Window was stuck open. Found power to the yellow wire in the harness going to switch check wires going to regulator by hooking up lawn mower battery and closing window. Replaced switch the other windows work as they did with old switch but still nothing for drivers. Is there another wire that feeds power to the switch just for drivers window?

This circuit is far more complicated than that. The motor requires both power and ground to operate and the switches reverse that polarity to reverse the motor. It also has to be controlled by two different switches.
I am giving you the wiring diagram but you may need a local tech to troubleshoot the circuit to find the problem.
