interior leaking in front passenger seat

good morning
not sure if people have this problem. It rained in the middle of the night. I got in my truck this morning to go to work. There was a little puddle on my front passanger seat. The windows and doors were closed. So I stopped this morning at this local conveniece store and i saw it from dripping by the blower fan... I can't see where it was coming from thou. Anyone have this issue before?? I had this problem ONCE upon a time when I had my altima where the water drainage were block( i think it was AC condensation) and it was spilling in my car... that was a long time ago, but I dont think this is the case.

 

On the passenger seat or on the floor?

 

its leaking into the floor.

 

AC Blockage. I'd wage money.

 

Spider webs, pollen, dandelion seeds, etc. I'd get the hose cleaned out and you'll be AOK.

 

so use high pressure water hose on where the windshield wipers are and blow it out?

 

Has nothing to do with Wipers.... when I was in the shop, the techs would take an air hose and small nozzle and insert it into the bottom of the hose blowing out all the junk. I've heard of people using a vac as well to suck it out.

 

insert it into the bottom of the hose to blow out all the junk... I guess I need to find where all this bottom of hose is... I got plenty of high pressure gas at work

 

Look under the truck in front of the passenger floor and there is a rubber hose sticking down. That's the drain for the evaporator. When debris clogs it the water backs up and overflows onto the passenger floor.
