Electrical problem
1998 Buick Regal V8 Front Wheel Drive Automatic 115000 miles

Used the diagnostic machine to check why the check engine light was on it shot out code P1651 which is the Fan 1 control circuit relay. Where is it located and how do I change it?

Cooling fan motor relay number 1 isl ocated in the underhood electrical center, pictured below..

Simply pull out relay, much like removing a fuse, then replace with new relay. Thanks for using 2CarPros.com!
