If it sticks OPEN, the engine will never warm up properly, you'll get poor economy and the heater will never warm the vehicle.
If it sticks CLOSED the engine will overheat, possibly causing damage. If the engine gets hot enough the head will warp and you'll need to have the engine disassembled, the head will need to be resurfaced and you'll need to reassemble the engine using a new head gasket.

Follow the top radiator hose to the engine, what that mounts to is the thermostat housing, remove this and there is your thermostat. * ** *** **** ***** Actually, on my 1997 SL2, the thermostat is on the bottom radiator hose. I would check the "Saturn Thermostat Pictures" link below, which also has installation and removal instructions.
on the passenger side of engine, below ac compressor. coming from bottom radiator hose.
A dimmed headlight is usually cause by a bad ground. Check the connections in the headlight wiring. Sometimes they can get water in there and just a little bit of corrosion will cause bad connection.
Nothing...........there is none.
The Thermostat is inside the goose neck, just follow the hose from the radiator to the goose neck, unbolt the goose neck. Look inside the goose neck and you will find the thermostat.
follow the 2 water hoses off your radiator. one will lead to a housing containing the thermostat. usually has 2-3 bolts.
i there a switch on a saturn that would cause it not to start Yes the neutral safety switch.
Purchase a ECTS for around ten bucks....easy to replace.
