Major electrical problems

[Oarsman]

Hi all

Having a problem... car still running BUT ...

 

Tailgate opening button not working from outside (electrically) but can open manually from inside

 

Passenger left front window not working

 

Wing mirror left passenger not working  and heater demist system not working

 

Flashers not working when locking / unlocking car

 

Note: these electrical problems above have been seasonal for the last 5 years - i.e. warm periods NO PROBLEMS AT ALL and then colder / wetter periods THE PROBLEMS APPEAR suddenly

 

UNTIL this summer when the problems persisted

 

Anyone recognise this set of issues and any potential remedy?

I am having it looked by a dealership next week

Hi....welcome to the Forum

 

Certainly sounds like water ingress in a body control unit.

Alternative thoughts are maybe it could be some wiring in the tailgate area so when the tailgate opens and closes it breaks the wiring in the loom which connects the two.
Can give loads of strange faults, easy to check and repair though

 

Let us know how you get on with it

Thank you Trevor - much appreciated! I'm going to Reading Honda garage on Wednesday so this information is excellent and does fit with some thoughts I was having. best regards Carl

Fixed. It was a relay in the front passengers door - this was replaced at circa £200 and rectified all the electrical issues!

Relacing bulbs in headlamps also a pain to do, Honda did this for me actually.

Reading Honda have the details if anyone is interested - James is the contact.

Now onto fixing the particulate filter which won't re-generate now ....  quite expensive to replace as you will all realise.

Glad to hear you have a positive result with not too much cost involved.
Interesting to know it was a faulty relay at fault.

 

Good luck with the DPF...there are companies that can pressure clean them off the car and this will be a lot cheaper than a replacement item.

Let us know how it all goes.

Hi Oarsman

 

Have the exact same problem with my electrics.

You wouldn't have the part number for the relay or the exact location of it.

Woud it be the switch for the passenger side window?

 

Any help would be much appreciated.
