new member ,,hello

hello guys , i bought a2002 TD5 defender 110 pick up in november ( my third ) , and i am loving it
Ive had a stage 2 remap from stormtuning and if it hadnt been for the snow , i would have had a 2" lift and new tires and wheels fitted lol

ive a small niggle with my window wipers , they wont stop until the engine stops , ive changed the park switch and the relay but no change

can anyone advise ?

thanks brian

Column switch is likely.
