so i dont know what is up because for the wholel year ive driven it, it maybe turned on twice and that was a very long time ago. not sure how to check the relay since i thas 4 prongs to it.
that being said, i dont know if my thermostat is good or not. is the lower radiator/collant tube supposed to be colder than the top one? or should both be fairly hot?
the top one, i can hardly hold it as compared to the lower one.
i have this weird idling problem when i step on the gas, the rpms drop to about 300-400, sounds as if it is about to die but usually recovers.
here is a video of it:

The radiator fan only turns when the coolant reaches a certain temperature to kick on. The AC fan is on whenever the AC is on.
First, I would check to make sure there are no bubbles in the system which may be preventing the fan from functioning correctly. Then, I would replace the thermostat. They are so cheap, that you might as well. You can test it by suspending it in water and looking to see if it opens when the water reaches the temperature rating of the thermostat.
Where does the ECT gauge hover when driving normally?
About the idling problem, when was the last time you did a tuneup with new wires, spark plugs, distributor cap/rotor? Have you thought about running a bottle of injector cleaner through?
Sorry I couldn't be more help. I will flip through my service manual and see if I can find anything relevant to your problems.
