When I turn the AC on the passenger side of the car continues to give hot air.

I believe it s in the temp control mod which moves the duct door from the heat side to the a/c side.

Drivers side is cold? Possible 'blend door' or 'mode control' actuator. Climate control may have a 'self diagnostic' mode. Try alldatadiy.com for more vehicle specific info. Also , depending on the system layout , it could be low on refrigerant.

Hello your problem is the heater control valve i had the same problem purchased a new one for 138 don't go used you were just have the same issue.
