I got the AC working on my "new" (Pearl) SVX, heat does appear to be coming out of the upper vents on it. On my other (Black) SVX, heat comes out for 2 seconds then there a "shooowut" sound as some vent closes and then nothing at all comes out of the upper vents.

I've heard this is due to something melting in the mixer or something (and a get an error code pointing to the mixer door or something like that). If you get no heat out of the top vents, it might be worth checking the diagnostics.
