the driver climate zone only blows hot

Hello, It sounds like these issues may both be attributable to the climate control unit (panel), but they may be individual issues as well. If the climate control panel is not sending the signal to the blower motor resistor to run the fan on high, the panel is the issue. However, if the blower motor resistor is receiving the signal to run the fan on high, it is likely faulty. Now, the climate control system uses blend doors to change how much air and what temperature air should blow out of the vents. Same as the blower motor resistor. If the actuator is getting the signal, but does not move the blend door, the actuator or blend door is faulty/broken. If the actuator is not receiving a signal, the climate control unit should be tested, and is likely faulty. You can test these yourself by locating these components on the HVAC central housing, located behind and underneath the dashboard.
