I have a 2018 Blue Bird Vision that has suddenly lost its stop arm and red light function. The problem is when the driver turns on the ambers, the reds will not activate with the door opening. If you press the W/L emergency button the reds activate and the sign comes out. I tried new switches for both the warning light and the door. Still nothing. I opened the hatch above the door and found no broken or loose wires in the door mechanism. I checked all the 15 amp fuses in the BCM and they are all good. I've run out of places to look. Any suggestions? Thank you in advance!
Ended up being the temporary switch on the door itself. When I ohmed out the terminals there was no change from open to closed when the switch was pushed in or out. Replaced switch and everything works fine now. Thanks guys!
