How to test cooling fan?

Is there a way I can test my cooling fan? Starting to get hot here in Florida, don't want to find out the hard way that its not.

The cooling fan should come on after sitting stationary for a few minutes or in slow moving traffic in warmer weather. Mine usually comes on when the temperature gauge reaches around a third of the way up. If it doesn't come on then do the following checks. Locate the fan switch on the bottom corner of the radiator on the same side as the gear shifter. Pull off the black connector, be careful as it's easy to break. Find a piece of wire around a foot long, strip each end & place one end in the connector & the other end against a good ground - one of the engine bolts is good. The fan should now run - even with the engine off. If it does now run then the fan switch is at fault - you could try cleaning the contact where the connector slides on before condemning the switch. If it doesn't run then check the following, fuse, connectors & wiring for any damage. Could also be the fan motor itself. Failing that, there is a fan relay sealed inside the junction box which is an integral part of the fusebox & is not supposed to be taken apart. However, I managed to pry mine apart once to fix a dry joint inside & then glued it back together & sealed it up with silicone sealant. Hope this helps. If you've any other questions then please ask & i'll try to help.
