Fans aren't turning off

[stefcio007]

Have to wonder if it was loose wiring on one of the sensor causing the issue and all the fiddling as fixed them up!

I think you might be right, it's gone bad again.
But I can't get any resistance from the brown sensor at all, might be on its way out? I'll be pulling them out tomorrow so that I can test them properly. Maybe the coolant has affected the wiring? Is it corrosive?

so, turns out the sensor was held in place using silicone and I also had a leak coming from the water pump.
All fixed now!

Sorry for bumping an old thread.
My "fix" for the fan issue had been to keep the 20A fan relay fuse removed because the issue eventually came back randomly.

Didn't know what the fuse was for and didn't appear to change anything when removed.
Today driving and wondering why the AC wasn't working. Turns out that fuse has to be in there otherwise it won't work.
Basically comes down to two things. AC sensor or fan relay module.

I don't mind the fan coming on during the hotter months since it "should" come on if it's hot, even if it isn't hot and it comes on, at least during summer it won't bug me when it happens.
