I believe that a separate recovery/recharge machine is required by regulation for each refrigerant type. Now for service gauges, I have R-12 gauge set, and actually purchased adapter fittings for that and used mine for both R-12 and for R134a. I later bought a set of R-134a gauges. And of course I u...

ok, i know this is going to sound crazy, and I'll probably get scolded for it, but I'll ask anyway... Anyway, this size can would be perfect for me to use to do the A/C on my truck (22oz), and it would avoid me having to deal with using two 12oz cans & having to purge the lines when swapping, k...

Yesterday, I was there with the truck and took a look at this with my UV light and yellow goggles. I checked the entire system, including compressor fittings, front compressor seal, condenser, drier, connections at the firewall, even the condensate drain hose, did not see ANY dye/leaks. Maybe the n...

The parts store said there was a recall on these vehicles due to refrigerant slugging. The fix was programming the system to cycle on and off when it first starts up. I had the "slugging" issue on our 2005 Yukon Denali with rear AC, kept breaking the AC belt but still cooled great until t...

Thanks, I have an inexpensive electronic leak detector at home. Will try that on air vents and condensate line later this month. Maybe the new valve caps sealed the leak.

OK, I bought this 1998 Frontier back in 2004 with 100K miles on it for my kids to learn to drive, and they both drove it through college then unexpectedly returned it to me. The AC has worked well in it since that 2017 pinhole in the high side line rubber part detailed in initial post in this threa...

Yes, R-12 is relatively expensive, even though it is plentiful as demand has been slow as older vehicles go off the roads.

Yes, R-12 is available to purchase.

I agree the easiest and maybe least expensive route is to stay R-12. My own 1988 Mazda truck is still R-12 (Arizona).

Don't give up just yet. It might be something relatively simple. Check the clutch gap next. If it's too wide, the clutch won't engage and hence, no cooling. That's what Cusser alluded to when suggesting that you tap on the front of the clutch. Sometimes, that's enough for it to engage. Whether you ...

I never saw the compressor clutch engage so I suspect bad compressor. Wow - I'm not an AC professional, and first thing I would've done was check to see if the compressor was engaging. I wish you had done that on yours as initial step. I actually encountered this VERY SAME situation yesterday in my...
