In past posts I have written about getting no air from my vents. Replaced the blower motor and blower motor relay, nothing. Relay was tested and was no good. Jumped the relay and air came out of the vents. Put new relay in, nothing.

On rccm, slot 19, green and black wire, seems to control this blower motor and its function (shorting it out, fans came on). Do I need to send the rccm back again for repairs or is there something else that's missing? (BTW, my son came into town and did the diagnostic work for me)
