Reply To: 58 Merc dash controls
John & Shirley Harvey
Neither the shop manual or the master parts catalog, or the body parts catalog shows any holes other than the ignition and cigarette lighter between the steering column and the radio. They admit that there were air conditioned cars, but do a poor job of showing what the dash controls look like. With non-air conditioned cars, I think the outside air controls were a couple levers on the top of the instrument cluster. Do you see any vents in the fire wall for outside air?
