Might be the resistor on the a/c box..It controls the speed of the blower motor.

Yes I have that book and The blower works on medium not low or high or Hi I was thinking It has to do with the connections up in the - on the speed control

I found out what the problem was With the blower motor on my heater. A few different things went through my mind . As I was putting the heater Box in I kept checking The blower motor , it worked the whole time until I had it Bolted up . The 3 bolts that Holds it up against the firewall where too tight is stopped the blower from rotating . I thought that it would be something else to check if somebody else had the same problem problem I learned something new every day .
