... dealer and they replaced the oil sensor so now the check engine light is off. The dealership also said that the mode actuator is the reason the driver side is blowing heat. My issue is that it's hot 100° + outside and I can't go anywhere without airconditioning. Now my air conditioner is blowing hot air and my car is going towards the H (trying to run hot) do you know if it's the actuator or the thermastat? Please help!!!!!
