Why is the front blower motor not getting any power

Front blower motor works, just not getting any power to it, have power to speed switch but I lose it when I turn the switch on, all other wires are ground, all wires at resistor are ground, no power. I replaced fan speed switch, it didn't fix the problem. I installed a simple toggle switch, ran hot wire from fuse box, through 30 amp fuse, switch, than to motor. I grounded the motor using the same factory wire harness. Blower motor works, and I can even change the speed using the fan speed switch. I only found two relays under hood for blower motors, 1 for the front and 1 for the rear, both are good, all fuses are good as well, maybe there's a relay, that's hidden? Please, any help is greatly appreciated, thanks.

You might want to start checking the front motor controller. I don't have the location for it-

Thanks for rasmataz, what exactly do you mean by the front motor controller? Are you talking about the blower motor resistor? If so, I was thinking that, but I'm not sure since I'm not getting any power to it and the blower isn't working in any speeds. All of the ones I dealt with, you would still have high speed, since the resistor is by-passed for high speed. I should have also noted that this is manual temp control, not automatic. And I also noticed the a/c button does not light up either. Thanks

Dear sweet leaf,

I m having the same problem with my 2004 Toyota Sienna. I have A/C in the rear of the car but not in the front of the car. How and what was your resolution towards fixing the problem with the A/C in your car?
Thank you
