that means your not getting your fan control from ecm, is there a check engine light on?

No
Expert:  Mechanic01 replied 1 month ago.

you might have a bad coolant temp sensor but it should be throwing a code for that, heres the location of the ect sensor, check the wiring, pull the connector check it and the sensor, if they are ok ill send you the tests for that, that what tells the computer to send ground to relay which your doing with the clip
