HVAC issues 06 xc70

[Vaddington]

im needing help diagnosing my hvac issue. It's telling me signal too high/low on lin1. Im getting no cold air and heat only on the passenger side. My ac on button doesn't light up when pressed only the off. And the circulation button isn't lighting either. All other lights function. 2006 volvo xc70 p2 ocean race. Thank you so much. Ive had lots of repairs on it ive done but this one's got me stumped. I tried recalibrating it since I had a battery/alternator replacement but the scanner isn't doing it.

Maybe thermistor issue?
