Indicator fuse blew due to front near side lens full of water. Dried fitting thoroughly and replaced fuse and bulb but bulb still not working. Any ideas people?
I am guessing as above that the connectors are corroded. it is possible to clean them with a bit of wet and dry or a small file until they are shiny again, but for the price of a new unit I would just replace it.
It is super easy to test. You just need to be logical and work your way through the car. Check you have power at the bulb and check the earth. If it's a no go, move up the wiring and find where it is or isn't working from. You can also check both sides of the fuse, as well as the wires on the stalk like this.
Only takes time and patience. Once you know the problem you can look to fixing it. Having some wire, new connectors, wire strippers and crimping tools can all be handy to make repairs too.
