Hi Robsta,

Either the backlight bulbs have fused or the wire connectors to them are bad. You need to remove the control and radio to check.

Hi kevinp1,

You mean all the interior lights are not working? Courtesy lights, instument cluster, dome?

Check Fuse # 32 and 33 for power supply with ignition switch turned to ON.

Why my climate control is on the off position and the blower is still running. The air flow switches are working and the temperature control is also working but the A/C won't work. Thank you

It's hot in Atlanta and my AC isn't helping. Hot air blows from the driver's side vents. Cooler air (but not as cold as would be normal) blows from the passenger side. No control mode nor fan or AC setting seems to change this. My mechanic says the AC mechanical system is performing correctly (per his test equipment).

Any ideas?

Thanks for the tip about Auto Zone. I didn't know that they provided this service. However in this case they said there must be no codes since the check engine light was not on. "The AC system won't show codes." Should I have been more persistent?

Due to the complex system you have I recomend you look for an AC specialty shop that is A.S.E. certified. They can diagnose and give repair quote for a nominal fee. Then let me know what the repair is going to be and I can tell what is going on.

Hi twgraver,

I believe it is the air venting system that is not working well.

Over time of usage, the sponge sealing the vents might have worn off resulting in air leakage internally.
This would result in inaccurate air mix for the AC thus different temperature from the vents.

It could also be the air mix control unit that is faulty thereby providing wrong vent opening and closing.

Does the heater work ok?

Does setting the AC temp at different level changes anything?

The wife's 2004 honda accord coupe's heater system operates intermittently. The heater will not put out heat on a consistent basis. The temperature gauge is indcating the engine is properly warmed and the blower motor is functioning, however the car feels as though the AC is on. Took the car to the dealer last winter and they replaced the climate control unit. The heater system appeared to work for a short period, but the problem returned. Took it back to the dealer and their remedy was to replace the blower motor. The blower motor works fine, so we passed on their suggestion. On a few occasions, we have had the heater to work, but not nearly consistent enough to trust it. Winter is here and I am not sure how to remedy the problem. Have anyone experienced this same problem and if so, were you able to fix the problem?

Thanks,
Ron in Bowie, Maryland

Docfixit,

You are welcomed.

For the newer models, not much data is available on AC climate control system.

Hope what I have provided is helpful to twgraver.

Hi Ron,

Possibly the air mix motor is not functioning correctly. Check them for binding and intermittent failure.

I am having the same problem on an '04 Accord. Did you ever find anything on yours? My blower motor and heater control valve are good. I can see the air mix motor and arms moving as I change the temp (above the gas pedal). The motor that changes where the air blows out works (passenger side above where the passenger's left foot would be). It looks like it would be a huge ordeal to remove the box to check that something inside is moving.

Hello,

There are several fuses that run the HVAC system. Here is a guide to help you check them and the heater and air conditioner wiring diagrams so you can see how the system works and which fuses to check below:

Check out the diagrams (below). Please let us know what happens.

My climate controls are not working. They have no power. I can't switch the vents and I only get hot air. I've checked all the fuses in the engine compartment and the fuse box near the driver's side door.

There is also a fuse block on the passenger side, check fuse 13 it is a 7.5 amp with a test light.This is the battery power to the unit.If it is good, your climate unit may be bad, but you would need to remove it and verify power at the unit first

although i've had the car for a few years now, still learning to do a lot of the work myself. within the last few weeks or so, my car has been having some lighting issues. the dimmer switch has been going from bright to completely dark even though my headlights are still on. while I can deal with it, it is rather annoying. I have noticed that if I play with the dimmer switch it will try to correct itself. any ideas for that part? now to my next question. within the last couple of days I've noticed that my climate control lights have been staying on, dimly mind you, even after I turn the car off and remove the key. I did notice that the control knob was broken after I pulled it off. going to order a replacement as no auto parts store around my area carries anything other than domestics. anyhow, this issue has drained my battery on more than 3 occasions. at one point I thought it went away as playing with the buttons got it to finally get it to go away, but alas to no avail. im running out of ideas. ive pulled fuses and visually inspected them. nothing. I know it has to be a short somewhere. any idea? also approximate cost for parts?

Seems like the dimmer circuit is affecting the A/c control as well.
Try puling the taillight relay or fuse and see if the A/c panel lights goes off.

not to sound dumb but where would it be located? I have a Haynes(-_-) manual but it doesn't tell me the locations of relays or certain fuses

Yes, that is the one. Since it did not turn the light off, you would need to remove the A/C control panel and perform testings from there. Check for the source of the power and ensure ground circuits are good.

just for further reference, does it involve me removing my center counsel at all? like for access points? I see where I can pry the rear defrost switch and dimmer switch out. is that all essentially?

Yes, you would need to remove the control panel to test.
