I have a volvo xc90, driver side res screen comes up white

You shouldn't have to remove the glass. On most vehicles you can remove the regulator from the bottom of the glass carefully so the glass doesn't drop. Then carefully lower the glass into the door. There are plenty Of YouTube Videos ..even if not for your model vehicle all of the basics are the same.

Passenger side exhaust is bank 1 driver side is bank 2. Second sensor downstream of the cat is sensor #2

VOLVO SUCKS

no, That's a firmware issue. You'll have to take it to a Volvo repair shop and have them update the firmware. They should have received a DVD with an update program on it.

no try jumping at switch if still wont work motors bad.

get it into position then silicon it around the edges

you should start by checking your alighnment

You need to remove the upholstery from that side. It is fixed with wide, plastic knobs. Turn them open 1/4 turn and remove the upholstery.

The lights are assembled into a plastic 'cradle'. If you're new to this, only remove one bulb at the time and replace it.

Check to see if you have child protection locks on them if that is the case turn them off? Please rate my response Thank you very much
