My ac/heater fan just started running even when the truck is off. Different but similar issue. I’m trying to find the fuse to pull to make it stop. It ran the truck completely dead overnight.
I'm having the same problem. I've tested all my relay and there good. Changed my coolant temperature sensor. They still only turn on with the AC. I'm thinking the PCM is not sending the signal to the relays
You are awesome thank you The relays were my problem
I'm glad to hear that.👍
Fixed the same issue by disconnecting the battery waiting 15 min reconnected EVERYTHING WORKS I kid you not!
Thanks this is exactly what I was looking for!
No problem
Going to try this tomorrow! Thanks for sharing!!

Pull the #40 fuse out and it will stop
I replaced all 3 of mine but they are still running what do I do
Mine too 😡
@@Edenolivia21236 ended up taking it somewhere could never figure it out
Maybe ect disconnected or bad.
Did find the problem?
@@Kelo64244 unfortunately not, I had to take it to a shop
On my truck is the opposite, they won't turn by themselves
Mauricio Hernandez same problem did you figure out what it was??
Until now no but i have to turn on the AC so they can turn on
Me too I have the run with the AC on for them to work...
I was thinking on putting them direct so they will be on all the time because it loses power because of the AC.
