I changed thermostat control sensor but fans don't turn on

Asked by Dec 28, 2014 at 08:10 AM about the 2003 Buick LeSabre

Question type: Maintenance & Repair

1 Answer

I think its a duel fan deal. Long time ago on a 91 regal I never noticed the fans had died untill they both went out.. I suppose unplug both check voltage. If none swap a good known relay. There is one with the same part # by that relay. .
