This car has the driver and passenger tempeturer control for the heater and A/C. The passangers control works in either mode but the drivers only works when the A/C is on, when the heat is on it wil only blow cold air even when set to full hot.
The heat only works on the passenger side from the dash vents, but cold from the driver side dash vents, defrost, and floor postions.
the heat on the passengers side blows hot but the drivers side heat blows cold, I also noticed that the light behind the drivers side of the temperature panel is out does that mean its the panelthe heat on the passengers side blows hot but the drivers side heat blows cold, I also noticed that the light behind the drivers side of the temperature panel is out does that mean its the panel

The main issue with this is either the thermostat or the climate control switch I do not know if your climate control switch is electronic or manual either way I would start out with the cheapest and go with the thermostat first good luck!

The heated seat system consists of the following components:
• Driver and passenger heated seat switches
• Driver and passenger seat back heater elements
• Driver and passenger seat cushion heater elements
• Driver and passenger seat back temperature sensors
• Driver seat module
• Driver door module
• Passenger door module
Do you know what a electronic module is ?
DTC B2425 or B2430
Circuit Description
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.
DTC Descriptors
This diagnostic procedure supports the following DTCs:
• DTC B2425 Driver Seat Heater Circuit
• DTC B2430 Passenger Seat Heater Circuit
Do you know what a DTC - diagnostic trouble code is.
Heater or mode door actuator bad , possibly ! You can look on youtube for videos showing how to change . It can be easy or very hard to replace . You could have it checked for DTC's diagnostic trouble codes stored in the heater control head . dealer only !
i've been down here too myself, and discovered that the temp control motor, located in the bottom of the glove box, which you can access by clearing all your stuff in in and opening a small door. you can adjust it manually, and see if it changes, if yes, the switch can be defective, as well as the motor, the switch is the most likely problem. but adjust it manually first.
This is usually a problem with the passenger seat heater control module. It is a common failure on your vehicle. The module is part of the seat cushion.
Just for the heck of it though, check to make sure the wiring to the module under the seat is connected and not loose.
Check the passenger side mode door actuator. This is located under the dash on the passenger side. Once you find it watch the rod as you move the temp lever from hot to cold to see if it moves. If it does make sure that the rod is hooked to the door. If it doesn't the actuator is probably bad or the door is jammed.
The blend door on the passenger side has broken. Jeep has made a replacement section for the heater box assembly so you don't have to buy the whole thing. You will need to remove the heater/A/C box to replace the part. I have done quite a few of these repairs to fix the problem
There is a motor that operates a door to change the air temp to the drivers side based on the setting of the temp control, it is called a blend door motor, there is a problem with the motor or the blend door is jammed and can't move.
the heat on the passengers side blows hot but the drivers side heat blows cold, I also noticed that the light behind the drivers side of the temperature panel is out does that mean its the panel
