Hi All,
New member but have checked these forums before numerous times and found them invaluable. Recently had a heater resistor issue, which I followed the guide from LosRubios about changing the thermal fuse and hey presto, it worked 😃😃👍👍
however, I have an issue with my RHS Headlamp and indicator lamp fault (U1A39 and B1D07 respectively). I’ve changed the ballasts and the power modules over between headlamps, but the problem persists, so is this likely to be a control module issue (if so, wouldn’t the left headlamp actuator fail too?) or a grounding problem? I had other minor low battery problems recently, so changed that a couple of weeks ago. Am I right I’m thinking that the ground stud for the headlamp is the one just behind it? (See images attached) Any help or advice would be much appreciated. Don’t fancy spending £1200+ on a new headlamp if it’s not the headlamp at fault, but a dodgy grounding issue.
