SOLVED: 2010 Tahoe LTZ Pulled dash for core R&R, but can't figure out 1 remaining cable

[jared999]

Took me 4 hours to get everything out and 3 to put it back together. I'm not including the time spent fixing my cracked dash or locating the mystery plug connection.
I could have gotten the dash out quicker except I took extra time labeling bags and putting screws and bolts in there for reassembly. =

Honestly, with the correct tools and parts in hand, this is not a difficult job. It's all about having the right tools and parts though. I am going to post a video on youtube describing what to do with the HVAC box and what the actuators are, because I could not find a good one for Tahoes and Yukons. Most of the ones on YT are for silverados and such and the actuators and hvac boxes are different.

How much did the parts set you back?

 

[jared999]

GM Evap Core 160 .00
GM Heater Core 115.00
GM Inlet Hose T connection 22.00
GM Hose T connection 22.00
GM Heater Inlet Hose 22.00
GM Drier 32.00
GM Actuator 30-35.00
GM Actuator #2 30-35.00
Continental Tank to Core hose assembly 32.00
1 Gallon coolant (I already had. didn't need entire gallon).
Shop towels (already had)

So about $460 shipped to my door (those prices include tax/shipping).
Rock auto for most of those parts, amazon for one of the T connections.

The videos I saw of the R&R for the heater hoses made it look quite difficult. I decided I was just going to cut those T connections and replace them with new ones, vs. fiddling with getting them off and so forth. Best $44 I ever spent.
My heater hoses were bad so I was already committed to replacing them.

I should add - I replaced a known bad actuator (driver blend door) and a good actuator (mode actuator) but left the other two good working ones.
Reason being the mode is a ***** to get to. The two actuators on top, if they ever go bad are easy to replace so I left them.

Great info, look forward to your video.

Is doing a job like this something you are having to do soon?

Hopefully not but I love to learn about it just in case **** hits the fan. I got a lot of miles on her.

Got it. So the best video I have seen so far is this one:

Very similar to what we do for our Tahoes. Only real difference I found was we have 2 T connections (at least I do for my options) under the hood and my heater box was plastic welded and metal screws in other locations. I ended up drilling those wells with a 5/16" bit and then putting bolts in there after I was done to help seal it back.
The hardest thing to do is the get to the nut behind the engine. It's a PITA.
