I need to replace the dim only headlight on my 1997 buick riviera passenger side

bad connection or bad earth check all connection or bulb

Sounds like you need to get that replaced. If the metal that the mount is attached to is also rusted you need to get to a fabricator or body shop to have that replaced too.

On a 1997 Buick riviera the light bulbs simply plug in from the back side of the lens. You will have to twist the bulb pod from the socket. Change the bulb,wipe it with a clean cloth and twist it back in.

Yep sounds like you need a new headlight bulb The flashing is the tungsten fillament inside of the bulb breifly contacting the broken halves together when hitting it..Replace the bulb and all should be good. Note some times the light may stay on ,, this is because the broken halves arc welt themselves and break again upon cooling after you turn lights off ...good luck

TEST
remove both bulbs from the lamps but leave them on their wires switch on and see if the bulbs are still different brightness if not they the passenger side lamp housing has damaged mirror is dirty or missalined and needs adjustment. if they are different brightness then this may be a earthing problem.

Yes look at the switch it has a manuel setting.

The power steering pump(with reservoir attached) is on the passenger side of engine on the bottom left side under the alternator.

you just have to recharge you airconditioning unit
