SOURCE: leaking moonroof onto passenger floor

I would lean more towards one of the drain tubes being disconnected. You will have to get into the headliner to check. Your leak is in the front, I would remove the sun visors and the trim on the windsheild pillars, this should allow enough room to see it the drain tube is loose. The drain tubes usually push onto a nipple at the front of the track, if it's loose just push it back on and secure with a zip tie.

SOURCE: Has anyone had wet carpet on passenger side?

Hi Robert:
Most likely the drain tube for the a/c is plugged.Sometimes, you can take a coat hanger and slide it up the tube to remove the blockage. If you look on the passenger side firewall under the hood, you should be able to see a 1/2 rubber hose coming out of the firewall. This is the a/c drain tube, try to get the coat hanger up it gently, if this is the problem, water will likely come out once you do this. If you can't get the hanger up there, then you may have to pull the carpet back and you will see where the tube connects to the heater box. You will have to pull it off there and run the hanger through it. You will get wet, so bing towels. If you unhook it under the dash, you will need them to soak up the water.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I've goy a 05 Buick LaCrosse CXL 3.8L that acts like its not getting any gas then will take off like it was floored.Idle at stop is erratic

You need to remove the air hose from the throttle body and get some throttle body cleaner and a tooth brush. My Lacrosse started to hesitate then lunge around 100k miles or so. Cleaning the throttle body completely resolved that issue. Get the cleaner and spray it in and use an old toothbruch to gently scrub the body and the plate. I would put a towel underneath the throttle body as plenty of black liquid is going to come out.

I have a problem with my fire wall leaking coolant, it seems to be comming out of one of the hoses that lead to the heater core.but i have no loss of heat and i cant smell anything from the vents.and i was...

Do you have coolant on the front passenger floor board? When heater cores fail it will leak onto the floor board and mist coolant on the windshield. If you have a loose clamp on the heater core hose it's possible it could be leaking down the firewall into the passenger compartment. If you don't have coolant on the windshield check the clamps / hoses first.

Passenger side floor board is wet.

Hi Big,

Heater core is on the passenger side under the dash.

Are your coolant levels low?

Start your engine and set the heater on high. This allows circulation through the core. Now check for leaks. Place a paper towel or two on the floor. This will allow you to see the color of whatever is leaking. (e.g. antifreeze)

Fogging will only occur when there is a temperature differential of more than one or two degrees between the inside and outside of the vehicle.

Best regards,
Mike
