Aniie,

what year is your van? I have an '86 owner's manual I can scan for you.

the seat track lever, and the entire system can be buggered and cause
what you are experiencing. It does mean taking seat out, and looking
underneath at mechanism. If you want pics I can send them.

Also, there are plastic inserts in seat tracks on the van, not the
seat. Its possible they are damaged and causing problems.

The rear heater has a separate fan control, again shown in owners
manual. Also there is a valve on  heater itself, so that coolant flow
can be shut off during warm months.

Let me know if you want the manual and pics of seat.

It's not necessarily the track - we did take it out and lube it up a few
months back. The problem seems to actually be with the lever itself. It
doesn't seem to work correctly and I don't know if it's because it's
broken
or what. Having not ever seen another one, I don't know what they're
supposed to look like.

Is that something that can be replaced? If so, where do I find a new
one and
how do I go about getting it installed and the old one removed? Or maybe
I'll just replace the seats. I've thought about doing that as these ones
aren't that comfortable for me since there's no lumbar support. I do
have a
lumbar cushion but due to the size and angle of the steering wheel, I
can't
use it without being too close. If I put the seat back a notch or two to
compensate for that, I have to stretch my hip too far for the gas
pedal and
that defeats the purpose of the lumbar support! LOL - no I'm not just
being
nit-picky - I am disabled due to a back problem and if things aren't
in the
right position, my legs go numb. Not fun to drive that way.

Also, someone in an earlier post this morning asked if I have an owners
manual. No, I don't, unfortunately. There was one for sale a while
back and
I was too late to grab it! Sure would be handy to have one and I am
keeping
my eye out for another but they seem to pretty hard to come by.
