2003 tahoe heater core, evaporator, blend doors, actuators

[ncalvo]

I am looking to pull my dashboard to replace the heater core and evaporator and want to replace anything else that makes sense while I am in there..
I have cj2 code, dual zone auto digital climate controls up front

I'll be replacing the dryer/accumulator, orifice tube since the ac system will be opened up

how many actuators there, which ones can you only access with the dash out?
I know I want to replace the mode actuator under the dash driver side because it has made a squeaking noise for years

I am looking at these parts lists and just trying to identify how many of each part there is

There are 4 actuators up front and you should be able to access them all without putting the dash in the service position when replacing the heater core. However, you can easily get at the passenger side temperature actuator and the fresh air actuator while making that repair. Use GM OE parts so you won't have to replace them again.

If you want to be fancy, swap out your dash with an Escalade dash, and add cabin filters to your mix.

Do all the GMT800 SUVs have the filter? I thought they didn't -- just the Escalade.
