The Weather Eye was a trade name for a Nash Motors-designed fresh-air system for automobile passenger compartment heating, cooling, and ventilating.
[2] The use of the Weather Eye name for automobile passenger heating and air conditioning systems continued in American Motors Corporation (AMC) vehicles.
In 1954, Nash-Kelvinator capitalized on its experience in refrigeration to introduce the automobile industry's first compact and affordable single-unit heating and air conditioning system optional for all Nash Ambassador, Statesman, and Rambler models.
[16] This "first true refrigerated air conditioner system" for automobiles was also compact and easily serviceable with all of its components installed under the hood or in the cowl area.
[17] Entirely incorporated within the engine bay, the combined heating and cooling system had cold air for passengers to enter through dash-mounted vents.
[18] The optional air conditioning system offered by Oldsmobile cost $199 more, and it weighed twice as much as the integrated Nash unit that added only 133 pounds (60 kg).
First as optional equipment and later as a standard feature, the Weather Eye system was continued by AMC after the merger of Nash-Kelvinator Corporation and Hudson Motor Car Company in 1954.
[24] Effective advertising positioned the AMC Ambassador against the Chevrolet Impala and Ford Galaxie as an unfair comparison because neither of these direct competitors included air conditioning as standard.
