Ho ho ho...
Well, last spring I found that the element in the driver's side footwell wasn't moving anymore, so I trucked on down to the local dealer where they said the element needed replacing (C$31), along with the vacuum switch-over valve (C$112). What do you know - winter is back with a fury. Are these items repairable (ie DIYer)?? If not, can I replace them myself? The dealer is charging 1.7 hours for the entire job - and I don't mind pulling this stuff apart myself.

For the money, I would let the dealer do it! This is money well spent and they will warranty what they fix.

Did they actually test the AC or they just "guesstimate"? Most likely the rubber insert inside the vacuum actuator went kaput. To replace the vacuum actuator (what model?) you have to remove the center console. It is a DIY but, it takes time.

Same model as you JH!
When you say 'actuator', you are referring to the element, right? The flap doesn't move at all. I don't know how thoroughly it was tested.

Same problem in my '75-280 sedan. Dash vents only. It'd be ok if heat fell. Any advice?
