Hello!

recebtly bought a 2007 Chevy Express 3500 Skoolie.

I have a couple of questions for you lot.

First, I noticed my high beam was out on my driver side front headlamp. I bought a new sealed unit and installed it, I have the same problem! Normal beam fine, high beam, none existent. Is this a fuse issue? Any ideas?

Also, photo attached. What is this pipe coming off the coolant reservoir? I’ve not noticed it before but it’s not attached to anything. Has it slipped or it it for emergency let off so the tank won’t explode?

Thanks in advance.

try swapping the low and high beam relays. Yes check the fuses of course.
that hose is the overflow. It should lead straight down to the road

Fuses now checked. Switched them around for each light and both made my passenger side high beam light up. Still nowt for driver side.

The relay seems to be for both sides high beam, no individual relay. And as one is so should the other? Or is that wrong? As per picture. Loose connection maybe?

Switch 56 around with 58 and see if anything changes

Good shout! Didn’t think about that earlier!

Nope no change.

Still low beam good both sides and high beam only good on passenger side.

grab a multimeter or test light. See if you get 12V on both legs of fuse 44. There should be exposed metal test points on the tops of the fuses.

So it turned out to be the connector. It has corroded on the high beam side.

Replaced it, all working fine!
