2019 Tacoma Sport 4x4 pre collision + lane departure system malfunction and blower motor not working

Pre collision system malfunction see dealer, lane departure system malfunction see dealer, and blower motor stopped working.

I had something interesting and mind boggling happen to me a few days ago. Both the systems above and my blower motor all had issues and the engine seemed to be in a limp mode and idled as if to have a miss. I looked for a fuse for the blower motor, a relay, and none are clearly marked for "blower motor". Anyway, after taking the blower motor out, bench testing it, and deciding that it couldnt have been the blower resistor, I found the cabin fuse box just behind the hood release latch down by your left knee (pain in the butt to open btw) started pulling each fuse until I found the one labeled "IG1 NO.2" red 10 amp fuse was blown. As seen in the pictures, its the 4th one down on the right side. I was puzzled because nowhere is it clearly marked that the fuse would apply to all 3 of these issues and everything I found online seemed to be a nightmare with dealers blaming it on lifts, plows, bigger tires, ect... I was so relieved that it was an easy fix. I hope this helps anyone that comes accross this issue.... anyone needs help please reach out.

 

I'd ignore the first two and fix the 3rd

 

Er, his post explains how all problems were due to a blown fuse, and everything is now fixed.

 

ture. I would just find the first 2 totally unnecessary

 

You guys are missing the Point. What I'm putting this up for is if anyone is having this issue, the fix is just a fuse. But dealerships seem to be having an issue finding the cause. People are replacing a bunch of un necessary parts and paying for labor and the hassle all cause of this. I was unable to find any info online for these issues above. When we have mechanical issues, we all go on YouTube, Google, here, and call friends... well since I was unable to find info, I figured i would put it out there. When ur truck goes into limp mode and starts throwing all these messges, causing u to wonder wtf is going on, I'm showing that its an easy fix and no need to panic.

 

I’m having the same issue with my 2020 Toyota TacomaTRD Sport 4x4. I had just finished installing Meso customs Puddle pods and put everything back together and started my truck up and found the same error messages on my dash. I’m out of luck for tonight but will be trying to replace this fuse tomorrow and see if my issues go away

 

thank you for providing this information. hope i never need it but helpful if i or others do.

i never looked and probably should but will ask, are there spare fuses in the box or did you have to supply it?

 

What comes to mind is the possibility that the blower motor when starting is consuming too much inrush current. I'm not sure but it could be connected to excessively dirty air filter? Anyway good to know about.

 

Thank you Sir , this is what the forum is about learn and share . I appreciate this kind of of information since I have some electrical issues I will look into this fuse .

 

Glad this fixed it for you but if you're still under the 36k warranty it may be worth getting this checked out. Fuses usually don't just blow for no reason.

 

Thanks for for this.. I just had same issue! Saved me a lot of time!

Have you had the issue come again since?

 

This happens during heavy rainfall lol and the snow. I wish they didnt add this to truck, would save us some money. I am sure those sensors add up at least 2-3K to the truck.
