Yeah what's most likely going to be your problem is 2 small pinkish/purple vacuum line and a gray vacuum line that hooks up to your heater core valve up under your hood on the passenger side all you have to do is reconnect that to the vacuum ball and connect the vacuum ball to a manifold vacuum on top of the intake and you would have had your blend doors working again. Vacuum hose diagram is on your fan shroud up under your hood and on the internet for your particular car will show you how to hook back up everything

[@CutlassVibes]

I couldn't find where those 2 vacuum lines go exactly online do you know where I can find that info?

[@CarReviewsbyKJ]

I’m going to try this. Having the same issue with my 442

[@OTCLLC]

Okay good deal let me know how it works out for you....

[@nogarage4473]

I am going to try this. I got a problem with the 81' Malibu only blowing from the top vents. I'll update once it's done.

[@OTCLLC]

Alrighty Boss sounds good let me know if it helps you out!

[@nogarage4473]

Didn't work. . I sprayed on some Penetrating Lube I had on hand it didn't move. I checked all the Vacuum lines and they are all Stat. I am going to assume I will have to replace the Climate Control.

[@OTCLLC]

@@nogarage4473 Sorry it didn't work out man maybe that climate control unit is shot sometimes before I spend money I'll check local savage yard and see can I luck up on a couple good one's

[@nogarage4473]

@@OTCLLC Will do. Thanks

[@onetime5547]

Any way you can do video on the vacuum lines, under the hood purple and grey lines. My cutlass vacuum lines not connected need to find out we’re to hook them up to.

[@OTCLLC]

Oh Yes i will put one up explaining where to hook them up be on the lookout for it sometime this week..

[@jaycee6639]

Did you find out I'm in same boat

[@hielw-yu1uc]

good

[@RyanGuy-mn7wf]

What up. For 83 Buick regal I have to take the whole dash off or is there a way I can get to the vent without

[@OTCLLC]

Um let me look up some regal dashes and I’m going to get right back to you my brother has one I’ll let you know in a day or so but it should be easy

[@geraldalvarez2503]

I bought a 86 monte i am replacing Pivot point Temp Blend , i want to know if there is part that is stable on car to clamp on to the door

[@OTCLLC]

Hey I'm going to take a look at it when I get to the car this weekend I will let you know Boss

[@anthonyarmenta1080]

What if the vent doesn't move? mine wasn't stuck or anything. no lubricant needed. its just not responding, no movement.

[@OTCLLC]

You may have to go under your hood look for your HVAC hoses small skinny vacuum lines either purple or white make sure they are getting the vacuum it needs it should open

[@drejackson1000]

Does that blow thru the side vents too?

[@OTCLLC]

Yes with all the vacuums hooked up should blow out like factory
