Had in car pushbutton not working (placing a car call) on an LRV 3. Didn't have a replacement board handy so i swapped the assembly with the adjacent rear floor pb (never used) but that didnt fix it.(the old board worked fine on the rear entrance). Car is running but will not travel to level 3 front.
Im thinking processor board? Any thoughts?


Found an identical (so it appears) hall pushbutton board in the shop and i gave that a try (why not its monday).
When i energized the controller i could smell the familiar smell of burnt resistor from the cop and now have a lifeless cpu. There is a flashing red light on the processor board and a quick check of controller fuses didnt show anything obvious. Any thoughts?
