2002 Honda Accord A/C Controls Inop

This 2002 Honda Accord came in with the complaint that the blower worked but nothing else on the a/c control assembly worked or would even light up. I started by checking the #3 fuse in the driver’s side interior fuse box (7.5 amp) and the #13 fuse in the passenger side interior fuse box (7.5 amp). Both fuses were good. Time to remove the a/c control assembly for testing of the harness. First I removed the two lower retaining screws.

Then I used a small screwdriver to pop the clock and hazard switch assembly from the dash.

With the panel removed I could now access the one hidden screw and pulled the panel with the a/c control assembly out of the dash.

I then removed the control assembly from the panel.

Then reconnected it to the wiring for testing.

I had to disconnect the control assembly to get better pictures of the wires. First I checked for ignition power on the black/yellow wire at position 2. Good

Then I checked for battery power on the white/yellow at position 3. Good

Then I checked for continuous ground on the black wire at position 9. Good

  1. I would see no need to worry about the battery if you are not having starting issues. If the lights work, the blower only works on high and the air is hot, I would suggest you concentrate on one issue at a time. I would start with the blower issue if it were me.

  2. I have this problem also in an 02 Honda Accord EX Coupe 3.0 6 cyl, except the fan blows hot air only on the high setting when the AC button is on but all the lights work. If my test for the battery wiring is not ok does this mean I need a new battery? After I checked the fuses, my father asked me, “how old is your battery?” (it is almost 3 years old and it has been really hot here in Texas. . .over 34 days of over 100 degrees). . .this is why I ask. I called a Honda dealer for parts and they claim I need the whole assembly and it cost $665.00–which I do not have at this time and it is 106 in Texas.
