what can i check, or how do you guys recomend that i go about finding the source of the problem.

Thanks in advance for the help.

Either the fan motor is dead, or the resistor pack, or both.  They're fairly easy to get to.  Let me look for a good write-up.  If the fan works on high (4) only, the resistor is shot.  Otherwise, the entire blower motor might be bad.

It's even on an M42!  This is just the board...the blower fans & motor comes out with a little steel clip in the center that holds it in.
