The A/C stopped working not long after I got the Excursion. 95% of its life was in an environment where A/C is not really needed so I didn't fool with it for a couple years. Last summer, I decided to take the X on a roadtrip and payed a local mechanic to change the condenser (had an obvious hole in it). I had him change the orifice tube under hood with the 'cold air' orifice tube while he was in there. So, A/C is keeping inside of X about 60* on a 100* day andmy kids have the nerve to complain they are cold!! I just tell them to remember these things and tell their therapists later in life... but I digress.

About 3/4 of a day of driving thru the literally 100* heat - the cold starts to fade and pretty quickly went away. DAMMIT!

So, there ended up being copious amounts of compressor oil all around the connection from line-set to condenser and I planned to go shove it up my mechanics... then I ended up just parking X until it was cool out and kinda fergot about it. (the X won't pull my 5ver is why it was parked...)

Fast forward to the beginning of summer here in OK. I will push this thing off a cliff before I live in this climate with no A/C, so I brought gauges and vac pump with me!! Last nite, I remove lines from condenser and was hoping to find wrong-size/torn/improperly installed/SOMETHING not right about the o-rings - NOTHING. I replaced them anyway (with same size) and reinstalled after lubing with PAG oil. It will not hold a vacuum........

I thought I could hear it leaking near those orings, but my hearing SUCKS - so I cannot be sure. I can't really see anything wrong like a crack in the line(s) or condenser itself - but I kinda think thats where the problem is.

The long, boring story was to ask what the SPECS are for those o-rings and is there something I'm missing or not doing right? Meanwhile, anybody have a spare set of wheels WITH A/C I can borrow until we sort this out???
