Hi Guys,
I have a little problem with my Gn's Power master cylinder pump motor. I changed the accumulator Friday. I changed the pressure switch tonight but the pump motor does not turn on and cycle. When the pressure switch connector is plugged into the pressure switch and when i plug in the connector to the relay of the pump motor, it makes a click sound but nothing turns on causing the brake light to stay on at all times and pedal to remain hard. I think that the pump relay is burnt because of the clicking sound as if two connections are in contact. Please help me out and give me some feedback. Will probably buy a new motor

Thanks guys!!

If it is clicking, the relay is probably fine. The motor is probably shot, or you blew a fuse.
 
Brake motor

Hi guys,
Still concerned about my brake problem. The fuses are ok, the terminals seem ok. If it was the motor, would the symptoms be only blown fuses. If the fuses are not popping, does it mean that the motor can still be shot in other symptons??
Guys....I could sure use some advice on this matter from a buick guy

Thanks. Please let me know

Mike:rolleyes:
