Water leaking into passenger side floor --seems like something is clogged with my AC lines --temp excellent but water is leaking into passenger side floor board

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.

Sounds like you have found your problem, on the fire wall down low on the passenger side there should be your drain most are a elbow rubber type hose check it and I believe you have your solved. Good Luck Mike

You have a cracked condensation pan on your AC or a bad hose (could be cracked or clogged). You'll need to remove the dash to investigate which it is.

ac drain pipes are on the passenger side front floor area (just about where your feet go) under car when cars heater core gets a hole in it lots of times antifreeze will leak inside car on floor try to get a small sample of fluid thats leaking out with a tissue or something (white In color) see what color fluid is ,see if fluid is slippery like oil or not (rub it between fingers)
Antifreeze= orange or green in color
Transmission oil = red or brown
motor oil = brown to black
washer fluid = Blue or drk orange
ac condesate= clear water (cold)

sounds like your drainage tube may be clogged look under the hood on the passenger side of the car see if u see the tube if so try to see if u see anything blocking the end

The usual problem when this happens is that the drain line from the AC condenser is plugged causing it to fill up with water which eventually finds a way out and drains onto the passenger side floor. It is fairly easy to fix but requires getting underneath the car on the front passenger side, locating the drain line, normally a flexible hose coming down through the frame roughly below the dashboard. and running something like a coat hanger up through the drain line to remove the blockage. Beware that water will start to run out the hose as the blockage is removed.
Some cars have this problem more frequently than others and you may have to repeat this procedure every year or so. When it starts dripping water on the passenger side again it's overdue.

Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

You can only have 2 issues dripping water onto the passenger floor board. First being a clogged drip line for the ac evaporator. The other is a leaking heater core. Figuring out which one is the issue is fairly easy.

If your vehicle has anti freeze in it when you turn the defrosters on it will smell sweet. If it does you have a leaking heater core. If it does not then the drip line is clogged.

To clear the drip line get under the vehicle and snake the drip line on the firewall. It usually is a 90 degree rubber or plastic piece on the passenger side about a third of the way up the firewall. A leaking heater core means it has to be replaced and not really a job for someone that is not exsperienced.

Yes, you have a drain line on the AC unit in front of the passenger seat, it comes through the fire wall and it gets clogged easily, find it, clear it and no more wet floor. It will flood the floor if you don't. Check it out.

This means your air conditioner drain tube is clogged. This will take about a hour shop rate to repair or if you look behind the glovebox you will see it. Thanks
