Hi there . I just got a 2011 astra van 1.7 it has a constantly showing message on the dash for parking brake . All bulbs are ok . It seems someone has connected the left parking light to the right . So when the van is off and I put left indicator on both my front parking lights are on .then when I put right indicator on I have no parking light on at the front . So I take it it's a wiring problem can anyone give advice on where to start or anything I could try to get this message off. Thanks .
