just started doing this after 1 year of working properly. always on when the truck is running whether hot or cold. It's a JLP setup. wondering if it's the sending unit stuck on, or if it could be a bad relay. Also, there's a little silver electrical component under the relays that I don't know what it is.

Any ideas?

Bueler, anyone, Bueler??

 

undo the sensor wire and see if it stays on. Simple. Eiter that or just put a continuity tester on the sensor and see if it's grounding all the time. If it is, then the sensor is no good. If it's not , then your know the relay is sticking.

Good luck.

 

Good idea, thanks. I'm going in.

the temp senders are cheap!

 

It's the antifreeze bath that I don't enjoy!

 

I heard my sensor "crack" when I installed my built motor last year....I kept my fingers crossed hopefully it was okay...but the fan stayed on all the time ....and I had to take the "antifreeze bath"...I feel your pain
