NO FAN

2002 Honda Civic

Air Conditioning problem
2002 Honda Civic 4 cyl Two Wheel Drive Manual 110000 miles

The fan on my Honda Civic quit working during the winter. We bought a new fan but discovered the problem wasnt the fan but the switch (knob) that turns it on. We rigged a switch to the battery so I'd have a fan to defrost my windows, but the A/C does not work at all. We need to know what part we need to make the A/C work. Can you help?

Hi coolmom06,

Let us atart by checking for Trouble Codes. Hope you have not cut any wires to rig the add on switch. Let me know what you find.

HOW TO RETRIEVE A DTC

The heater control panel has a self-diagnosis function. To run the self-diagnosis function, do the following:

1. Turn the fan switch OFF.

2. Press the recirculation control switch and the rear window defogger switch.

3. While holding the both switches down, turn the ignition switch ON (II), then release the both switches. The recirculation indicator and the rear window defogger indicator come on. The recirculation indicator goes off 2 seconds later and the A/C indicator comes on (if so equipped), then the self-diagnosis will begin. About 10 seconds later, the self -diagnosis will finish and the A/C indicator goes off.

If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.

If the system is OK, the recirculation indicator stays off.

Canceling the Self-diagnosis Function

4. Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sure that there are no other malfunctions.

KHLow2008,

I did the test you said in your message. The recirculation indicator blinks 12 times. Do you know what is the problem?

Thanks,

Hi jackcui,

Code 12 indicates a fault in the blower motor circuit.

Are you having problem with the blower not working?

Hi KHLow2008,

Yes, it is not blowing at all. I had a guy checked my car. He did some tests, and he told me the fan itself if OK. But he couldn't do more test because he didn't feel comfortable to open the dashboard. How can I fix the problem?

Thanks,
Jack

Hi Jack,

I will sent the diagnostic procedures to you via email. Here are the diagrams for the diagnostics.
