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. hi there i have a honda accord ex 2002, never had any issue before but two days ago i notice that the blower is not working on the position #1 and also #2 any help will be appreciated…

  2. I would suspect an under or overcharge condition. You could have a faulty expansion valve There are a few other things that could be causing your problem. Do you have a set of a/c gauges?

  3. I have a 2002 Honda Accord LX and it also has a problem with the AC it blowes cold air when the temp outside is under 70 degrees or lower but when its very hot outside it doesn’t blow cold air I recently added coolant but makes no deference

  4. You likely have a loose connection leading to or inside the control panel. If the whole panel is dead like the one in the article, then the panel/control head is likely failing. If everything works except for the compressor coming on, there could be many things happening.
