Hazard signals not working and turn signals not flashing in '99-00 Volvo S70's. How to fix?

Answer

The turn signals operate through the Hazard switch. The Hazard switch assembly is in the radio console inside the car and must be replaced. This unit is about $90 CDN and can be purchased from the dealership.

I replaced mine by pulling out (Carefully!) the radio console (the owners manual will show you how to do this). After that, you:

Push the old Hazard Switch out from the rear of the radio console.

Unplug the wire at the end of the broken Hazard switch.

Plug the wire into the new Hazard switch.

Push the Hazard switch back into the radio console and slide the radio console back in place.

It takes 2 minutes if you get someone to hold the radio unit while you change the switch. Good luck!
