00 WJ Heat issues

So it finally got cold enough here that I turned the heat on full blast. There really isnt any heat at full fan speed. If I turn the fan speed down, then I get some heat. 2000 GC limited, 4.7 Quadra, AZC.

The PO had the green coolant put in at some point, so I need to get that cleaned out. Here's what I am thinking. Take the beast in and get a good flush, pressure test, thermostat change, and the proper coolant put in. I am also going to get an oil change since I have only had the Jeep 2 months and god knows when the PO had that done last. Anything I am missing or other stuff that I should check?

Could be clogged so a good flush might help you out. the heater core might need to be flashed separately.

Turns out its an AZC door issue. Heat is better after the flush, but only on thedriver side. The diag gives me a code 56. Gonna have to research that now.
