Leak help

2020 Tacoma keeps leak when rain. However, ONLY the back floor board oddly.

Already, had dealership take entire (hard to see your truck this way tell ya) but entire interior out to track this. Was said to been leak top driver side windshield, addressed and put back together. Less one month later a good rain and now both rear floorboards vs just driver side.

I am aware of a cargo light recall for 2016-2019s... They said it looked dry, now "I am" not so sure.

This truck is my treasure and my peace mind get away.

It is my hope there may be others with same (2020 Tacoma double cab SR5) issue and point me into what I or they may not be seeing.

Any tips greatly be appreciated. Thx

 

Welcome To TW....
only way I know is to start wetting it...and follow to the source..most I've seen on here are 3rd brake lights or roof racks

 

Welcome aboard! Hope you get it figured out. You might try posting your question in the 3rd Gen section.

 

Welcome aboard! Sorry to hear about your water leak. Assuming there is nothing mounted on the roof, the most likely culprit is the cargo light. I would remove that and look for evidence of water in/around the housing. It might be as simple as a leaky gasket/sealant. But if you post in the "3rd Gen Tacomas" section, you will get more help. Good luck!
