I just purchased a 1969 Cadillac Fleetwood 75. The rear A/C has been giving me a few problems. The originial owner had a switch installed(labled-AC--Heat). With the interior (under arm rest) switch in the on position with the thermostat set as low as possible, a little arm does engage and believe it or not the AC does seem to work. Was this unit also capable of heat? The arm rest thermostat does have a 8-85 degree setting and the aftermarket switch installed does have a scribbled heat option next to it. Unfortunately its not putting out any heat nor does the front. Any ideas ?
Also(and more importantly). The down tubes from the outside returns(behind the rear windscreen) attach to the center rear unit(inside the car). They look like they've seen better days. There's a bit of water dripping in. I'd like to replace them but have no idea how to size it or what to use. It looks almost like Unico A/C - Heat residential piping(I used to install it). Although in the center of the down pipes there a "T" for the drains. Any ideas?
I'm glad to finally be apart of the Cadillac world. I also have a 1969 4dr. Deville and 1970 Convt. Deville. I'll post some pics up shortly.
