I put a new alternator on my '03 F250 6.0 yesterday. Today the A/C will not blow out of the dash, it blowing out of the defroster. I'm assuming I disconnected a vacuum hose? I've looked everywhere I can think of. Any ideas?? Thanks
on my 2000 the vacuum pump wasnt running and was causing this issue, i tore the pump apart and found that the pressure switch inside was sticking and not letting it run. doubt this will be the same for you but never know
Assuming you have AutoHubs (4x4), do they work correwctly or do you have to get out and manually lock them? I had a similar issue and it turned out to be a vacuum line goingg to one of the hubs. And IIRC, the vacuum pump on a 6.0 is electronic. I thought it was mechanical on the 7.3. (Not familiar with it)
