Default Leak

Hello Everyone,
I have an 07 GT Convertible.
I have been turning this car into a show car the last couple of years, and I had it up on jack stands installing a part when I noticed that I have a leak.
This is always garaged when not in use, (maybe 2000 or 3000 miles a year). There has been nothing on the garage floor or driveway.
The drivers side wheel well and under the drivers side door (floor area) has something dripping off of the underside.
It's green/yellow in color, feels oily and has no smell.
I checked the oil and it's fine. Antifreeze is good, and it's Orange. Brake fluid is full. Power steering fluid is full.
Transmission is dry everywhere and so is the engine.

I have always kept my cars leak free. What could this be?
I don't see anything leaking.
Could it be the AC lines? I do fill it about every year at the start of summer.
I just put new wheels and tires on it about 1000 miles ago and this wasn't here. (I would have noticed)




Any input you have on this will be more then welcome.

Thanks,
Dan

It's certainly the right colour and texture to be AC oil.

If you are recharging the AC every summer, then that is your leak. My 06 has never been recharged from the factory and still blows cold. You should not need to recharge your AC every season.

The car is in its hibernation mode. I will look for this before next summer.
Thanks

Gotta agree with this statement. I still have the factory AC charge, and I bought my 2006 new back then...AC blows cold.

There isn't much on the driver side. (drivers side under the floor and front wheel well seem to be wet/dripping)
I think there's only a couple of AC lines, a Receiver/Dryer, maybe an Expansion Valve.
Are these the only things on the driver side for the AC?
Can I buy these off the internet and swap them out myself?
I have the vacuum pump and everything needed to re-fill it back up?
I replaced the compressor 3 year ago and would like to keep the AC running good.

Maybe a video somewhere that will point me in the right direction?

Does anyone have a diagram of the AC system? I want to replace everything except for the compressor
and condenser.
