I have replaced all fuses and resistor pack along with replacing climate control . I am not getting any power to the resistor pack plug is there a breaker between the climate control and the resistor pack that could have gone bad? I am at a loss and can't figure what else to do.

Good morning,

I attached a wiring diagram for you of the blower system. The red wire comes from the fuse block for the resistor. I circled the fuse for you to test for power.

Let me know the results.
