cooling fan relay

Yesterday I noticed my radiator fan was not coming on as it got hot. I put a couple of jumper wires from the battery to the fan and the fan works. I traced the wires back to a 5 pin relay. The question is, is there a way to test the relay? Thanks

Year, make, model? The relay is cheap--you can start there!

Possibly, your local AutoZone might be able to help you with testing the old relay.

I knew it was a GM--I have replaced many of these--let me guess the fan does come on--just way too late?! Try this for a quick fix to prevent overheating--turn your defrost or ac on--it will kick the cooling fan on!

I've already installed a switch from the fan inside the car. The fan doesn't come on with the air on or off. I will replace the relay. What I want to know is how is the relay tested.

The relay is checked with an ohmeter--but you have to have the specs on the relay!

Redneck is right...you need a service manual to determine what's what on the relay...pitch it for a new one...you're talking 20 bucks.
