Then remove the nut from the evaporator tube and disconnect the electrical connector from the a/c low pressure switch. Unscrew the compressor hose nut off the accumulator and then compressor hose. Then remove the nut (from the evaporator fitting) and the accumulative bracket nut (from retaining stud) before getting rid of the accumulator.
