My 1998 Chevy Silverado has a water leak on the passenger side floor
board of the cab coming from the firewall and fan motor areas when it
rains really hard and when the truck is in a certain slope position
while it's raining.
I have tried everything I know to find the leak and can't seem to pin
point it. I was going to have the window re-sealed but the glass guy
said that it wasn't the window causing it.
I should let you know it's not from the heater core nor are any of the
drain areas clogged.
I have read earlier comments from July 2003 post entitled "98 Chevy
cab water leaks" which states a screw in the cowl area that could be
causing this but for the life of me I can't seem to figure out what
their exactly referring to. Does anyone have any thoughts on this? And
not to sound dumb but what exactly is the cowl?
