Rear air stopped working

[scotto0609]

So my 99 suburban ate the a/c clutch earlier in summer. A/c still worked but sounded like garbage. Anyway i changed out the compressor accumalator and orfice tube and had the a/c recharged the front a/c work but now the rear just blows air. Any ideas of what i might have done wrong. thanks

Does the rear air temperature change from cool to warm when the temperature dial is adjusted?

Does water (condensate) drip from the rear with the a/c on? I'm not sure where the drain is on the 92-99, but on the next generation it is a rubber flap going through the floor roughly above the exhaust pipe. If you find it, pinch it or run a pipe cleaner up and see if water comes out.

If condensate is coming out, then you'll know that the rear evaporator coil is seeing flow and it may be an issue with the temperature blend door.





Otherwise, you may have a clog or pinch in the lines going to the back. Mmaybe take a look and see if any are obviously damaged. I doubt you have a leak in them, though. A shop may be able to flush them, I'm not sure.
