Honda Civic del Sol A/C and Heater Controls
The Honda Civic del Sol’s climate controls are more complex behind the dash of your vehicle than they appear. When something goes wrong that prevents the heater or air conditioner from running properly, the fault can be anywhere between the switch and the heater or A/C. You can find the Honda Civic del Sol A/C and heater control you need and learn more about them here.
How do the Honda Civic del Sol’s heater and A/C controls work?The climate control panel controls the mix of cool and warm air entering the cabin as well as the blower fan’s speed in your Civic. Behind the control panel, a cable is pulled that adjusts a valve to direct the amount of desired air from the heater core or air conditioner. The blower fan’s speed is controlled by a switch and relays that adjust the voltage to the blower motor.
What parts are involved with heater and air conditioner controls?The heater and air conditioner controls include:
- Climate control panel
- Control cable
- Cable bracket
- Heater valve
- A/C compressor relays
- A/C relay connector
The blower fan controls include:
- Fan speed switch and knob
- Blower motor relays
- Blower motor resistor and wiring
- Resistor connector
- Blower motor fuse
Diagnosing climate control problems can be complicated because there are a number of components that can cause an electrical or mechanical failure as you drive your Honda Civic. Here are a couple control panel problems that are common in the Honda del Sol and other vehicles:
- Blower fan doesn’t turn on: When the blower fan won’t run in your del Sol model, it can be a faulty blower switch on the control panel that is the problem. If the switch wears out, it will fail to create a circuit that turns the fan on and sets its speed.
- Temperature control jams: The temperature control on the Civic del Sol pulls a cable that opens and closes the heater valve. If the cable comes loose, jams, or the valve control is obstructed in some way, it will be difficult to move the control lever.
The climate control panel can be removed from the Honda Civic del Sol’s dash and replaced as a unit. Follow these general steps. The details may vary depending on the year your Honda was made.
- Disconnect the car’s battery by removing the negative terminal.
- Remove the stereo, sliding it and the metal cage that holds it out of the dash by bending the metal tabs that fasten them in place.
- Remove the instrument cluster to access the climate controls. It’s held in place with screws on top and underneath the clock.
- Release the cable that is attached to the climate controls.
- Slide out the climate control panel by removing the three screws holding it in place and disconnecting the yellow and green wiring plugs.
