    2005 AC Pressure Switches

    Do you have to evacuate the system to replace the ac pressure switches on a 2005 with a 5.4 or do they have schrader valves?

    Intermittent AC clutch

    I just realized you said fan clutch. I was thinking compressor clutch. Yes, I have replaced the fan clutch because it wouldn’t cool unless I was moving and that took care of the problem.

    Is there a way to test the clutch? I did the tap test to make sure it wasn’t a gap issue but it wouldn’t kick in. It’s working fine right now but you never know when it will quit and for how long. Is the clutch easy to replace? I’m not really wanting to just replace parts but it may be worth it...

    Rear End Noise when starting off cold

    I am getting a vibration and rumbling noise in the rear end of my 2005 Expedition when starting off cold and turning. I found TSB 04-24-20 on line. Has anyone had any experience with this?
