As im snowed off i might as well have a look at this shit van ive been lent.
The back lights flash when the indicators are on, bad earth? Where do i start? x plate transit.

 

Sounds like the Earth , or bad connection at the plug . Is it wet ? Dose it do it both sides ?

 

does it both sides, only when lights are on!

 

Cheak the Earths they will be brown or black there come off the loom at the back were the lights plug in . Phillips screw or torx 25 i think ,prob rusty round that area 'lol'' clean up the connector and the body were it screws to first . Have you cheaked the plugs ?

 

Not had a look yet. Going to have a go in an hour. Cheers for the pointers.

 

No worrys , hope you get it sorted .
