Parked the car a couple of weeks ago when it started having a hard pedal and dash brake light on. Yesterday I went out to tinker with it and, with no key turned on, when I opened the door the PM unit started running by itself for at least 5 minutes and during that time the radiator fan started running.?????? Finally it all stopped when the battery drained so I turned the key on and nothing- battery was dead. Charging it up today but in the meantime trying to understand what is going on. I periodically had the hard petal and light but it went away until recently. Do I replace the accumulator ball, the switch, the whole unit?
Any ideas?
