I'm missing parts on my heater box but the ones I find with ac are different than mine. The part is where the fresh air attaches to the heater box on the passenger side. My heater core is on the left looking at it under the hood. All I'm seeing is where the blower motor is on the left under the hood. Any help would be greatly appreciated. Thank you

 

If you're just seeing the heater motor protruding into the engine bay, you have a dealer added AC. Dealerships didn't use the factory installation .... I think because it requires a hole in the firewall might near big enough to crawl through .... before supper.



The whole lip fits through the hole



Factory installed AC

I do not have a picture of the actual hole, but this fellow filled his with a piece of old sign.



I cut my hole long ago, before digital cameras even.

 

Do you have a heater only? If you have heater only, you should only have the end of the blower motor sticking thru the fire wall and the 2 heater core line nipples.


If you have the large box pictured in the earlier posts then you have a OEM a/c-heater. If not post a pic of what you have to help up figure out what you have.

 

Wow! If you have dealer added AC, I would love to see pics! Those are pretty rare if I am not mistaken, never seen one...

 

Rich did a great job at describing factory AC, as always! If you don't have dealer air and have factory, here are some more pics, as I just tok my box out to service the blower motor and heater core. I will also attached some useful videos I watched to help me. If you see any parts missing in the videos or pics, tell us the time stamp you see them at or circle it in my pics and we can figure out what all you are missing.



Dealer A/C box in the engine bay

After removing cover on inside of the cab (passenger side under glove box). Evaporator is the first thing you will see

De icing switch and other wiring to the left of evaporator

After removing the plate the switches are on and the evaporator, the heater core is exposed and the blend door as well.

Blend door, inside that is the blower motor which will have the cage on it

The box out of the truck

If your a/c dash looks like this one then you have the dealer installed a/c. Note the 2 ***** under the double vent.

If your dash looks like this one then you have the factory installed a/c and you should have the large plastic a/c box under the hood. The dealer installed a/c doesn;t have that large box under the hood. Just the typical standard heater blower motor under the hood.

Here's a view of the factory installed a/c with the dash removed.

 

OEM a/c

HAD OEM a/c, but now has what I believe is aftermarket a/c. Vintage or Classic Air?

Heater and fresh air only NONE a/c.

Another heater and fresh air only.

 

Are factory ac boxes a desirable find? My parts truck has what appears to be an intact setup, if they're desirable I'll pull it. If not, I'll send it on it's way.

 

Not particularly. They are bulky to ship. An entire setup may be worth a couple hundred in parts together. Not really an item worth retrofitting as they take up a lot of room under hood and require a large hole to be cut. It has been done but ac trucks aren't rare.

 

I ran across a vendor a couple of years ago at the Carlisle Ford Nats. that had a complete factory installed A/C system in a box. He wanted crazy $$$. He was asking $1500 for the set up and the condenser looked like it needed to be replaced. Needless to say I kept walking right on past.
