The Digital Control for my cabin air flaps isn’t working correctly. It flashes “horizontal arrows” at the left side and only opens the FLOOR and DEFROSTER flaps. The Fan settings and the A/C buttons work fine. I have a spare known-good Controller, and it behaves the ssme way. I suspect tgere is a floating ground somewhere in the system, but WHERE to look? I’ve been told there is a cube fuse relay located near the driver’s side of the Firewall, but I cannot see it. The only module on the driver’s side under the hood is the Cruise Control. CAN SOMEONE HELP ME WITH MORE DETSILS? Many thanks!
