2022 Limited electrical issues

I have a 2022 tundra limited, 65k miles on it just out of warranty and now im getting odd electrical issues.

Intermittent wipers and the washer sprayers don't work. Interior lights behind the buttons and the ones in the center console cubby do not work. When its not so cold and it gets to 55 degrees and sunny things will work while im driving but they will turn on and off on bumps. This has been a really good truck but this is getting frustrating because I cant find any information.

I have been studying the wire diagrams and am wondering if its a bad ground but not sure where the ground cables are inside the cab. Thank you for the help if anyone can help me

 

I had a somewhat similar situation with one of my Tacomas. The cruise control would randomly turn off. After a year and it slowly getting worse, I went under the hood and started randomly squeezing connectors together. One of them went "click" as I squeezed it. The cruise control was fine after that.

 

After you confirm cables are good, tight, no breaks or corrosion, Do a volt and load test on the battery. Factory batteries are good to get 3 years of service. Unsure of where you live, but with the cold temps most of the country is experiencing, any battery issues will announce themselves.

Low volts or a battery going out, bad cell, will induce all sorts of odd issues, alerts, etc in Tundras. It can be hard to diagnose seemingly unrelated issues with different truck systems....but the reality is they need a certain about of volts/current and any drop in the required power can cause strange things to happen.

Id do that first, if it all checks out....then I would start looking at the truck wiring for rodent damage and check connections for the components having issues.

 

Thank you for the fast reponses, ill check battery

 

AC Delco batteries you are lucky to get 2 years out of. I run Interstates in my boat....same batteries since 2012

 

So I just checked all the connections even under the steering wheel and also checked the grounds with multimeter. Everything was good. Battery is at 12.88V when the truck is off 14.27V when the truck is idling.

Also found out my memory seat function isn't working, rear view mirror adjustment not working, all the back lights for buttons don't work, wipers and washer isn't working and finally the fog lights not working. This truck has been a work horse for me but I hate that once the warranty expires I get these issues.

 

Sorry for your troubles. Unfortunately, I can't help you.

I will say, this is exactly why I chose to get an extended warranty for the first time in my life. These trucks are basically a computer with wheels, and I know my limitations with electronics.

 

Ditto to the extended for the first time

 

Wanted to give an update, following the wire diagram i noticed two blown fuses. didnt make it to the store but will try it tomorrow
