'91 200Q: various sensors and switches

[Arun Rao <rao@pixar.com>]

Well, I finally purchased the Bentley books for
	my '91 200Q last week, and have been spending some
	time curled up with them (!). Some answers, even
	more questions ...

	1. Turbo coolant pump/rad. fan after-run: Bentley
	says, turn on engine, let it idle until fan turns on,
	and then shut it off. Coolant pump and fan should start
	after about 5 minutes.
	
	Well ..  they don't. Shorting the wires from the switch
	does indeed cause them to turn on. Is the switch bad
	or was it just not hot enough? Seems to me that they're
	depending on the coolant temperature to rise when the engine's
	shut off -- which I find odd. Shouldn't the darn thing start
	running immediately after shut-down?


	2. The oil pressure warning light has been coming on intermittently
	(more frequently recently) for a several months -- gauge reads normal
	values, oil level is fine. Bentley is somewhat sketchy on this:
	is the low-pressure switch in the same module as the sender for
	the dash gauge?  Does the warning light turn on both for high
	and low pressures?

	3. The windshield washer warning light has been turning on
	spuriously as well. (The animation's cool, but gets old
	very soon!).  Anyone BTDT?


	TIA!

	-Arun
