Hi, guys! I haven't been here in a few years, thanks to good luck with AC systems. Great to see an improved, spam-free forum.
I bought a 2005 Grand Marquis two years ago with 80K from a nice old man who had to give up driving. AFAIK this car has never been serviced aside from battery and tires. It's a New Mexco/Arizona car now living in Salt Lake City. It's at 106K now.
This summer we hit records (100F) daily and I noticed very slow cooling on my afternoon commute home. The car has to sit outside all day, unfortunately, so the inside temp gets over 120F..
I started monitoring the vent temps on the way home, and noticed wild swings from 70 to 55. On the 10-mile drive, this barely improved.
I thought perhaps after 13 years, enough R-134 had seeped out to require a little recharge. I opened a 12 oz. can (pure 134) and the high side went from 200 to 250 max during the charging. I forgot what the low side did, but it seemed normal.
This fixed the problem with the vent temps, dropping to as low as 36F within a mile of starting the drive home.
Then I noticed a yellow stain on the driveway just below what looks like the dryer. Uh-oh. Vent temps started rising again, and now they're worse than before I tinkered with it.
Go ahead and lecture me about adding gas blindly to a system. My question now is, what can I do to fix this? There's a little yellow oil on the bottom of the dryer, but the hoses on top have nothing on them. It's as if the dryer itself is leaking from the bottom. I'm not familiar with this type of dryer at all.
