yes both heater hoses get hot so when I put it on AC it stays on vent so that would be the blend door

Dude you feel the heater hoses under the hood to make sure they're both hot? Default when there are vacuum problems is usually to blow warm air out the defrost. So cold air indicates its either not getting heat inside or probably a blend door isn't working properly.

This is likley not a blend door issue. When I think Blend door I think of temperature control. It could be vacuum lines underhood or under dash that have gotten brittle and failed as others have said, but I doubt it. The Vacuum servo has likely failed internally. This has happened 2x on my F...

Sounds like your blend door actuator might be stuck or the vacuum lines are shot - those old Mopars are notorious for vacuum leaks that mess with the HVAC controls.

Not fully sure how that one works. If it's the same as the Chrysler one it's semi automatic with a sensor an motorized blend door that can fail and cause issues. And the vacuum lines behind the controls can get brittle and break but doesn't seem to be as much of an issue in places like NY. I...

Looks to be vacuum-operated. I think so. it's a monster compared to what's going to replace it.

Is the blend door on that car operated by a servo or vacuum? Mine stopped working because the electrical connector lost tension on pins for the servo control board. I scuffed the pins a little and added solder to build them up. Been fine for 12 years now.

What stopped working? Blend door actuator?

...look like the valve is good, but not sure if there actually is vacuum there. I haven't had much time to work on it, but I did see that the blend door is on the other side of the control unit, and I am going to try to wire it closed to see if that will do the trick If it does, then I am going...

justanswer.com/chrysler/7aoz7-1985-chrysler-fifth-avenue-cold-hot-control.html If you scroll down, you'll see what they are calling the blend door motor but I don't recognize it. It's been years since I looked at mine and maybe I don't have a good memory of it. It does show a means to test to...

Wow, thanks for the diagram. Nope, I didn't have the blend door connected to the coat hanger. I will take a look at the location above number 2, and let you know how I make out. Thanks again!

allpar.com/threads/blend-door-servo-wanted-89-5th-ave.240650/ See part #9? that post on the back of it pokes up thru part #2, and the servo will be ontop of it

yep, it's tucked down in there but it looks like it was just barely designed to be accessed down in there. Check the electrical connector first, they can get loose I have heard

I just saw your previous post, and yeah, maybe that wasn't the blend door I connected to. So the servo is inside the car, and I should be able to see it on the left after I remove the glove box?

...is in Max Cool. So if your interior is warm, that will only keep the cooler outside air from coming in if it's open to the interior. The blend door problem is over on the other side of the heater box near the center of the firewall. It's a servo motor that sits ontop of the housing. Remove...

...in WI, you'll soon need the heat. I have an idea that if you remove the electric servo motor from the top of the heater housing, the blend door will rest in a default position of supplying heat. Instead of replacing the servo if you can find one, and if you don't want to mount a cable unit...

I am sending a few pics showing that I closed the valve on the heater core hose, and that I do have a clothes hanger hooked up to open and close the door. Like I say, even with the door closed, the heat comes through. Thanks for hanging in there with me on this.

...in the heat coming out the vent? You've checked to see the the prior owner already installed a manual line/switch/lever to control the blend door? I ask because we did that with an old truck and when mom drove it going to town for sandwiches, she came back sweating and cursing the heat in...

I did remove the glove box and found the blend door. I wired it closed to make sure that took care of the problem, but the heat is still coming through. Could there be another door that is in that area, and I closed the wrong one? I also closed the valve in the hose to the heater core and that...

I will be back in town next weekend and will try to access the blend door then, and I appreciate the closing ideas for opening and closing it. Tom

Read thru these very helpful messages regarding "blend door". Search results for query: blend door Your 1982 Cordoba is equipped with the "semi-automatic air conditioning" system. Really, the only thing automatic about these is that the blend door has an electric motor which opens or closes...

If it's not the controls or the vacuum lines going to the controls it could be a stuck blend door causing it. On 5th avenues it's electric. I don't know if it is or not on the other cars. Even with the valve under the hood open the heater box should still stop the heat. The valve is usually out...

...parts that ALMOST fit, etc. You shouldn't need to modify s part so it can be put on. Those are all reasons I waited 3 months for a Ford blend door actuator for my Mustang. Could have had a Dorman one right away but, I don't want to do the job again a month later. Ford one made in USA, Dorman...

I have heat! Removed the dash cover, glove box and passenger side vent ducting then adjusted the blend door into the full hot position. I then put a socket between the bracket and rod on the recirc valve in the engine bay so it's stuck open. Its cookin' hot in there now! Thanks for all the help...

The blend door stopped working on my 5A shortly after replacing the heater core. The plug actually failed to make a proper connection as there was no tension left in the plug itself. You can test this by playing around with the plug and running the temp slider from side to side. That door...
