I’m looking for technical help or recommendations on:
Hello my first post so please be kind, I’ve had my dark blue NC for almost 2 years and it’s be very reliable until last Saturday.
The car is almost completely dead only parts of the car now working is the central locking, interior light, red doors open symbol and flashing led for the alarm. Sometimes the lcd with mileage works and sometimes the red led for the ignition led lights up. So no way to start it or turn anything else on.
RAC came out today confirmed the above and said they couldn’t help.
The battery is perfectly fine, there Power at the main fuse box under the bonnet with no fuses blown. The interior passenger footwell fuse box is only live to the bottom set of fuses but the top set have no feed and are dead.
Any thoughts at all please?
PS I have searched forums already and can’t see a similar issue or way to resolve it. RAC suggested taking it to a main dealer to fix btw.
I’d find a mobile auto electrician. Main dealers don’t see many NCs now - not many people take 8-18 year old cars to Mazda - and they won’t be able to do much anyway, unless the car will talk to their computer.
Also agree scuttle grommets.
Take the glove box out and have a real good look for water ingress.
Very straight forward job.
I good guess the car lives outside?
You said the RAC said they couldn’t help? What did they actually say? The RAC /AA are usually pretty good at sorting out a problem or identifying what the problem is.
Yes guy came out yesterday checked battery main fuse box and secondary fuse box and confirmed what I said in my original post. He did say he’d run a positive feed to the passenger footwell fuse box and the instruments worked but the engine still would not turn over.
I’ve got an auto electrician coming next Wednesday to take a look. I hope he can fix it.
Most advice here and on my pistonheads post seems to be bad earth or water in the passenger footwell. The car is covered so not sure about water effecting the ecu etc but worth a look at the weekend.
I just find it strange that both the interior light and central locking work but nothing else.
The randomness of your problem is indicative of damp ingress so I would start drying out the fuse box area asap.
A friends car would put the headlamps on every now and then all on its own when locked and unattended, answer, damp.
