller head
power on yellow= could be a bad blower switch but you need to check the tan and blue at this point
no power on tan and blue=bad switch
power on tan and blue=bad resistor board
