I left my sunroof opened and after a heavy shower the inside got wet.

I'm now getting a HDC Fault a few minutes after starting the vehicle and when i change gears I get a transmission fault. Also, I can raise the vehicle, but not lower it. After speeding up, the vehicle will lower itself.

I took apart the center console vacuumed the water and left it to dry for the day, but it hasn't helped. Everything seems to be working (terrain select, Hi/Low range). I can change gears. Only issue is the errors and the inability to lower the vehicle.

I read online I need to change the control switch assembly to fix the issue with suspension, but I'm not sure what's causing the other issues. Grateful for any help.
