INTRODUCTION:
Some 2005 - 2010 model year Tacoma vehicles may exhibit a condition where the interior carpet has become wet or water is found in the interior due to water draining into the cabin from the rear window. This condition may occur in heavy rain or while in a car wash if the rear window moulding seal is covering the rear cab drain vents, allowing water to enter the vehicle.
Use the following repair information to correct this condition.

NOTICE:
As a precaution, apply a shop towel or rags along the base of the interior of the rear window channel to catch any water that may flow into the cabin during the test.
