a/c stop working
 
help, during my trip from quebec, canada to myrthle beach, the a/c stop working and never want to freeze again. So the a/c are not working. Just before the a/c die I heard a hissing sound. (like if the compressor bearing of fan bearing went bad). I'm not able to have a appointment to the ford stealer before 3 days and I want to use my truck in the hot weather that we have. I forget my owner manual and I don't know witch fuse can be blown or were to look at. Please if someone have the fuse display (witch one do what). Or if you have a idea of what my problem is, let me know

Hi pasprobe, welcome to FTE!

What year Expy do you have?

EDIT: profile shows 2007

On my 2005 SD, the solenoid value was bad. "Got a call back from Service today, TSB 05-14-4 is what he stated they looked at to fix the problem.

Going to replace the vacuum pump, part no. 6C3z-2A451-BA. Cost to repair $345.00."

This may be your problem or it could also be a vacuum leak in the system.

This is a picture of what it looks like.

Sounds like you have a leak in the auto-hub system. Start at vac lines to hubs, replace hose as necessary. Then follow those lines to pass-side fender well (engine compartment). There is a solenoid valve for hubs near vac pump.

I doubt your hubs actually locked in 4wd. If you can spin the front driveshaft or either axleshaft w/trans in neutral - hubs not locked. You can also jack one front wheel at a time and if tire spins while in 4wd - not locked...

After verifying vac IS going to hubs, check hubs following these directions:

This may help you some.

It's a expedition 2007 limited max or EL in us word

I finally find the owner's manual and check every fuses, they are all good, I also swap the a/c relay without succes, so something is telling to not start the compressor, maybe the valve you are talking about or does it have a safety pressure valve. Maybe after 24 hours of driving in hot temperature the pressure went to high?

Just curious, do you have A/C from the defroster vents by the windshield?

no, nothing, the compressor doesn't start at all, the relay click but the compressor do nothing, I'm able to turn the compressor by hand but the clutch look like dead.
