2005 - s80 High Beams wont stay

Is the headlight switch in the correct position the knob should be pointing up not towards the drivers door on a left hand drive car if it is in the correct position does the radio controls work / wipers work /turn signals work ?? if these do not work then most likely the steering wheel module has gone south & is not coming back post back & advise on these questions that I asked so i may be able to assist you with the correct diagnoses Glenn K Volvo Certified Technician ASE Certified Technician

Yes, this is almost cerytainly it - took me six months to work out why I couldn't get high beam locked in on our v70. It's a silly system.

How else would you implement DRL v/s HL?

Don't know what those are. Apart from disabling/enabling the fixed high beam, what else does the two headlamp settings do?

yea...make sure the headlights are "ON" and not just on DLY status.....i fig the car may use different bulbs for DLR vs. actual headlights....
