Left hand side indicator not working

[Dzk]

so this morning went for a drive and one of my mates noticed that my left front indicator wasn't working, globe and fuses are fine. now i am unsure of what else it could be, also went turning on the left hand indicator they seem to be weak on the back and side. another thing that appears is that all the dash lights start to flash. only thing that I have touched since is the wires under the dash because i was changing a fuse for something else

You have either upset some wiring under the dash (in which case, we can't help you see what you've done), or you have a bad connection either on the 12V side or the earth side of the circuit for the flashers.  These are usually switched to earth at the switch.  I'm travelling and don;t have my wiring diagrams with me to double check this.

Bad earths can cause all sorts of weird shenanigans.

Get the wiring diagram and work it out.
