Today I turned on my heat . 2015 base Boxster. Driver side blew hot air, passenger side blew cold air. The console button marched air off , light was on. Both sides temps was set high. What am I doing wrong?.

Thanks for you help

If you have a two zone HVAC system, each side (driver/passenger) has a blending door which mixes hot air which goes thru the heater core with cold air which comes from outdoor (in the heating mode). If the passenger side blew cold, either the blending door is physically stuck with the cold air side open or the temperature sensor or the door actuator on the passenger side is defective. Could be something else, but those are the likely suspects.
