RepairPal Certified shops can diagnose and repair your 2007 Suzuki Grand Vitara. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
All you can likely do is check the bulbs. Check and replace the bulbs as needed - but make sure you get the proper replacements if you do.
Other than that, you'll need help to test the lighting system to find out what is going on.
