Is the fuse in the underdash fuse panel or under hood? And what is the fuse #?

Customer: replied 1 year ago.
23 under the hood it's a 2002 Town & Country, previously I said it was 2001 but it is a 2002. I can run the car all day long and it won't blow the fuse but if I put it into drive and put under load as long as it's heated up for at least 20 minutes it will blow the fuse. I change the fcm, the ignition switch, the ifm, but have not changed the BCM because everybody saying is just for the power windows door locks so on and so forth. Being that is not a dead short and that is intermediate, it's really giving me a hard time. I was wondering if you've ever ran into anything like this before.
Expert:  Cary York replied 1 year ago.

Fuse# ***** also supplies power to the Sentry Key Immobilizer Module. Here is the location. Lots of moving parts in the steering column. Tilt, turning, etc. I would check for broken/grounded wiring. Move the tilt up and down to see if you can get it to duplicate.

I will check that tomorrow, it really only happens when the engine is hot and has been running at least 20 min (normal operating temp). Confusing cause its not a dead short, and it is resetting it self with in 2 min. Wish me luck lol, will be a very happy camper once I do find this thing.
Expert:  Cary York replied 1 year ago.
One other thing comes to mind. You said it happens when you put the car under a load. The engine torques when you put it under a load. so there is movement under the hood which could move Omar and harness if it were grounding out. You can try doing a wiggle test on the harness under the hood. Wiggle the harness and see if you can get it to react. I have seen harness problems underneath the fuse panel under the hood near the transmission .

ya already check that for sure. I am wondering if there is some kind of sensor other than the input or output sensor for the transmission.

Sorry. I have to opt out.

Hello and welcome to JustAnswer!

Do you still need help?

Customer: replied 1 year ago.
Found some wires under dash showing signs of heating up (pw). Following these from ignition to bcm, it is the only component I have not changed.
Expert:  sprinkles08 replied 1 year ago.

Any wiring showing heat damage should be replaced, soldering the connections and sealing the splices with heat shrink tubing.

Customer: replied 1 year ago.
I think I am good right now will do some rewiring and double check harness also, and change the bcm. Had it running for about a hour before it happened again, as soon as I got it above 60 mph, I could smell burning under dash, it lasted for about 5 min like that before blowing fuse. I installed a fuse breaker so I could continue driving without having to change fuse.

Let me know how it goes and if you need any more help. Good luck with the repair!
