You can really inspect the windings individually, they are built into the fan motor. Have you tried individually grounding the the center pins on the relay yet?

Yeah I looked into the high/low speed connections but there good, I think it's the ECT sensor and will probably just change thermostat at same time.

Yeah I'm ordering the ECT sensor today, from my inspections the ECT seems to be the issue, thanks for your help bro.
