Check engine light - code 33?

Code 33 typically indicates an issue with the air conditioning system, specifically related to the A/C high pressure switch or circuit. This could signal that the pressure is either too high or too low, affecting the A/C's performance. It's advisable to check the A/C system for refrigerant levels, leaks, and the condition of the switch. If you're unsure, consulting a mechanic for a thorough diagnosis is recommended.
