I have a 2006 1500 megacab. when it rains or through a car wash the grab handles leak out of the top screw. I have seen some TSB saying it is the door weather seals. some say it is the drain tube from the sun roof. this is coming from both sides. soo.... whats the deal. help me please

 

i had this happen to me once, but only once, i took the pillar plastics off and had somebody pour water all over the suspected area and i couldn't get it to leak, so i buttoned it all back up and have not once had water leak ever again. it was weird stuff man.

 

Mine was caused by the sealer at the top of the windshield not sealing.
Water was getting behind the sealer that keeps the windshield in place, then running out of the drivers side grab handle from the bottom bolt fixing and plastic cover.
I just re-sealed the top of the windshield with new black silicone sealer and everything was fine.

Did you have the windshield replaced or is it the factory installed windshield?

 

I don't know TBH??
I haven't replaced it but.......I bought the truck used.
