Sounds like the condensation drain isn't working.  Water backs up, probably
freezing  onto the evaporator core and blocking air flow.  On the B13 there
is a rubber hose low on the firewall under the hood that the water drains
out.  If it falls off, the water will drain into the passenger floor,
rather than outside (found this out the soggy way!)  I'd check that.
