Is this unit not big enough or is something wrong with it? Another question. At one time something was mounted behind drivers door and in front of rear wheel. looks like ac lines ran to it. What used to be there? And finally can someone point me in the right direction to get info on original Ford ac on this bus? Diagrams or any tech info would greatly be appreciated. It doesn't work right now but my Father-in-law is working on it. Thanks for any help.
Boy-I feel your pain (stuck in traffic yesterday with no AC @ 95*)
If you bus is set up like mine, when the bus was built up from a partial chassis, they disable the stock AC + run the rear AC unit in series with the stock stuff.(mine has a sticker on the dash "rear AC must be on for the front to work" does yours have something like that?) My stock condeser sits never used in front of the radiator-the whole system ran thru the big condeser under the bus. (from behind the driver to the rear wheel) I eliminated the rear AC and am trying to get the parts to hook just the front up.
Is the roof top unit a stand along unit?
