How does the A/C compressor clutch failing cause the auto headlights/wipers or courtesy lights to not function? I've never heard the corelation between the two made before. Just curious.
Fuses or modules are a definite possibility. Talking about auto on items, The auto wipers work off a sensor as well as the auto head lights. Maybe there is a sensor malfunction.
Fuses are the most simple so check those first. It's probably something simple.
