I replaced a fuse to make the near side, side light work again. But seem to have blown the dipped & side lights on both near and drivers.

The full beams work but only if i pull back the indicator stalk.

Could this be the light switch on the column?
I am guessing that there is some short circuiting in the car as this is not the first blown fuse issue?

The stalk is likely the failure here. The soft metal surface wear out and those symptoms appear. If the fuse is good the horn will still work.

Thank you, the horn still works.
I will get a new one ordered.

what year and model later models have l lighting relay controlling the main and dipped beams which are also fused.
the side and tail are also fused separately the horn and flash are also separately fused so would check before replacing any items

you have the dim/dip relay unless it's been bypassed

Is there a way to test the replay or just plug a wire in to bypass?

test the input voltage on 30 and the output voltage on 87 and check the resistance for short to earth I'm not a great fan of link's unless there is a fuse in the link. swapping the relay for the same is another as the fault that may have destroyed the original may do the same to the replacement ,or be the catalyst for a dash fire if the cabling was or is damaged its time to breakout the DVM

I have tested the fuse in the box and swapped with a known working fuse and replaced the light switch but has not fixed the issue.

Could it be the function box in the drivers side wing?
or the full light stalk?

Have you bridged the contacts to isolate the stalk. I had the same symptoms which led to removing every piece of wire, headlights, and and and very annoying until a kind member on here suggested the stalk as the likely issue.

I have swapped the wires around so that when i push the stalk it keep the full beams on but when i pull back it should be low. unfortunately no luck on the dipped beams.

1 thing i should add i have 2 aux spot lights. could it be the relay in my drivers side wing?

mystery · Sep 14, 2023

have you located and checked the lighting relay and dim/dip relay .are all the side and tail lights working more info less swapping

Strange update.. i must have not done the swap test correct as now when i switched over the cables on the stalk my dip beams are permanently on.
