My Volvos speedometer quit working and the ABS light is now on. my signals will sometimes work and sometimes not. the same as for my front left headlight. I foot understand what it could be or what I need to do! please help! Thanks!

 

Does the speedo work off the same sensor that detects wheel movement for the ABS system? That would explain why both problems exists. Can anyone confirm?

Please explain more for the headlight? Is it burned out? Did you replace the bulb?
