Alright so recently my climate control button to blow the amount of air has stopped working recently. It worked fine a few days ago and now, if I switch it to 1-2 out of the 4 it doesn't blow anything. It only starts blowing my a/c or heater while on 3 or 4. Could it be a wiring issue? And on an unrelated issue, the lights for the whole a/c system don't work unless I hit a bump then they'll turn on. Another wiring issue?

This is probably a burnt out resistor. The resistor is in the top of the ductwork behind the glove box. You should also pull the fan and check for a mouse nest in the duct. The resistor needs airflow to keep it cool.

The panel lights could be a bad bulb or bad solder connections in the panel. Either way you need to remove the panel from the car. Resolder the circuit board and install new bulbs.
