<5KCSTQ> Stage 2 cooling fan help...

Ok - got my after-run cooling system back on line (well, sorta - but it
checks out).

1. Low speed works in after-run.
2. Med speed works when it gets up to the "tick marks" past 1/2 way point.
3. Med speed does not work when AC is on except when 2. applies.
4. High speed works when relay is over ridden. (Since there isn't a high
pressure problem in the AC).

Fan works in all speeds if relays are overidden - so no relay problem
expected, resistor is good.

All I can think of is the big doubleswitch thermoswitch might be bad (the
one in the radiator). But I can't see in the bentley where a signal from the
AC turns it on... Plus it still works, except the constant run feature w/AC

Any ideas???
