[200q20v] Running Hot

[RICHARD MEZIC]

While driving my '91 200q wagon this past Sunday in 90deg heat through
stop-and-go traffic, my temperature gauge was well above normal and the
warning indicator came on as I (fortunately) got close to home (ran the
heater to draw heat off of the engine).  Any ideas before I get home and run
the "codes".  Fluids are topped off, cooling fan came on after I parked...

My wife now reports that the climate control system "surges" - blows hot
when windows are closed, ac pumps when you roll down a window.....?

Thanks in advance!  The "list" always comes through.
