i have the same problem as PHL172. in fact everytime i go onto a volvo forum the same problem and symptoms seem to appear.along with the same answer--blocked heater matrix.
as this is quite a long job i would love to know if this has indeed cured the problem.
this is very rare on other makes, i wonder if theres any reason, other than longevity why the 740 should be so affected,

as i gutted the interior of mine when i first got it a few years ago due to water leaks- mainly footwell vents-not too thrilled about doing it again.....

Re: (douglynn)

Did this. (reverse flush ) worked a treat Phew....


sorry george didnt see this thread untill after i had replied to mine


Got to be carefull not to use to much pressure tho, just incase something blows
.

Have had this happen on a few cars (mostly older models). this has by far ben the easiest to fix. must admit the thought of an interior strip down was not one i looked forward to.

Take it easy guys.

Phil.
