Thanks for the information. I was afraid that might be the case. I'm glad that at least my system is set up and functioning correctly, albeit not as cold as I would like it.

I'll look into the 80/20 air to 100% air mixture setup. I've heard that the W126 functioned that way, and I vaguely remember reading somewhere that people have tweaked their systems to be 100% recirculated air during A/C or specific vent settings. I'll keep you posted.

Thanks again for your help. Now, perhaps it's time for some good window tint...
