I have a 2002 Honda Civic DX. My a/c heater panel/stereo system got stolen. It seems that the thief stole it clean and plugged out all the wires so that they are still in tact. The only thing that they disrupted was that they pulled off the panel and the hazard lights plug was still in the socket, but the socket was ripped off the panel and they cut the antenna line. When I bought another a/c heater panel, and installed it, the hazard/blinker lights turn on, and the defrost turns on automatically once plugged in, and then nothing else on the a/c heater panel works. All the lights on the a/c heater panel don't work (i.E. Turn on a/c buttons, a/c switch & defrost switch don't work, etc, only the hazard lights switch works fine). Do you know my problem to fix? I read a little and could it be that fuses are blown or my a/c heater panel is not grounded anymore (where is the ground) or something else? I believe its a small problem, as the a/c & defrost worked perfectly fine before stolen. I thought it may be a bad a/c heater panel, but I got another one, and the same things work, and the same problems (hazard lights work & defrost turns on at plug in, but none of the other switches/lights turn on/off). Please help! Call me direct 808-497-9367 or email me kkobylanski@firstam. Com or reply to this post. Thanks so much!

Hi Hawaiian 1107,

Thank you for the donation.

Underdash fuse # 14 ( 10 A ) supplies power to the control panel and since the defrost light is indicating, it means power supply is good.

To test the ground circuit, use ohmmeter to test for continuity between terminal # 13 and body ground. Grounding point is # G502, located under middle of dash.

Attach a remote wire to terminal # 13 and check if the panel works when ignition switch is turned on.

Is the control panel confirmed to be correct for the model?

Thanks! I will check all fuses are all good. However, you may have misinterpreted what I said. None of the lights on the a/c heater panel works. What works is the Hazard Light Switch, and it seems broken but the defrost automatically turns on when you insert the plug (you cant turn the defrost on it just stays on). Do you know why I would not have power to turn on/off any of the light buttons (a/c, defrost, car circulation buttons) or the knob switch controls?

How do you check if the control panel is confirmed for my model car? I just went to a mantling shop to get the piece, and I told them my exact car and they gave me a panel that looks exactly like my old one, and they brought me two panels as I thought the first one was broken, but then when I tried another one the same things worked/defrost on but cant turn on, and no other buttons or switches worked. So I presumed the panel is not my problem, something else must be it.

I will switch out all the fuses, and I will install the stereo maybe he knows where the car ground is as I have no clue, and maybe he has ohhmeter to test.

After that then I think I have to go to a dealer to see if they can fix.

Let me know if you think of anything else?

Thanks again!

The defrost is part of the control panel so if the main ground circuit is bad, the system would try to ground itself through any other possible means and it could be through one of the components link to the control panel. That would cause the defrost light to be turned on.

Try a remote ground circuit to to terminal # 13 of he 14 pin connector and check if the control panel works. Without proper ground, the control panel would not work. Inspect the wire harness connector for damage or shorting.

I am not sure how to go about checking the control panel to be correct for the vehicle.

If power supply and gounding are good and control panel does not work, it should be the cause. Such panels are known to go bad even in storage as there are capacitors in the unit that can leak over time.
