I believe I've got a bad thermo switch/sensor in my 1995 Honda Civic LX. The
radiator fan does not come on when the AC is switched on (though the
compressor fan works okay). I checked the fan relay by putting 12VDC across
the coil and I hear a click, plus I get continuity across the contacts. I've
bent the pins in case the socket connection is bad. Shorting out the
contacts in the fan relay socket causes the fan to come on, so the fan
itself is okay. That's the disgnostic work I've done so far.

Thanks to Tegger's FAQ, I've been able to locate the thermo switch, but I
cannot figure out how to remove the connector for testing purposes. It's
rotated in such a way that I can't see do undo the connector, and help here?

Aside from the connector, are there any pitfalls I should know about when
replace the thermo switch? It's fairly easy to get to, so I should be able
to do it myself.

Also would like to change the thermostat, but never having done that I need
some assistance. First, in locating it. Then in determine what type it is
(med temp/high temp) and removal procedure. I've read that on later model
Honda's it's on the lower radiator hose but I can't see it.
