If you're not sure your fans are working, turn on your air conditioning, there is a bypass that turns on the fans to extract heat from the condensor so your car blows cold air.

Try doing that and see what happens. You could also try getting a haynes, or chilton manual and seeing where the fuse is for the fan and if it's not working you could try tapping on the fan with a hammer or blunt instrument to see if the motor is starting to build up high resistance (if it starts to run). There should also be a relay that controls the operation of the fan, so if you don't have much experience diagnosing electric concerns, replacing it is pretty inexpensive and it will garauntee that the relay won't fail since you just replaced it.

If you do have an ohm meter, measure the relay accross terminals 85 and 86 (stamped on bottom of relay in small numbers) and you should get between i believe 50 to 80 ohms. You can then put a jumper wire to one side from a + battery source, and a - lead to the other side to activate the relay (hear it click) and measure resistance accross the other terminals. One should read 0 ohms resistance, two of those terminals should also read like that without hooking up power to the relay (but these terminals aren't used anyway).
