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.....
