"defrostin" When 4-wheeling
Last weekend I was out climbing some rock trails in the desert in my 05 6.0. Sound pretty typical for a weekend. I have the electronic switch for 4h and 4L with manual locking hubs. When the A/C is on and i switch to 4WD the A/C goes into defrost mode and it was hot
outside. the A/C will only come out the defrost when its in 4WD. Is there a vacume leak somewhere or does that extra defrost air help to keep all 4 tires on the ground. Has anyone had this problem. Any feedback would be helpful.
