Well after last years naracoorte 4x4 challenge my sierra's heater was full of mud.
And since then everytime you put the fan on it would blow out dry mud, the heater didnt work and the controls were all jammed up.
And the air vents were jammed open blowing cool air.
So with all the lovely warm weather weve had lately here in south oz , i got motivated.
I had read about the heater refresh on izook and thought that looks like a bastard to do, and i didnt want to pull the dash out.
So i read this

And gave this a go, i drilled the hole which chunked a bit because the plastic was so brittle.
I loosened up some of the leaves and mud that had welded them to the heater core with an old tooth brush and then fabbed up a nozzle to the vacuum to suck it all out.
Then i got out my compressor with a blower attachment and gave it a good blow out, then one more vacuum.
Next was trying to free up the controls and flaps in the heater box.
I used the old rp7 with the squirt nozzle and sprayed in behind the dash to hit the linkages, and i sprayed every pivot point and moving part i could find on the heater box.
After that they slowly free'd up and now my heater works.
Yee haw
I patched up the hole with a piece of icecream container, araldited on then siliconed up. i didnt worry about the washer toggle way on izook.
