Passenger/driver split temperatures intermittent/second teeny

I am assuming you are not getting heat/cold out of one side of heater. try pulling heater fuse with key on for sixty seconds they will reset and that may be the problem. otherwise it can be something with the auto temperature also causing it. I will send a picture of actuator. however, the tire pressure if a monitor has to have the tire removed so they can get it out, it is below the valve stem. you can also try a reset on that if tire is full If you still have your manual it will tell you how to do it. to replace the actuator you have to pull the HVAC unit out which means the dash. so it is probably not something you want to do.
