Having problems with your 1985 Buick Riviera ?
I can't get my lights to turn on during daylight only at night on my 1985 buick rivera why?
Alot of the old car have a light sensor behind the grill..take a look..cover it up and see if that works..My old cadilliac had automatic bright light and would flash when i passed anything reflective..so i covered up the sensor. Hope this helps.
