Dome Light/Full of Water

everytime it rains my dome light fills up with water and drips into my truck...... what cud cause this? i know alot of people say there back glasses leak at the top around the 3rd brake lite ..... what i dont understand tho is the headliner dont get wet.... also my truck has 2 rubber plugs in the roof i guess from where somebody had some antennas on it .....

thanks fellers

 

More than likely it's the back window leaking.

 

yeah probably the back glass leaking. you might want to try the plugs on the roof first though, put some silicone on them and see if that helps.

also, check to see if you carpet is wet in the back under the seat too, this will tell you if it's the glass

 

wonder where i cud get some new plugs to pop in?

 

Front windshield probably or rear break light letting it in.

 

wudnt the headliner be wet tho?

 

i would think so...weird

 

it doesnt have a damp spot on it ANYWHERE
