The car (97 Integra, 2Dr) runs fine, except that when I pulled into
the garage the temp gauge shot up to 3/4.  Found some cooling steam
hissing out.  And the fan motors (both radiator and AC) are not
running.  Following had been tried:
1. Turned on A/C - both above fans ran, so that proved
 a. In dash fuse is good.
 b. Relays are working.
So the most likely culprit is the thermal switch (cooling temperature
sensor, near the lower coolant hose.

The questions is that I cannot disengage the connector of this sensor.
It has a colorless plastic cap, and I don't see any way to remove
(disengage) it to check it by ground the green wire.  How to take the
connector apart?

And then, If I know the location of the fan relay, I can check that
too instead of at the ECT switch above.  Where is this relay?  Is it
under the dash, or is it under the hood?

Thanks..

And, to Tegger - Thanks to the excellent FAQ.  However, I need more
info on reading the REMCO diagnostic under the cooling section.  I am
using XP-with IE 6.0, but I see all kinds of text (and codes) all over
the screen.  Does it require Java, VM, javascript, activeX, etc,
turned on, or...

Thanks.
