Thank you! I watched another video, but they did not show how to get the cover off. It was already off. Hats off to you for a very helpful video. :) Update, it took 2 minutes to get the cover off, taking my time. Replaced the relay. Took 1 minute to replace the cover. Long story, hope it helps, I bought the 2007 Accord in March 2021. The third day it did not start on the first try, it made a buzzing sound. Kept driving for several months with my auto tow service. Finally went to an auto parts store, they tested it, said the battery was bad. I believed them because it was a 5 year battery that was over 5 years old. It fixed the problem, for a while, then accasionly it did the same thing. Went back to the auto parts store, they tested it, and sain it was all good. Replaced a bad tire at a shop, they did a free check on the battery, starter, and alternator. They said it was all good. 3 weeks later I was stranded, would not start or even make a sound. My auto tow service said it was the alternator. A.. Simple fix. I decided to tow it to the service shop near me. They ran diagnostics, said the alternator was good, the starter was bad. $830. After the repair, wow! That starter cranked, I could feel , after about 40 starts, one day at a store, turned the ignition, it made a buzzing sound. Tried again, it started. Did some research about relays. Came across your KZbin site. Replaced the relay. Did that solve the problem? To soon to tell, will update after about 80 starts, that should be enough. I agree, if the starter fails, replace the relay. $12. bucks and a easy replacement. Thank you for a very detailed video.

Thanks for the vid. Wife told me AC isn't working in her '05 Accord yesterday afternoon. Asked for details/symptoms and was told "sometimes it works, sometimes it doesn't". 🙄 Checked the car and found the blower fan was not functioning. Watched vid this AM and decided to approach the issue by swapping the rear defog/defrost relay with the blower fan relay. Fan works. Fixed in under one minute. Now the wife has AC (needed in Texas) and I'll get a relay later today the replace the bad one. 👍

Thanks for the explanation, it really helps me confirm some of the relays that don't translate well. Just for the record, these location seem to work for an '04 Honda Odyssey Absolute RB1 (Should be '03 to '08 models and likely the RB2's as well). I have been trying to troubleshoot a parasitic draw issue with mine and I have come to realize that they used the same electrical system as North American Accords since it has the same engine (Yet stupidly has a different air filter). There are at least two other small boxes on my Odyssey for some higher end electrics (Power rear lift gate, power rear seat, heated seats, etc.). I'm not sure if the one behind the Glove box is there, I didn't look closely while I was pulling it apart.

Hi great vid , Im having a problem with my accord it's a 2.2 cdti 2007 , when I turn my car off and lock it after about 10 minutes the headlights and rear lights come on and off the dash also says headlights on and off constantly keeps doing this until the battery is dead , I can also feel and hear a clicking coming from the fuse box also while the engine is switched off , any idea what this could be , I've used a scanner to find any codes it comes up with abs can bus , and also says headlight switch malfunction but I don't know if that means the stalk on the steering wheel or is there a switch elsewhere? Or a relay faulty ? , it has auto light option has its the executive model , if I leave the auto option on the lights don't come on but the fuse box still clicking, if I turn the switch to off then they stay on when the engine is off and locked , it's obviously draining my battery overnight , I've tried a new battery today but still the same , so stressed out with it now , any help would be appreciated

Hey Big Dog, i had a quick question for you about my car. I have a 2005 honda accord ex coupe v6 6 speed manual with 126 k miles. The issue I am having is that i sometimes have a crank no start problem sometimes when the car is warm. I dont hear the fuel pump prime when that happens. The second i shut the key off and try to start it the car fires up no problem. Ive done some diag and replaced all the under dash relays but same issue occurs. I also tried jumping the fuel pump relay when I had that issue and tried starting the car and it still wouldnt start. My assumption is that the ecm is intermittently not grounding the main relay providing power to ignition coils and fuel pump. Any ideas on what might be the issue im having? I did have the ignition switch replaced with an oem honda part due to it buzzing when starting it in the morning.

[@BigDog50001]

Don't forget to check the ECT1 temp on a scan tool/code reader and also scan for any trouble codes. Remember, PGM-FI 1 Relay is for the injectors and PGM-FI 2 is for the fuel pump and they are controlled by engine computer. I would try to narrow it down and see If I was losing only 1 thing (like fuel pump) or multiple things (fuel injectors, fuel pump, spark etc). Intermittent problems like that can be tough and it could be numerous things. If I am only missing one thing then I would tend look at that circuit, if I am missing multiple things then I would probably look towards input signals to ECM (ECT sensor, Immobilizer, cam and crank sensors etc) or for something they all have in common (like sharing a power or ground). Thanks for the comment!

