Did you check the fluid level? Try unplugging the master cylinder fluid level switch to see if light goes away.

Did you check the A/C magnetic clutch relay and its fuses?
Did you test the freon pressure?

Fluid level is ok, I unpluged the level switch the light stayed on on the air conditional fuse and relay are ok, I ran a wire to the magnetic clutch to the battery it kick on no fire at the pressure switch

For the A/C, is the blower motor operating in all speeds?At A/C clutch relay, do you have battery voltage to the D3 and C3 terminals with ignition switch turned on?

For the brake indicator, check the park brake switch. Ensure its wiring is not grounded.
