Water leak inside the car

Don A has an excellent answer, but if you have a sunroof, that is more likely the reason. The pipe runs down between the door pillar and the windshield and there is often a join there which can part. Be careful with compressed air as it can blow joints apart.

2002 Nissan/Datsun Altima 3.5L SFI DOHC 6cyl

The Fuel Filter is located: Under hood, driver side, rear engine area, passenger side of master cylinder, mounted in fuel line

have 2002 altima,blower works no heat at idle and very little heat when accelerating.I changed carbon cabin filter,made sure little gear under dash to temp knob wasnt broken,flushed and bled system.Nothing worked so checked hoses to heater core and found inlet hose was hot,outlet hose was not.So investigated this problem and came to conclusion heater core was clogged.An easy way to check is to get car to normal running temp. put on heater and blowers at full.Go under dash on passenger side where counsel meets firewall,this is where heater core core inlet and outlet aluminum tubbing go through firewall,you will be able to feel both tubes one closest to you is outlet, so if this one is not hot and and other is your heater core is clogged.I detached both inlet and outlet hoses to heater core from water control valve.Then I blasted water with waterhose and nozzle set at jet,first through outlet hose to blow gunk out,then through inlet hose until water runs clear.Reatach hoses fill and bled system.heater works great nice and hot!

the drain line for the sunroof is clogged up again probably did not get all the junk out if it the first time

4- 600 rpms idle maybe

Heater core is leaking.

Sounds like your drain is pluged. The drain is on pass. Side on fire wall. More than likely will have to get under car to find it. Try shooting some compressed air into drain port

where your battery sits look inside there maybe some twigs and leaves blooking the drainage holes look all along there i had similar problem on vw passat no arm in looking hope this helps?good luck

You probably have a clogged drain for the evaporator. The evaporator would have to be removed youmay have to have a professional perform this.

there is only one thing that leaks water there, that is the AC condensation drain, water forms as part of the AC cooling the evaporator core, this water must be drained away or it will flood onto passenger area, so there is a drain on the passenger side at bottom of firewall, will leak allot of water depending on how humid the air is.
