Low beam on Mazda cx9 issue.

[alexi82]

Hi guys

Jumping on here as a last resort before taking the vehicle to Mazda, in the hope someone may help.

2013 Mazda cx9. Low beam not working on right side. Low beam Working on left side. Hi beam working on both sides

No fuses blown.

Multimeter shows no power to the right hand lo beam fuse.

Checked relay by switching the relay (same relay) with the hi beam relay. Same Issue.

Can't find a wiring diagram but assuming it goes relay then fuse then lights? So assuming issue between relay and fuse?

Any pointers would be greatly appreciated.

Start with the basics:

Does the relay operate?
Is there 12v across the coil connections?
Is there 12v power reaching the relay?

On my car all the lights are driven from separate outputs of the main control unit. It's possible this has a fault.

This is exactly what happened to my car last year. Luckily it was under warranty and I didn't have to pay the bill, which was over £1000 for the parts, labour and reprogramming.

Did you ever find the issue with the low beam? I am having the exact same issue with my 2013 Mazda CX-9. High beam works, low beam does not.
