indicators not working on LHS

[Nick.S]

Hi Guys,
I have a 2012 transit crew cab tipper which was running sweet as until I towed a trailer at the weekend. Within few miles the LHS stopped working. When I uncoupled the trailer I noticed the towing dolly was full of water!
Since then, NONE of the LHS indicators will light up or flash or illuminate the little green arrow on the dash when asked for by means of the stalk, hazard switch, or the alarm fob .
ALL bulbs, holders, fuses, relays have been checked by myself and 3 other spanner lads.
The RHS side is working fine.
Any suggestions ?

Needs plugged in diagnostics, the bcm may have shut down the output due to the fault on the trailer
