2005 sirion 1.3 Auto. After plugging in trailer electrics to tow hitch plug , first the right side indicater didn't work then after trying hazard lights both indicater lights and hazard lights on the car don't work. I have checked the fuses but they seem ok, I can't find a relay for the indicaters or hazard lights.I wonder if it has caused some other problem . Dave Problem solved. I took the car back to Western Towing in Newton Abbot and after locating the fuse that was in the passenger side glovebox area the problem was solved.No charge Western said the tow bar had a lifetime guarantee, great service!
