indicator, central locking, rear wash
Hi guys
Hope I'm OK to create a new thread, searching didn't quite find the same problem.
I've owned my 2007 Honda Accord Estate (2.l petrol) for about a year now, having bought it from my neighbour at 127,000 miles. It's not in its first flush of youth, but has been a bulletproof workhorse for the family and dog until about a month ago..
We've had an increasing number of minor electrical ****les which haven't individually caused me to worry until last night. First, the central locking ceased to work on the fob, but intermittently. This also affected the rear estate door, where it would not work automatically, again only occasionally. Next came the rear window wash, although the wipers worked. Finally, last night, my son reported that the left indicator stayed illuminated, and wouldn't cancel. Reading the posts leads me to suspect this may be a relay issue, but the multiple diverse symptoms has me doubting that. I have only rudimentary mechanical skills, and am trying to locate a car electrician in a hurry, which is likely to be expensive. I'm even pondering investing in a new R1 relay for the fuse box by the drivers side fuse box, but appreciate I have not much hope of success..
Any help or advice would be very gratefully received!

Ps, checked the obvious things: the battery is new, and good, and the terminals are corrosion-free and tight

I think there's a good chance things are unrelated to each other. For example, the turn indicator cancelling is a mechanical function where a tab in the switch is pushed by a tab attached to the steering wheel.
For the other things, it might be a bad ground/earth connection that serves the circuits for otherwise unrelated things.
You're in the UK, so your Accord of that generation is sold here in USA as the Acura TSX, so that would be where us colonials might look up the circuit diagrams. (I never owned one of those)

Hi Jim
Thanks for your thoughts. I did wonder whether it was a mechanical thing with the indicators, but since I went back to the car today and recorded the symptoms (here -
), the ineffective clicking noises you can hear coming from the interior fuse box area when the engine is switched off do sound like relay or electrical problems, remembered from when I owned a Triumph Dolomite in the 1980's.
I did check the only obvious earth I could find (direct from the battery) - if there are other earth locations and easy instructions, please let me know. The car is in generally excellent condition, with a full main dealer service history to date.
It sounds like any possible fix is going to be beyond my technical ability, so if the advice is to get a grown up to help, I'll understand. As and when I get to the bottom of the problem and the fix, I'll post here.

The TSX and US Accord are very similar, and I own a TSX. I think the TSX is the European Accord Type-R. Your stereo setup looks like the US Accord, so your Accord may be similar to the US Accord and not the TSX.
Has any work been done recently on the car? Any chance that you have an aftermarket alarm/remote starter system installed on this accord?
I see the turn signal indicators are messed up, but how are the turn signals bulbs behaving? Are the left turn signal bulbs stuck on all the time? What happens to the right bulb when you have an assistant hit the hazard button?

Probably very similar, but I don't have circuits for a 2007 USA Accord either...
I was in England several times on business trips, and I never saw the larger car that we have as the 2003 & later Accord. I saw plenty of Accords of different trim levels that were the same size & shape as the TSX. A 2007 USA Accord might have been the biggest car on the road in many places over there.
There will be a lot of different ground locations around the car, each consisting of a handful of wires screwed down to some metal structure. I just don't know which ones serve the circuits that are having trouble in your car.
You can start by checking any fuses that are labeled with anything resembling the functions you're looking for. Fuseboxes in the engine compartment as well as under the dashboard. There will be a battery inside the remote fob, have you checked that?

I just looked at your video, and the indicator problem is not the mechanical issue that I thought. You can check the mechanical function by verifying the lever snaps back to the center position when the steering wheel turns back to straight after a turn. Your signals have the problem even when you snap the lever back with your hand.
It might be burned or sticky contacts within the switch, or maybe a sticking turn-signal relay? I don't even know if those are physical relays or if the flashing comes from a solid-state device by 2007.
It'll be good to have someone verify whether the actual lamps are lighting together with the little lights on the instrument panel. With all functions (right, left, and 4-way flashers) what are the actual front and rear lamps doing.

It's definitely not a type R, and is completely unmodified AFAIK, and no work has been done on the car. Completely 'stock'.
All left bulbs stay lit permanently. If you try the right indicator, the left stays on, the right side activate once, then stop. The same happens with the hazards: left stays on, right side flashes once then cancels..I've had to disconnect the battery, and will attempt to drive it home, under escort.

Since you have problems with several components, I would check your grounds. G501 and G502 on the US Accord are above the driver's side interior fuse box. G601 is under the driver's seat. The US TSX has the grounds in the same location.
The US and UK driver's seat are reversed, so the grounds should be above the fuse box depending on where it is installed on your UK Accord. The ground will have several black wires running to an eyelet or bracket, where the bracket will be bolted to a metal panel. I'd disconnect the battery, disconnect the ground, clean the bolt and eyelet with a wire brush or sandpaper, then reconnect.

Cars have definitely got bigger over here since your time in the UK; we have a thing called a "Chelsea Tractor", big SUVs like range rovers and BMW X5's, usually used to drop a kid off up to a mile away to get to school.
I checked all fuses and they're OK. And replaced the key fob battery.
Update is that I drove the car home today, with a following car to conceal my indicator issues: after a mile or so of driving, the "fixed on" left indicators cancelled themselves, but shortly after, the rear wiper turned on unasked. Central locking also works now. The car is home, battery disconnected..

To me, this sounds like a ground issue. Clean the grounds I mentioned.
It may be very helpful if you found the Honda shop manual for your accord if you plan to do your own work. The US has sites selling the us accord pdf for ~$20. Not sure where to source a UK version, maybe ebay?
