COOLING FAN 900 1993

Had car for almost 2 yrs now, cooling fan has never worked on high speed, jumped both low/high pres stats, fan came on when as advertised. Checked temp switch on radiator with car running, there was no change in resistance. How can I tell if I have a plug in type of switch or screw-in type.

    There is a way to use the DTC device that reads trouble codes for testing certain functions and one of them is the fan at low and high speed. There should be info in the FAQ.

    If everything is fine with your car the fan should only run at low speed, the high speed setting is for near overheat situations.

    Check out the FAQ for the steps to run the test and that should put your mind at ease.
