front right/passenger side leaking h2o!

hi Taco-world!
I will send intro later, but have issue and looking for answers...

I bought 2007 Tacoma from a friend almost a year ago. At 128000 miles, 4 cylander, I have been getting about 26 MPG, just took first longer road trip. Great truck!

Issue: The passenger side front has been leaking water. I just had the Electical unibody system replaced by Toyota ($4000). They just inspected for leak ($128) and could not find cause. Even looked at cowl, "dry".

Is this a common issue w/Tacoma's? How is it fixed? Dealer servicemen stated it would not have issue or cause electric problem to repeat.

I don,t like water getting into the truck. Any ideas for resolution?

Thanks
tomg

 

AC drain clogged. Look way under and up in the front pass side engine compartment. There is a drain. It's clogged.

 

I had to replace my cowl as part of a tsb to stop the water. Happened on heavy rainfall and washing the truck.
