Just purchased a 1985 L/C FJ60 thats been in the same family since new. After driving it home, I noticed what seemed like an electric fan running after shutting the engine off which was a blower motor, in the engine compartment, on the driver side fender well. This thing stays on for up to 20 minutes before shutting off. Does anyone know what the purpose of this thing is for? It appears to just blow air into the engine compartment
