The thermostat opens at 195 F degree, and if the cooling system runs properly, then the temperature will stay the same because the radiator will exchange the heat to air stream. If the radiator is partially obstructed, sometimes only 15%, or there are air pockets in the system, or the water pump is giving up, then the temperature will increase.

The evap system may be located right next to the fuel tank. You'll most likely see a can, hoses, solenoids, etc.

I hope this points you in the right direction! :)

Does anyone make an oe fan switch for a 1994 pont grand prix 3.1 that turns the fans on, between 190 to 200 that will shut them off at 180

The vehicle computer turns the fan on and off. It determines when to turn it on from the signal it receives from the coolant sensor. It does not turn it on at 190 or 200, that is barely normal operating temp. it usally comes on around 225. To run the fan at those temps. would not be good for the performance of the engine, it would make it run to cool, so I don't think you will find your switch from an OE source.

1999 pontiac grand prix gt dual climate control not working prope

The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.

Replacing 90 pipe assembly part on 1997 Grand Prix GT

If its the same as my GTP, its just under the Supercharger right in the middle of the intake.
Just pull it out, its only held in with a O-ring. When you replace it, make sure you lube the gasket with grease so its easier to put back in, and less likely to nick the O-ring.
