More than likely this is a blower motor issue, so I am attaching the info that you will need to help figure this out.

Here is a guide that will help with this type of info:

I suspect you will have to replace the blower if you have power back at the connector. So I am attaching the info to be able to test for voltage at the blower.

If you have voltage, then I attached the instruction on how to replace the motor.

Please run through this and let us know what you find with this.

Thanks
