07 Expedition Air Cond

[Matt In Detroit]

Hopefully someone can help. I have this 07 Expy, the dealer has recharged the A/C twice, both times it has lost the charge. They did put dye in and say they cant find any leaks. Obviously it has one. Anyone/techs have any ideas on a possible leak location? something to check? Id take it to another dealer but this has been an issue since i bought it so they have been working on it for free. I looked it over with a black light and saw no dye either. Some tricky area prone to Expys? thanks for any help Matt

check the rear condenser. not sure where it is on these, but with all of those lines, you very well might have a leak way out in the rear-end of the vehicle instead of up front by the compressor

Thanks for the input. Last night i did a real good look in a dark garage using a black light, fine tooth combed it. I found dye up front by the radiator on the drivers side. I also found a little bit of dye at the connectors near the rear unit behind the trim panel. Good call Tylus. So at least i have a few places for the dealer to check out.

Thanks.

They should be able to fix it with that information.

glad it helped somewhat.

I find it weird they didn't find that themselves. those rear units are known problems on all vehicles...especially as they age. would have been the 2nd place I would have looked, and I'm only a shadetree mechanic.

You know, doesnt surprise me much. Im an old school carburetor and points kind of guy, even though im only 41, and i find most of the time my extensive hands on experience and common sense approach sometimes beats a younger and supposedly better educated tech. My dad told me once. before you grab a wrench, look at everything real good, you will find your issue 50% of the time. Got to say he has usually been right.
