Blown fuse has caused problems

I was hooking up a small trailer over the weekend and due to some faulty wiring on the trailer I blew a 30 amp fuse. I pulled most of the fuses looking for the bad one and in doing so I now don't have a heater, seat heaters, steering wheel heater and now I have to manually use the release trick to get it out of park. I have an appointment with Toyota but not until next week. Does anyone here have any suggestions?

 

So you are pulling random fuses and not putting them back once you confirm they are good?

 

No, I checked each fuse and put them back where they came from. there was a blown 30 amp fuse in the passenger side fuse box that was bad.

 

Have you replaced the fuse and disconnected the battery for several minutes and reconnected?

 

Yes I did. After replacing the fuse I did disconnect the battery for 30 minutes. Nothing nothing was restored.

 

You may have blown another fuse or relay in the process of removing and checking them, or the same/initially replaced fuse has blown again protecting the circuit. Replace the initially tripped fuse or relay with a confirmed equivalent good one removed from a working circuit. There may be another issue. At least check all of the currently dead circuits you lost. You may want to buy a few spares to troubleshoot with rather than cannibalize your current good ones and making the problem worse.

 

Forget your appt, just show up.......
That's how its done...

 

Vehicle Interior Seat Heaters have 15 amp fuses each:

 

That's good advise, although I have tried everything you had mentioned except for checking relays, I'm not sure how to do that. I bought a collection of random fuses yesterday which had a small fuse tester with them, made it much easier to test each fuse. They were all good, although I still don't have power to any of the heater related functions, along with the Park issue.

Do you have more than one fuse box,I have a second gen and it has a fuse panel under the instrument cluster.

 

Removing and re-installing each relay may fix a contact/connection issue and bring things back to life. Also, try wiggling all of the connections and see if that wakes anything up. I see your truck is a 2024. Is it still under warranty? It's kind of early for any electrical glitches and having more than one circuit out is troubling this early on. My reason for suspicion being a relay or connection is the multiple failures you are reporting. I would also disconnect the negative battery post before doing any troubleshooting.

 

@caribe makaira a little help please?! We’re lost without you.
