    I've read up on the project. I've got the whole weekend scheduled for this. Can someone please send me a link to the "blend door actuator, heater blower resistor & evap core"? I'd prefer to buy them off Ebay because it's cheaper.

    Looked it up. I don't think I need to replace the heater blower resistor. I'm definitely swapping the evap core.

    Just remember the cheap crap on ebay you may get what you pay for and have to do this again next winter. The cores are just little radiators but the actuator you may want to get a name brand on that.

    Got my heatercore from the parts store today. Also ordered a evap core, should be in in 2 days. As for the door blend acutator; there seems to be 2-3 of them. Can anyone confirm? I really don't want to drop $200 for them if the one's on there still work.

    AC purged. Can someone tell me who to swap my evap core? Co-worker says it's in front of my radiator. I thought it was next to my heatercore behind dash.

    I would not replace the ac evap. this is seldom a problem in most all vehicles. this is in the air box near the heater core. the ac condenser is in front of the radiator. the evap coils absorb heat from the interior. the condenser releases the heat absorbed by the evap coils.

    just replace the heatercore and the temp door actuators/stepper motors. clean the box up of any dirt wash the coils.

    Can you shed some light on how many door actuators I got? I can visually see the one in the center/bottom dash behind the sound insulation.

    I have seen alot of evap cores go but im in the rustbelt so depends on where you are, the number of motors depend on if you have 1or 2 zones (pass independant temp controls, so 2 temp knobs). I pretty sure you only have one and it should be on the seat side of the heater box towards the center of the dash. These are common fail for our trucks and mine is bad aswell but still mostly wirks so i havent bothered with it.

    Just noticed your in southern ca, i would def replace the evap with the use it gets out there. Also is everybody really complaining about the 60 degree wheather out there? Its 10 here, if it was 60 id go swimming.

    Watched a bunch of youtube vidz. I'm probably going to take apart the acutator and clean it out. I'm pretty excited about the project. I've got everything I need to get the job done.

    I think cleaning off all my vents and tubing will consume most of my time. Everything is super dusty and I want to wipe everything down.

    I wonder what my cabin air filter looks like?

    Half way thru this project. Wife went all crazy when she saw the truck. It was hilarious!!!

    There is dirt or sand everywhere behind the dash. I'm taking my sweet ass time and wiping down everything with antibacterial wipes. OCD? Possibly.

    Broke 1 vent tab. Stripped the bolt for the AC evap core. Might run down to dealer for it.

    +1 on leak testing, looks good so far.