[@BigDog50001]

There are a lot of things that can cause this (relays/air leaks/dirty throttle body/fuel delivery/bad sensors etc). I would start by making sure both Engine Coolant Temperature (ECT) sensors are working properly throughout the entire range without any dropouts or hiccups (cold engine all the way to fully warmed up), especially ECT1. I usually do this check with a scan tool and double check with infrared temp gun. In addition to the ECTs, I will also make sure the intake air temp sensor is working properly too. The engine computer uses ECT1 to help determine air and fuel ratio on start up (and to some degree the intake air temp). One (or both) of the PGM-FI main relays going bad is also a common cause of a crank no start on a Honda (they control fuel delivery as well as some other sensors).

Hi I have a 05 accord coupe. I think all the relays are the same as this. Anyway I have an issue of when I shut off the car, they AC fan keeps running and the light stays on. It kills the battery if i forget to turn the fan off when i exit the car, Any ideas of what may cause that?

[@patrickpk6299]

One more issue I have with the 05 is that I'm getting water inside when it rains. coming in the firewall area somewhere? Usually on the right side, but it was parked leaning to the drivers side, and the water went on the drivers floor board. not sure where its getting in, but thinking air intake (ac / vent /cabin air)? driving me nuts trying to figure out where the waters coming from. I removed the moulding along the windshield and resealed it but thats not it. no sunroof. car has just been sitting, with no ac running. only happens when it rains out. I cleaned everything i could see out of the vents by the windshield / hood (leaves ect). maybe some drain is blocked though (windshield drain)?

[@BigDog50001]

Depends on what is staying on (hard to tell from the comment which component stays on). That being said, bad control modules or stuck relays are common causes of this.

[@gerrybrooks651]

Hey Dave thanks for sharing as it has been quite helpful, although I have a question as I believe it’s a relay or fuse on my 2005 Honda Accord. It sat for a good few months and the battery died (it always has had a small battery draw) so I hooked my shop booster onto it for a while and let it charge back up for a while , tried to crank and turned over slowly for a while, then cut out and now the starter just clicks. I would suspect a starter but the thing is, the car won’t come out of park even with the key on and brake pressed, doors will not lock as well… but I also noticed that it has an aftermarket security system and it doesn’t respond to the key fob now, fuses are good under dash and under hood. Kind of at a loss. Especially when it clicks but doesn’t even try to start. As I don’t want to throw parts at it if it’s some silly relay or fuse that went that I can’t see or don’t know

[@BigDog50001]

There is a good chance there may be an issue with the aftermarket alarm causing issues. I would probably double check all connections at battery to make sure they are clean and tight and would verify battery is good and fully charged (bad/low batteries can cause electrical problems like you describe). I would also make sure the brake lights come on when you press the brake pedal just in case there is an issue with the brake pedal switch.

[@gerrybrooks651]

@@BigDog50001 yeah I found out the starter is on its last legs and had a dead spot on it now that just makes it click sometimes.

Nice video. Which Relay controls the 02 Sensors

[@BigDog50001]

3:40 of the video is the A/F (Air/Fuel Ratio) sensor relay for this vehicle (a 2.4L four cylinder model), it is for the upstream sensor which is a *wideband* Oxygen Sensor on these vehicles. The downstream Oxygen Sensor is a standard *narrow* band sensor and does not have a relay as part of the circuit on this model. V6 models typically have two upstream A/F Sensors (front and rear A/F sensors) and two narrow band downstream sensors (front and rear secondary sensors). The A/F relay controls all sensors on those V6s. Thanks for the comment!

Thank you for the video. Question I gave a 2004 Element with a air horn. The horn now only works intermittently. I had taken it to the audio shop where it was installed and they said it was the clock spring. As luck would have it, the horn worked when I got there. I read somewhere online that sometimes the horn gets dirty and you need to spray with WD40. I did and it worked for a while. Now it has stopped working again. Do you think it’s the clock spring? Obviously I haven’t had a chance to check the usual things. Thanks I enjoy all your videos.

I have a problem with the headlight that won't turn off. Where is the headlight relay located?

[@BigDog50001]

More modern vehicles like this generation Accord do not have standard relays for things like headlights like older models did. The headlight relays (high and low beam) are incorporated into a Relay Control Module which is part of the under HOOD fuse box. The headlights are controlled by a MICU (Multiplex Integrated Control Unit) from inputs from the combination switches, so they are computer controlled. The MICU is usually located inside the under DASH fuse box. Typically neither the relay control module nor the MICU can be serviced separately and if there is a problem with with either the respective fuse box would need to be replaced. The combination switch to the wipers also has a small control unit in it that is part of the circuit. Fuses 1, 3 ,5 and 6 in the under HOOD fuse box should be the ones that provide power to the headlights on this model. Unfortunately problems with the either of the combination switches, wiring, communication lines, MICU, Relay Control Module etc. can all cause problems with the headlight circuit.
