Oh No! My faithful 2002 Sable with a 3.0 6 cyl started overheating this week. While sitting in the garage with engine running, the cooling fan motors will not run. When I switch the a/c to on, the fans kick in. I changed the ECT and even the WTS (sigle wire) myself since they were easily accessible and relative inexpensive. Still no help.

Any help on figuring out why the motors wont kick in and/or why my faithful daily driver is hot? Thx!
