I am going to take a moment and put this down on paper, as most times when a repair is made - follow up is non-existent and would be advantageous to other users if we all took a little time to post follow up, so here goes:
EQUIPMENT:
2005 GMC Yukon XL SLT 4WD VIN "Z" 5.3L 189,550 MI / Automatic HVAC Controls - Dual Air/Heat
CONDITION:
AC was cold, then slightly warm out of all vents and not keeping up as the rear AC was ice cold, could not hear sound change when going back & forth between RECIRCULATE/MAX AIR - sounds like an actuator not working [Blend Door]
1. Tried to pull codes with my old scanner and knew that it would not work on this issue but tried anywho, as been looking at new scanners for all the new vehicles [2018/19] in family just hadn't decided on which one yet [what about da' ole man getting a NEW truck as everybody else is???],
2. Order new OBDII scanner, went with Blue Driver as always have an iPad or iPhone with me & liked no cables [Bluetooth],
3. Had my AC gauges in hand, then left on work bench before road trip [first mistake],
4. Now out-of-town, scanner arrives where I am located as I planned ahead, pulls B0229 code, Recirculate Position Feedback Circuit Range/Performance, which is a common code in this vehicle:
REPORTED FIXES:
a. Replace Blend Door Actuator (BDA),
b. Replace Driver's Temperature Blend Door Actuator,
c. Replace Recirculation Door Actuator,
NOTE: Ordered Dorman 604-106 Recirculation Door Actuator [OEM GM 52405288 superseded by GM 89018365], as vehicle has driver side [bottom side], passenger side [top side] and recirculate [topside-behind air bag/glove box area].
5. Replaced actuator & reset/recalibrate all actuators as per OEM GM Manual and road tested and it was cooler but not perfect as vent temperature was not what I wanted and/or what I was used too,
6. Let's hook up AC gauges, not happening as a 150 miles away on workbench [see #3] and was my 100th WTF moment that week,
7. So do I buy new gauges or wait, with temps already in mid-high 90's, and forecast of record highs and my elderly dog to transport around, it's not happening, so I went to Wally World,
8. Got big can of R134a with gauge, hooked up gauge said ok as it read @ 30-32 lbs and anybody knows with ambient temp what is was it should be higher, popped some freon to it, while on "MAX AIR" & 60 degree on display and got it cooling,
9. So must have a small leak, will monitor and carry gauges for awhile.
So in closing, first mistake was not bringing gauges but was able to accomplish it/repair & solution using inexpensive can/gauge combo from Wally World to get going while out of town and would have been my first CHECK on vehicle had I had them.
So CHECK PRESSURES FIRST!!!
As REAR HVAC will blow cold and seem fine all the while it is blowing warm or hot air out both [DVR/PASS] front vents.
