Why would my air pressure lite, oil lite and blower motor work with the key off on my 1995 peterbilt?

it could be any of the other answers or somebody could have just hard wired those things into the battery or wired it n before the fuse panel|||because you have a live short in the electrical system.one of your relays is stuck open,or it could be the ignition switch is bad and this will also drain your batteries....|||It's either the ignition switch is faulty or a relay is defective. Turn off your night switches until the problem is located.
