Buick LeSabre Cooling Fan Don't Work

Q. Hi Vince, My radiator fan will not run at all unless I hook up a direct wire to the battery. The relay is good, I had it checked. I replaced the thermostat and coolant sensor. I also checked the fuses under the dash. Any ideas on what is wrong?

  • 1989 Buick LeSabre
  • 3800 engine
  • 127,000 miles
  • Automatic transmission
  • Fuel injection
  • A/C, Cruise control

Thank you,

A. There is a relay that turns the fan on. Also, the relay is turned on by the ECM. Either of these could be bad, so you better have it checked out properly so we don't guess the wrong part. The ECM will be over $150.00.
