Not getting any power to the ac system or cooling motor, all new ac parts have been installed.

Hi jtspennington,
Thank you for the donation.
I need some additional information to understand the problem better.
Is the blower motor working when turned on?
Are the control panel components functioning correctly?
Is it only the A/C compressor and cooling fans that are not working when A/C is turned on?

The cooling fans for A/C operations would only come on if the compressor clutch relay is engaged.
At the compressor clutch relay (behind left side of front bumper), test for battery voltage at the Black/Yellow wire with ignition switch ON. If voltage is available, use a test lamp to ground the Red/Blue wire and note if the compressor clicks and cooling fans turns on.
