My trailblazer ext came with rear ac/heat and the fan randomly comes on. I can’t get it to stay on. I use the front main control to try and turn it on and nothing. Try and put it on rear control and use them and still nothing. Any tips will be appreciated

My AC works to a point. However, when I turn on the vents, nothing blows out. If you put your hand up to them, you can feel cold behind the vent but no airflow. I have airflow at my feet and windshield but not the vents. I am rather car illiterate so any help or tips are appreciated

The back lights behind my RPM gauge are completely out and part of the ones behind the miles per hour. Also random buttons on the radio and AC are out as well. I don't think it's a cluster issue otherwise it would be the whole thing and not just certain buttons.

The engine starts, the car moves but no power in ac, windows, lights. We replaced burned/damaged BCM. Before we replaced BCM, headlights and brake lights working. You think the shop damaged my BCM? Because it seems the problems styes even after installing new BCM. Thanks.

Turn bright lights on truck dies now no air conditioner or blinkers no low beam but can run high beams only
