Fuse occasionally burning out, car starts in limp mode.

Hi all,

So I've been having this problem for a few months now. I go out to my car in the morning and it will start in limp mode. After a quick inspection I see this fuse is blown and change it. After clearing transmission codes it starts up normal again. Now I don't recall the. Ode it gives while in limp mode, but it has to do with the safety neutral switch I believe. So I'm wondering what you guys think can be causing this? The fuse the burns out is the missing one the arrow is pointing to. I also included my fuse diagram. Thank you.

The fuse is #31 and is for Backup lights, Cruise control, and something with the automatic transmission.
What you need figure out why the fuse is blowing and then trouble shoot that wiring until you find the issue.
So, start with a good fuse and start the car out of limp mode.

Leaving car in park, turn on the cruise control and press all the control buttons.
Turn off the car and check the fuse.
Fuse still ok?

Start the car put the car into reverse.
Turn of the car and check the fuse.
Fuse still ok?

Thanks for the reply. I use all cruise controls and reverse everyday without the fuse going out. I only find it blown in the morning when i go out to my car. I did take your advice and tried to troubleshoot it that way and the fuse is still good.
