It seems that when the bumper was replaced on my 95 960 sedan, the shop said the horn contacts were corroded, so they removed the horns and put them in a box in the trunk. I plan to clean the contacts on the horns, replace the clips to the wires on the 960, and then replace the horns. Where are the horns located and how many are there? Any advice on this would be appreciated. I feel unsafe not having a horn.
