As the title says, we arrived home late last night, shut off the engine and the electric fan was still running. Seeing as it was only 55° outside and the fan never runs after the engine is off, I immediately pull the fuse for the fan and call it a night.
So after some time on google, I find the most likely cause is a bad fan relay Sorenson Part # 41-5330 and I find a good website showing where it is and how to gain easy access.
So I replace the the relay and test the system by starting the engine and turning on the A/C and within a few moments the fan turns on.
But what I find strange is how hot the relay gets so quickly up to about 120° F in about 10 minutes. I did notice the relay is built on a heat sink which would indicate high temperature is normal but I would really like to test the fan for current draw.
Does anyone know what the correct current draw on the fan? The fuse is a 40 A but that should be to cover the startup current which is significantly higher.
