Question about 1997 Volvo 960
Posted by Anonymous on
You probably notice that it blows through the dash UNLESS you accelerate hard, then it's floor and defrost vents that gets the air.
It's a ~$40 dual action bellow sort of up over the gas pedal that is malfunctioning. You can put a band-aid on it by removing the kick panel over the pedals and then plugging the yellow line going to the bellow.
To replace it (per Volvo) you have to remove most of the dash! That's expensive and a pain in the behind, plus you probably will have rattles in the dash after.
OR you can cut a hole in the air box where the baffle connects and replace it, then patch the hole with the 'lid' you cut out and duct tape it back on.
Nobody will ever see it. :D

Some thing you could look at would be this. The control is usually fed by a vacuum line or small hose thats is connected to your intake manifold.
With a cold engine,look for a skinny vacuum hose that runs from the intake toward the fire wall . It should be going inside the cab and connecting to the A/C vent control.Some times the hose becomes disconnected or splits or cracks due to heat under the hood.
Thats usually the trouble.
I hope this helps you.

its a problem with the switching mechanism. you have to look up under the dash to see if you can see where the switching mechanism is. if you can not see it from there youll have to remove complete center dash
