How do I fix the heater control knob?

DTC B2430 Passenger Seat Heater Circuit

Do you know what DTC'S - diagnostic trouble code's are ?

The driver and passenger seat heaters are controlled by the driver seat module. Power is supplied to the driver seat cushion and back heater elements through individual voltage supply circuits. Power is supplied to the passenger seat cushion and back heater elements through a common voltage supply circuit. All of the driver and passenger seat heater elements are grounded by the driver seat module through individual low side drive control circuits. The heater element control circuits are pulse width modulated to ground by the driver seat module in order to control the seat temperatures by regulating the current flow through the heater elements.
Your best bet , take it to a qualified repair shop that has diagnostic scanner that can read this code's

DTC B2435 Driver Seat Back Heater Sensor Circuit

DTC B2440 Passenger Seat Back Heater Sensor Circuit

The driver seat module relies on inputs from thermistors installed in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2-wire sensors supplied with a 5-volt referenced signal circuit and low reference circuit from the driver seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise.

Check the condition of the heater matrix valve under the dash board. Disconnect any motors or cable connections to it and try operating it by hand. If it is stuck, then replace it.

If not stuck, then check motor operation (if climate control model) or cable routing (if manual only).

DTC P0113 - Intake Air Temperature Circuit High Input.The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

I suggest to check wire connections.

Slide down bottom collar on knob, prying with small screwdriver. Under that lower collar is a c clip that pulls out of groove then knob lifts off.

remove two small screws and push it slightly upward . remove the push button first.

If the heater outlet air temperature cannot be
adjusted with the temperature control knob(s) on the
A/C Heater control panel, the following could require
service:
- The A/C heater control.
-The blend door actuator(s).
-The wire harness circuits for the A/C heater control
or the blend door actuator(s).
-The blend door(s).
- Improper engine coolant temperature

sounds like a bad blend door motor common problem. bolted to side of heater box.good luck.

I would say one or both of the the hydralics (one on each side of the hatch) has gone bad. You can usually find replacements at big auto parts stores or order them (EBAY or other sites) online.

Good luck!

I Can Fix It

there is a c-clip you need a small screwdriver to pull it out then gearshift knob will pull off
