4 Season AC vs All Season AC

Any difference? I know from the assembly manual that there are about 5 different "levels" of HVAC in the various types and options, but my SPID says "All Season" while most others I've seen say 4 Season.

There are only 4 seasons, so it sounds the same, but...

Re: 4 Season AC vs All Season AC

Depends on who was "manning" (or womaning?) the typewriter that day?

Stuff also varied from plant to plant. Some plants marked stuff certain ways, while others did nothing at all.

Re: 4 Season AC vs All Season AC

RPO C60 is the full feature system that blends heating and cooling with both fresh air and recirculation options, making it usable in all/four seasons.

If it makes you feel any better every 70 Fremont truck SPID (Chevy and GMC) I have with C60 is described as AIR COND-ALL WEATHER.

Some of the other systems are recirculation only like the underdash, rooftop or rear on a Suburban.

Re: 4 Season AC vs All Season AC

Ah. What would make a non-fresh-air unit not work in a particular season, and what season? Winter? Would it fog the windows or what would be bad?
