I had the dreaded JBE issue for my fuel pump relay- I disconnected the battery, took the JBE out, had it repaired and the boards soldered back together and now I have fuel coming from the tank again. Everything in the car functions as it should...except for my HVAC controls. I have lights illuminating what the buttons do, I can get a light on the interior circulation and rear defrost, but no fan, AC, and none of the dial function. Where do I look? All fuses that appear to be related are good in the JBE. I'm lost.
