After playing around with the controls this is what I found. I too had the "low on freon" smell. So I tryed this and it seems to work so far......
Turn on MAX on A/C and the temp setting should be set to "LO" >>> DONT TOUCH THAT DIAL >>> Leave setting at "LO"... and KEEP IT THERE !!!
Don't set any other tempteture other than "LO"....
If cabin gets too cold, adjust the "FAN" speed ONLY..... not the tempature setting....
If still too cold switch to "recirclation" setting..... Again >>> leaving the tempature setting at "LO" [always]
I live in Las Vegas and this is working so far for me..... Hope this helps some of you.....
