Hey to All,

I have a 1972 Oldsmobile Cutlass Supreme. I have been getting my A/C repaired on and off for the last year. Every time I take it to get looked at another issue comes up. The issue I am having is that my A/C blows under my dash but will not blow out of my dash vents on any level "low or high". The A/C guy says he doesnt know what the issue is at all. I have the new version of the POA valve and I've had my vacuum lines looked at by him and he still does not know the issue. Could anyone help me with this. Thank you in advance.

 

I sounds like there could be an issue with the blend door assembly under the dash. There are 2 or 3 diaphragms on it and if they are all not functioning correctly you won't get air anywhere but the floor.

 

Ok. Thank you. Do you know where I can get the diagram for those. Also, would my dash half to come out to fix that issue?

 

I'm not really sure about what would have to be removed to get at it, but I think it can be removed without taking the dash apart.
The diagrams can be found in a chassis service manual which I highly recommend you pick up.
