Where to find the turn signal flasher relay
The flasher unit is integrated into the MICU unit located inside the under dash fuse box.
If your turn signal lever is set to signal position you will get quite a bit of clicking and snapping coming from the column when turning the steering wheel during your turn.
Check in under hood box, Fuse #10 (10 amp)
Where is the alarm fuse?
Fuse box 1 under the hood, number 10
Where is the parklight relay? I have brake lights working, everything lighting except my park lights, checked all the fuse but they’re all good
It is also possible that the problem is not in relays or fuses, but in the lighting system itself or in its individual elements.
2010 honda civic horn relay location ?
Is there any fuse for rear right wheel speed sensor? Because I can’t see any voltage in the connector.
What about the running lights module
What fuse should i remove to disable vehicle while traveling long term? Leaving keys with relative who reconnects battery and drives uninsured. Just want to shut down vehicle from starting without affecting ECU. Thanks
#30 Ignition Coil Relay (under hood relay)?
#23 Starter Signal (interior fuse box)?
I’ve got a question I recently bought a 2007 Honda civic ex coupe 1.8 vtec 8th gen. with a broke rod on number 4 cylinder shopped around for a few months to get a great deal on replacement engine that being said the only engine that is compatible with my car has to have the extra same vin digit in my case my vin starts with 2H sorry for not getting to the point ill get to that in a minute ok engine was local pick up only found on FB market place anywho 2 hour trip just to get it man said that engine vin Infact started with 2H keep in mind year of my car is 07 engine that I bought was out of a 2012 lx 4 door everything looks exactly the same as mine make a short story long I swapped engines got everything plugged in wired up ok my car will crank no start ive.checked everything to do with ecm pgm fi pcm even had on a obd2 scanner only code popped up was the crankshaft position sensor put new sensor on same.thing did I buy wrong engine is my engine compatible or would there be something else I’m on over looking any help will be greatly appreciated
Hllo! Ihave an 2008 ima hybrid 1.3 and i have a problem with secondary water pump. I need help with location of fuse for this motor, or if you can please send a link to wiring diagram for hybrid or the wiring diagram himself? (sorry for poor english)
Ty I fix my turning signals it took me 4m you the man
Agradezco que alguien me dijera donde se encuentra el main relex del Honda Civic 2006 me tiene loco buscando se los agradesco por favor
i am looking to have foglights run with high beams in my 07 honda civic. I cant seem to find the foglight relay. If anyone can help me with that it would be great. Thanks
Hi, where do I find the abs system relay?
Will LX, EX, and other models fuse box work with the Si model?
honda civic cdti 2.2 2009 mirrors are not adjusting or retracting changed sod checked all fuses no36 dont think i am getting any positive voltage to the switch is there a relay hidden any ideas thanks in advance
Civic Si ’06 horn relay location, please.
Damn horn won’t stop blowing. I pulled the switch in the steering wheel, but it keeps going, suggesting the relay is stuck “on”, but it has no listed relay.
The horn has a coupler right behind it: is that coupler also a relay? If I tap the horn itself, it shuts off, but it was suggested that is just me shirting out the connection, which isn’t great.
I have tried making sure the connection is good, but that just results in the ever-blowing horn, which loops back to a stuck relay.
Is the relay part of a combo relay in one of the fuseboxes, or is there an easy solution I am just missing, or do I have to pull tbe entire under-dash MICO fusebox just to fix the damn horn, as I have seen conjectured?
Please advise.
