I recently got a 97 Civic and noticed that the radiator fan isn't coming on. I checked the voltage on the fan plug located next to the radiator overflow reservoir. I got nothing. Is there supposed to be constant power to that plug? If so where should I go from here?

no the fan is switched by the PCM on the power side, voltage will only be present when the fan is commanded on by the computer, start with basics checking the fuse and the relay, also hook a test lamp at the radiator fan connector ground and battery positive to check for a good ground, if the test lamp illuminates your ground is good. if all that checks out it could be a bad pcm, broken wire between the pcm or a bad fan motor. if you could get your hands on scanner that performs bi-directional tests that would be ideal to see if you can manually command the fan on
