A/C question

[89Suburban]

With a set of manifolds and a vacuum pump from Harbor Freight, you can do this repair yourself. Also had to buy an adapter to better puncture the cans to add refrigerant from Amazon or O'Reilly Auto.

I just bought a set of their gauges and I am having issues with the adaptor I bought and what seems to be a resealable can of refrigerant. Works like crap. Not sure if I got the wrong adaptor or what. The gauge kit is nice, got it on clearance.

That's the one I bought above, even then we've had several dud cans and were able to return them for exchange at O'Reilly's.

Heard that the rear units are problematic. Have an '02 Suburban with rear a/c and lot of trouble tracing down the leak. Not sure if it actually was the rear.

Don't use any stop leak - it gums up everthing. Had to get new compressor, dryer & condenser and orifice tube, seals, o-rings, etc. Amazon sells a rear block-off adapter for $20 which works well. I now have a good working front A/C. Don't over look the schraeder valves or the other sensors, as well as the PAG oil & dye.

I went all new parts, because of the stop leak, and to avoid going into this issue 2 or 3x.

Don't have rear a/c, but at this point front air is better than no air (Houston, TX).

Amen to that one! I live in Dallas and the heat has been oppressive. I can only imagine how much worse it has to be in the land of heat and humidity.

I'm actually curious where exactly leak turns up on the rear evap. The inlet, outlet, in the heat exchanger portion, on the fittings?

I have both cores leaking and am looking at $2K plus to replace both. Am going to do the heater core while they’re in there so won’t have to go back in there for the rest of the trucks life (fingers crossed). It’s an 06 with 200k miles.
The dye is all over my front vents and in the rear, it’s is all over the slits in the rear panel on the right. Go out at night with a UV light and looks like predator got killed in there.

If you are savvy with taking photos, consider doing a tutorial of sorts.

The rear is REALLY easy to get at. Might be worth considering doing it yourself. I redid my rear... I've also tore apart the front. The front is more involved. Many people cut the dash to do it. I'd not do that. I'd do it right and take out the dash itself. That said the front isn't impossible just a lot more fasteners and stuff to get out of the way. I've taken apart a few of these dashes now... go to the junk yard and take one apart for practice then take yours apart. That said it maybe worth it even at $1200 to have a shop do the front. Especially if they'll warranty / stand behind the work.

Dye in Front vents and the rear panel as well as carpet at the bottom of the panel.
