That sure looks like an overflow tank of some kind, never seen one.
The round blue & cream color rectangular containers are charcoal canisters, fuel tank vents into these, have zero to do with A/C function.
The round, black "can" under blue tank is the A/C vacuum reserve.
Thanks KC! I am assuming that there is a missing cap on the left side as you look at it?
There is a flexible hose that attaches to fitting and goes to side of air cleaner housing........
Do you still have the original air cleaner assembly?
If your air cleaner assembly still has the fitting for attaching the flexible hose to fitting on charcoal filter unit, you can probably use any tubing (rubber or vinyl) so long as ID is correct, it is not under any pressure, so should be fine. Picture is from my 302 air cleaner, but you can see the black fitting where the flexible hose attaches........
The AC should switch to coming out the DEFROST when accelerating. Very common and NOT an issue. Just the way it is. All my Maverick AC cars do this.
I would like to thank everyone for their input. I flushed the radiator three times, last time I left the cleaner and distilled water in for a week and drove it back and forth to work every day. Heater on in the morning (with windows down) and A/C on in the afternoon. After 5 days I drained it refilled with antifreeze and have not had any issues.
Glad to hear...
I doubt they were that way from new(time to break out the shop manual), I don't remember my '75 Granada having that issue.
Easy enough to install a one way vacuum valve, if it still switches, there's a leak(yeah, probably in selector).
Does anyone happen to have a PDF of the FSM/TSM for the 77 Maverick the could e-mail me?
