Blower motor not coming on at all. Ran test light. I have power at red wire with light grounded at (-) battery. I have power at black wire with light grounded at (+) battery. No power at gray wire with light grounded at (-) battery. I ran these test with car running hvac set at 75 degrees and had someone adjust fan speed as I was testing. Then ran test with vehicle off and got the same results. Previous owner replaced blower motor. Ive checked all fuses and I know theres not relay for the blower just and air conditioning and heating programmer. Should I replace blower motor again? Or should I replace programmer or dash panel switch?

Replace HVAC controller it is standard to replce it when blower is replaced. Blower AMP draw goes up and damages controller. Blower speed controled via Gray wire from controler
