1994 Chrysler Town and Country 6 cyl Front Wheel Drive Automatic 215000 miles
I have tried to replace the IOD fuse after losing interior lights and digital dash.
The replacement fuse pops immediately upon insertion, even when the engine and ignition are not " on".
I checked with a VTVM, and found a direct short through the IOD fuse circuit, allowing over 25 amps to pass through the fuse socket, thus burning out the 15 amp fuse in that position.
Do you know what could be pulling so many amps through this circuit? My ohm meter says that there is a direct short (showing full continuity) between the fuse position and the battery's negative terminal.
This tells me that something is direct shorted somewhere in the system that is powered through the IOD fuse. I understand that the BCM is powered through the IOD fuse, and thus when the IOD fuse blows, various electrical systems within the van lose power. My dash is out. The radio is out. Driver's door lock works, but unlocks doesn't. Interior lights are out but cig lighter still has power as does heater fan. Any ideas for me, please?
I'd be happy to offer a fee if someone can give me an authoritative answer and solution to this issue.
I am also considering whether the BCM itself could possibly be shorted internally, but I do not know where the actual BCM is located on this vehicle.
