Fixed it'03 sedan failed it's spring fan operation check
Both fans are working on both speeds when powered directly. Both run on low when I jumper 2-3 on the rad thermo switch, but don't run when I jumper 1-3. Fuses test good.
This points to a bad FCM, but is that test definitive? Is FCM failure common? A new one is $pendy
Turned out to be a poorly crimped pin in the FCM power connector. How it lasted 20 years like that is a mystery.
Cheap fix + AC for the wife = happy life
