2008 Saturn Astra XR 4 Cyl 1.80L
Body & Interior
Dash lights go out and headlights dim when i turn windshield wipers on this is an intermittent problem
Lights only go out briefly I had the ignition housing replaced but it still happens
Sounds to me like the wiper motor is taking too much load, unhook the wiper motor and switch on the wipers and see if it makes any diffrence, if it does then change the wiper motor.
