He says he checked the fuses and all were OK. He's 62 and still single, so no wife to fan him. The fact that he can stand to run beans on a HOT dusty day with the cab door open , well there's a reason he's single! HA! 

Back when I ran my 1st combine, a '76 IH 715 with only a fan was enuf for me! The next 715 had AC and was at least tolerable. I've always made sure I have a working AC in the combines I run .I can't  tolerate a dusty dirty cab!
