Mark's shop worked up an estimate on my '84 shortly after I bought it
in April. I found him very nice to work with.
My A/C wasn't getting cold. Mark said he found a major leak in the
compressor. He said he couldn't effectively test the rest of the
system until the compressor was replaced. Fair enough.
The estimate was more than I wanted to spend (and I didn't have time
to do the R&R myself, as Michael wisely did), so I put it off.
In May, I took my camper to GoWesty to have the new
higher-compression engine put in along with a lot of other
work. They wanted to fill up the A/C and pressure test it. I
resisted at first, on the strength of Mark's report.
In the end, I told GoWesty to go ahead. They charged up the system
with their preferred gas (I've forgotten the details) and said it
pressure-tested fine.
Now, I'm pretty sure Mark in San Carlos DID find a leak in the
compressor, but it is surprising that the compressor now works
well. Maybe GoWesty uses a sealant or seal conditioner? I don't
know. Mark seemed very competent and honest, so I doubt he was wrong
about the leak.
I ran the A/C for about 2,000 miles, and it worked fine except for
two complaints unrelated to leaks:
- Condensation dripped on my luggage after an hour or so.
- The engine tends to stall at stop signs when the compressor is running.
- The compressor whines pretty loudly.
I returned to GoWesty in June. To address the dripping, they
replaced a broken condensation catch tray with a good used one. I
didn't ask them to look into the stalling. (Don't remember why.)
On the whine, GoWesty recommended running the compressor until it
fails, since it's an expensive item.
I used the A/C rarely over the summer, if you can believe it. I just
didn't need it in June, when I drove to New York, and then I didn't
drive much for a couple of months.
I needed the A/C badly when I left New York this week. I fired it
up, and it worked great. But after a couple of hours, it started
dripping again. So I switched it off.
At Westy Ventures a few days ago, we found the drain hose was running
"uphill" from the catch tray, so we tied it down with a couple of
clamps. It now runs level with the bottom of the cabinet all the way
to the closet.
I fired up the A/C on the next long leg, and it still
drips. However, whereas before it dripped pretty much all around,
including at the front where the new clamps are, this time I saw a
drip only at the rear left corner. (Are there drain hoses at the back, too?)
I haven't had time to look into it further. I'd welcome any
troubleshooting tips for the dripping, and brainstorming on the rest
of the issues.
