I have an 04 F150 SC and have had water drip from the drivers side grab handle. I had the stealership repair that and now after a big storm last weekend my whole center section of the back seat was soaked. I'm guessing the water was coming in through the rear brake light. Got to schedule another fooking service.

Anyway, those of you with warranty running out (like me), thought I would share.

Did Ford go cheap on sealant or was my truck built on a Monday or Friday

1. Turn the fan motor (climate control motor) on high, in the non-recirculating mode.

the test worked for me

 

Hey thinks for the info

 

You know that test did not work for me but I the dealer replaced my light due to a leak. It only leaked (where I noticed) during hard rains and unfortunately in the car wash with my son in the back

Anyway, be sure to look at your trucks as they have a issue here...
