If your compressor is kicking on it might be an airlock in the lines going to the locker

Air lines, if there isn't a leak there and you aren't handy with the tools just take it to a mechanic to save a bunch of time

If the air compressor isn't kicking on check the connections and the switch. if it is then it should have something to do with the lines going to the locker
