Long story short... 06 LR3 HSE. Radio volume works 20% of the time. Comes on randomly. When it's not working, it's almost like the radio doesn't even recognize the knob - it doesn't say "Audio Volume" or show any of the volume numbers like when it's working. Pooling water in passenger footwell. I have replaced passenger sunroof drain, warped windshield cowl and blew out both AC drains. It's drying out slowly. Question...could the water be affecting my intermittent volume issue or does that sound amp or software related?
