then I would check the blower motor contactor. Find the control box and look for a brownish to burgundy colored relay. Could be marked in white ink, Arrow-Hart or Allis Chalmers on the cover. Usually rated 30 amps open style with a 24 volt operating coil. The compressor contactor looks the same only slightly bigger "physical" size but still operates off 24 volt. I'd have to see the control diagram to see how the blower is connected in the circuit to troubleshoot it further as there are high pressure and lower pressure limits in the system.
