since water is still dripping right at the passenger side carpet from somewhere under the grove box every time after car wash or heavy rain. i am going to check the drain tube for the sunroof and also the windshield trim. does anyone know how to remove the trim to check the drain tube at the A-pillar? Also, how to remove the windshield trim to check for sealant crack?

mine is a 93' max sohc automatic

 

a pilar inside is clips, just pull off. the windshiled is a urethane seal, therfore you have to cut it out and have it re sealed. i would check your cowl vent first. take out the vent, fill the cavity with water, if its filling you have a drain problem there, flush out the sides and ure good.

 

check the door trim seals.. they're the most common to fail, as you open and close them every day.. way more often than any other part on the car...
(think of how many zillion times your driver's door has been opened and closed over the years. it's amazing they still stay on the car.)

 

Where is the Cowl vent? I have seen this term a couple times, but i still don't have an idea of where it is and how to access it..

 

open your hood, behind the hinges, where your wiper arms bolt into is called a cowl.it runs the width of the car. that allows air to vent into the car providing it with clean air when the ac or heater are on.
