View Full Version : Air Operated Door Lock

05-17-2014, 07:59 AM
The air operated door lock on my bus has stopped working. I recently was replacing the updated outside door handle for XL II and realized the air lock at the top of the door was not working. As I recall, it would lock and release with the action of the emergency parking brake - apply brakes lock would open, release brake and lock would close. Can anyone give me any clues as to what the problem could be? Thanks.

I also have a switch in one of my bays that turns off the lock. I assume that is in case it gets locked while no one is in the bus. If you have a switch, could it have been engaged and you didn't realize it?

I have an override switch and have tried it in both positions and nothing happens. Thanks Dale.

Do you have a set of breakers in an upper door under drivers window, if so look at diagram and check for breaker or a pull down box to check, ?
