Sonata ventilation

Just had some work done on my 3lt V6 '98 Sonata (engine and
transmission gaskets replaced and windscreen washer bottle replaced).
Problem I now have is that the air from the dash vents only comes out
to the windscreen and not to any other vents. Before I take it back to
see the mechanics who did the work is there anything simple I could
check for? (As the repairs were done by different mechanics I would
like to know which one may have been more likely to have left
something disconnected so I can go back there).

check all vacuum pipes from the intake manifold are connected.

 

In particular, you're looking for the vacuum line that goes through the
firewall.

 

Thanks for responding..... but can you give me a hint on where to look
in the engine bay for this line? top/bottom/left/right? Where should I
see this line?

Had a good look around and could find nothing that looked as though it
should be connected. Took it back to the mechanic and it took him
about 20 minutes to find that he had cross connected 2 vacuum lines.
Working fine now.
