Fan won't work

Ok if I jump it the fan goes on. But does not go on with a brand new fan relay. I have change it three times please help…:angel:

It’s a 92

If your talking about the rad fan, check the ECT, [Engine Coolant Temperature] switch. 94

Which 1 that?

Not sure where it is located on your car, either at the back of the block or around the thermostat, it is the yellow/green lead at the rad fan relay, to test, use a jumper lead to supply a ground to that lead at the relay plug, relay must be plugged in and ign. must be on, [power at the black/yellow]
If the fan turns on the ECT switch is bad or the wiring from it to the rad fan relay is bad, to test the wiring, ground the yellow green at the ECT switch, if rad fan works replace the ECR switch. 94
