One side indicator flash on locking car only

[3.7 slp]

Problem number 2 ..
...please no more...

I noticed lastnight that on locking the car only the right side indicators flashed when I locked the car.
Has anyone had this before and a fix for it. The car locks fine and the red light flashes on and off as always
But just not both sets of indicator lights as before when its locked and unlocked.

Thanks everyone
