On Sis in law's 1998 protege with 1.5L DOHC engine. The fan does run when AC is on, but do not run otherwise, even when the engine is approaching over temperature.
Sis in law replaced fan relay in fuse box on LH side of engine bay. There is +12 at one side of the relay coil, and +12 at common of relay throw. Energizing relay coil on bench throws relay.
The engine coolant temperature sensor is replaced, before replacement engine temperature gauge did not move, now it warms up rapidly.
This car does have two radiator/condenser cooling fans, I'm not sure which/both should run on engine temperature, and which/both should run on AC on.
Thank you so much for any wisdom here. This is one of those jobs where compensation is good will/love, so we've got that going.
