2009 Eld. Aero Elite, Navi. 3200 chassis.
Doors will not open/close. No stored codes. A&M circuit board not showing any malfunction during testing. RPM/circuit board/motor connections are good, no corrosion, no probed wires. Battery connections are good. exterior key switch for pass. doors has been disconected (had problems with water intrusion causing door malfunctions). Using Navi DLB, switch commands are good, RPM’s have good outputs. By the time the bus makes it in off the road, the problem has stopped, nothing stored in computer, and I can’t get it to duplicate. Any Ideas?
