Brand new to me owner, 2006 Land Rover Range Rover HSE. A couple issues it has that are plaguing me.

1) A/C is warm. We charged it, it was only slightly low. Didn't make a difference. Can drive 30 miles, no change, just luke-warm, not hot air. Can key cycle and may get better, but never right. Suspect some sort of blend air door issue? Are there any ways to test or reset these through the hvac panel, pull fuse, or any tricks? Anything common?

2) Sirius won't work. Shows no subscription. We subscribed, refreshed. Only stays on channel 4, no sound. No ideas, maybe satellite module or something disconnected?

Really appreciate any help, my wife LOVES this thing, but has a few glitchy issues on a well taken care of vehicle.
