vr6paul 0 Posted August 4, 2016 Folks can someone help diagnose? Spoiler works off the switch and speed sensor no probs until I turn side or head lights on , then it goes down (regardless of car speed). If put it up again manually it stays up until I switch headlights off (back to side lights) then it goes back down again. Am I crossing wires behind the dash somewhere????

Supercharged 2 Posted August 4, 2016 The spoiler module is fairly close to where the headlight loom runs... I would check this in case the Earth on that loom has burnt out - this can happen with headlight switch failure and many of us have fitted a fuse on this wire to prevent this happening. Usually it's connecting the speed sensor wire on the stereo that causes the spoiler not to work! Quote Share this post Link to post Share on other sites
vr6paul 0 Posted August 4, 2016 Should I be fitting an inline fuse on the headlight loom? I'm guessing black being earth? Have taken it to pieces and no obvious bare wires etc but I can't recreate the problem so maybe something was touching Quote Share this post Link to post Share on other sites
