Hello,

It sounds like a wiring issue. You should have 12V at the blower connector.
You could have melted wires in the blower harness. This could also be due to burnt pin at the blower connector.

To figure out the wiring issue will require to trace the blower motor wires and find the possible cause.

Here is a helpful guide on how to check wiring harness:

I have attached the wiring schematics for the blower motor below.

Please let me know of any questions.
Thank you.
