Headlights Turning Off Randomly - HELP!

[Dm_26]

I was out last night heading out of town going down some back roads with no street lights.

All of a sudden my auto lights decided it was daytime and turned themself off.

Lucky I knew the road I was on and managed to turn the lights back on manually but what I want to know is, is this a common problem or is there a known fix to resolve this from happening again?

Cheers

Re: Automatic Headlights

Never had any problems with mine. I have the auto lights on, but still turn them on manually when i get in the car so i can flash people

Re: Automatic Headlights

Done it again tonight, only when I turned them on manually they never turned on either. Then about 20 seconds later, I could hear the fuse box kicking in and the lights came back on.

Fuse problem? I will replace the fuse tomorrow and see if that helps.

Anyone else had this problem?

Re: Automatic Headlights

Sounds like a relay issue as this is the common denominator to manual and auto lights. Check none have vibrated loose.

Re: Automatic Headlights

faulty relay? doubt its a fuse

Re: Automatic Headlights

Where are the relays located? In with the fuse box?

Behind the glovebox, on the UCH.

Cheers Da, I assume you can't tell my looking at them if they are nackered? Just need to replace it and see if the problem occurs again?

Re: Automatic Headlights

Ok, so the problem has now spread to my wipers aswell.

They only work when they want to work

Is this still a relay problem or could it be the uch or whatever its called?

Re: Automatic Headlights

Could be UCH, but that's the expensive option.

What about a faulty sensor, the auto lights and wipers are both part of the same unit on the windscreen.

Re: Automatic Headlights

Ive flicked from full beam to main beem before and switched to side lights. Fecking sketchy

Re: Automatic Headlights

I don't think its the sensor. I turned the auto lights off the other day, and started the car last night, switched the lights on manually, they came on, 5 seconds later I heard the relay click again and the lights turned off, roughly 5 seconds later it clicked back again and they came back on.

The wipers I turned on and nothing happened. About a minute or so later, I heard the relay click again and the wipers switched on.

Re: Automatic Headlights

Done it again tonight while heading down a dark country lane. Almost hit a tree because of it.

Anyone got any information at all about this as its starting to get quite dangerous

 

[Da]

Does it happen in manual mode?

If not then to be honest I'd start switching them on manually until I could sort out the issue.

More likely a faulty light sensor. Re-pack it. 30 min job.

Go from there. If it's a UCH issue, it'll be a lot more wonga.
