Question about 2004 Honda Accord

2004 Honda Accord LX A/C

Unable to turn on a/c, when max/ac or a/c button is pushed the light does not come on. The fan does not come on either, even if you turn the knob to adjust the speed of the air. It was working at noon yesterday and by 2 it would turn on and then cut off suddenly and within 10 minutes wouldn't turn on at all. HELP! I live in Southeast Texas and its hot and I have a 6mo baby!! Thank you for your help!

    I'm having a similar problem. Last Saturday my a/c was working fine. I went shopping and got back in the car and no air would come out. Then all of a sudden hot air came out for a minute or two and then it stopped again. Then hot air again, then nothing, and then cold air the rest of the day. I thought maybe all was just a fluke. Next morning, no air at all. I was first told that it was the blower motor, so I let them put one in. That wasn't it. Then I was told it was the control head, so I prepared myself to pay the $1000 to have it fixed. Now, they aren't sure. It could be half a dozen things. I have to take it to the dealership tomorrow, which I hate to do. They have said by phone it could be the control head, or the whole radio system. Could be up to $2,900 to fix.

    I have the similar problem. Sometimes, when I turned on the A/C, no cold air comes out. But it did not happen all the time. Actually, most of the time, the cold air would come out. But then once in a while, A/C did not work.

    I have not taken it to the repair yet.

    check to see if the air con fan is turning freely.....it may be partialy siezed and blown the fuse if it is not turning freely try spraying a penetrating oil at the motor spindle to free it off,i had a bmw that did exactly the same.

    Yesterday my 2004 Accord EX 4 cylinder, manufactured 09/2003, at 60000 miles had the exact same issue. Wouldn't come on in th emorning. Came on sporadically for sometimes 2 minutes then off for hour. Come on 30 seconds off again. Today while driving to work wouldn't come on when car started. Came on for about 15 seconds after about 10 minutes and then again no workee.



    After researching this via the interent, it appears that many Accord owners are starting to have this issue. Ask around if you know other accord owners. Let us know your model and current mileage date of manufacture (open drivers side door and look on jamb towards the bottom). It might be a lot issue and cause for recall or out of warranty repair by manufacturer.

    I have a 2004 Honda Accord EX with problems as well. I have about 57,000 miles on it. The A/C, fan, heater, and defroster aren't working. The lights come on, but there seems to be no power.

    I think this is a factory issue and they should do a recall to fix all these issues if so many people are having the same problem. I hae the same issue where my dash board radio screen ha sno light and a/c, heatings buttons do not even work at all. The over head light does not come on and te bulb is not blown and the seat heating buttons do not work either.... This is an issue an i am sure there are people that are probably just bringing there cars to get diagnosed and know one has a clue. When i called the honda dealer to ask bout the issue they gave me the run around and said it can be anything and that it sounds like and electrical issue. The must already know what it is if so many people have the same issue. Instead they wanna charge me for the T/S and then charge me to fix what they think it might be at $90 an hour for labor...

Had the same problem. Try changing the blower motor transistor/resistor FIRST. It's easy to access behind the drop-down panel abover the passenger side floorboard. I made the mistake of taking my Accord to the local Honda dealer. I was told by the service tech that both the transistor/resistor AND the blower motor were bad. $585 later, I went out in the shop and talked to the mechanic that had worked on my car. He said the blower motor worked but they went ahead and replaced it "just in case". I told him that was fraud and that was not what the service tech said. He turned white as a ghost. Going to report this to Honda.

Took my car to the dealer today. Took them about 30 minutes to T/S. Determined that the blower motor had a bad power transistor. Took about 15 minutes to fix. Cost was 83.37 for transistor and labor was 178. These are Hawaii prices and I know I could have done it much cheaper had I a clue. A bit high but only took one try to repair and the repair has 12 month warranty.

P/N of the transistor is 79330-SDA-AO1. Located in passenger side foot well.

If you go to estore.Honda.com and look under Electrical/Exhaust/Heater/Fuel, click on Heater Blower for the 2004 accord, it will be item 11 in the drawing.

Hope this helps.

I had the same problem. i have a 2003 honda accord v6 4dr. no air comming from the a/c or heater. i check several forums. i replaced the power transistor ($70-80) bought part at dealer. it is located at the passenger firewall. it has a 4 wire plug, and attached with 2 phillip head screws. 1st take down the panel right underneath the glove box so you can see it. then unscrew the 2 screws and unplug. pull out power transistor and replace in reverse order. once you screw it back in, and plug it back in, then you can start the car and test the heater and a/c. (You do not have to unplug car battery). dont forget to put panel back up underneath glove box. should take 10-20 mins. Tools i used: a panel door popper, or flat screwdriver, small drill, angled bit, with a phillips head tip

Had the same problem on my 2004 accord. Its the resitor that controls the fan blower. It under the dash on passenger side. Remove the cover and you'll see the wiring to the blower. The part is secure with two screw. The part cost me about 90 dollars thru the dealer. Its work since. Hope its also your problem.

Jump air compressor ac works replace relays same issue HONDA


the compressor may be low on freopn but, the fan problem is most likely the fan motor as it is the low temp fan and will run more often than both fans...to test see if you can switch the fan plugin to the other fan watch carefully that it does not get too hot as the second fan is a safety fan that works as high temp or when using the A\C

1991 honda accord lx cooling fan


Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine. This can prevent hard starting that can happen with a hot engine. If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing. Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.
