2015 a/c problems

Hello everyone I’m new here, my 2015 tacoma pre runner all of a sudden won’t blow on high very hard replace the motor nothing change it’s cold but the blower seems to be like on low….anyone with the same problem I appreciate all the help

 

Never had it in one of my Toyotas, but when a dodge I had did that it was a resistor.

 

In my experience, a blown resistor will allow the motor to run on high but not any other speed.

 

Backprobe the blower connector with the blower plugged in, with it on high the voltage there should be within 1v of battery voltage.
