RepairPal Certified shops can diagnose and repair your 1999 Volvo C70. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Without looking at the car, it will be almost impossible to say what's going on. Could be the switch itself, but who knows. Bring the car to a Volvo specialist and have them diagnose it.
the convertible works just fine but the switch light is still on and do u know how much its gonna cost me for the diagnostic test?
