Whats these lights all about

[ste_bla]

Wierd issue with the vectra at the moment..

Sometimes (about 20% of the time) when turning on;

Sidlights = drivers on, pass off
Dipped = side as above and dipped both on
Full = Just both full beam

However when you flash the lights into full (so its full + side) it causes the passenger side light to start after a few flashes!

Also it occasionally. just stops working when driving along!

Any ideas sorry if havent explained it well

dodgy relay? corroded/bad connections?

If it is cutting out, it could be as simple as a contaminated IAC valve. Just pop it off and give it a good blast with some Wynn's carb cleaner and you'll probably be sorted.

As for the headlights, sounds like a dodgy connection in the unit if the sidelight does kick in after you've flashed a few times. You'll probably need to replace it, be about 35 quid from scrapyard.

Would wd40 work or any carb cleaner?

Possibly, assuming its a dodgey connection.

That said, the "stops working" thing could be a bit more problematic to solve. - Do you mean the engine stops working or, the lights?

Replacement with a Mondeo for the Win tbh.

I'm guessing the 'stops working' is the engine - it's a fairly common problem that doesn't take much fixing, and one that dealers will happily gouge you for

Cotton buds and a quality carb cleaner to clear out the sediment and then a good soak in carb cleaner overnight should sort it out. A blast of wd40 on the valve spindle before refitting is a good idea though.

If it is still knackered, you can get them new for around £30 quid from here.

Theres your issue then mate, somethings been disturbed / loosened somehow, check, check & check those connections again.

Carb cleaner & a wire brush can help here.
