Checked voltage at motor connector. 8.3 v . Purchased new blower motor ,pulged in connector ,still not working. Please help

Any voltage when connector is plugged in? Does it change with speed selector? Should range from about 3, 6, 9, 12 volts as you go up in speed. How about your ground wire connection at the body? I highly suspect the resistor/relay module in the the HVAC case next to blower motor- look at connector contacts for burnt, melted spots- to find it- follow purple wire from blower motor back to resistor module.

Thanks,
Replaced resistor module, blower motor working good .
