Electrical problems

Ok so when ever i turn my A/C on all the way the ABS light comes on. Even when i turn the ac on to its max it does not blow as hard as it should. Sometimes when i hit a bump the a/c starts to blow as it should. Also the passenger window stuggles to go up and everytime i roll it up the A/C lights begin to dim and the whole truck shakes, the subwoofers also rumble when doing so. Keep in mind when i hit a bump everything fixes itself. It may be a bad ground wire but i just dont which it could be.

Abs issue- prob need a module rebuilt
HVAC issue- prob need a resistor
Passenger window- definitely need a window regulator

check the ground that comes from the engine block to the cab, usually a flat braided  wire
