More than likely this is caused by the relays. They are both the same relays and anywhere carries them.
the relay needs to be replaced. you will find it behind the hazard switch (attached to the switch - a long skinny thing) I looked forever till someone told me where it was. Even the Volvo parts guy didn't know and Lawrence Volvo of Walnut Creek, CA would not tell me...
Located inside the hazard switch.
its inside the hazard switch, usually tapping on the dash over the hazard switch will make it blink again
Yes. The relay that controls the turn signals is built in the switch.
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!
It's the hazard switch. I have a 1998 s90 and if you take a small screwdriver and insert it into the bottom of the hazard switch (on the dash) and gently pry it, it will pop out.
First step - check the fuses. Second step - remove the light bulbs from the sockets, and check for corrosion. Clean any up, and apply a little dielectric grease to stave off future problems. Step three - if the first two steps don't help, the flasher relay is defective. You will need to replace the hazard light switch assembly, since the signal flasher is contained within it. About $60 at ipdusa.com.
It's on the Steering wheel. With a hazard symbol on it.

The switch is defective (common---mine is doing the same thing). Emergency fix== pull the 15 amp fuse, but this disables turn signals. Turn signals will work if u hold down the haz. lt . switch at the same time u signal, but buy a new haz. switch, have it installed (too difficult for the avg. driver), re-install 15 amp fuse, and be done with it.
