You may use a Spike for the window motor.

if(p2_sw_aux1 == 1)
     {
     pwm05 = 255
     }
else
     {
     pwm05 = 127
     }

This code looks valid, except you are missing semicolons at the end of the "pwm05 = XXX" statements. Also, I'm not sure if this applies to the new controller, but the old controller didn't like PWMs being set to 255 -- we were told to use 254 instead.

I'd be willing to bet this was probably caused by some code error that you accidentally remedied when you changed to the Spike. If you posted the exact old and new code, we might be able to better help you.
