So, after finding this thread, and a few more it looks like I am suffering from the same pan drips as everyone else. Let me clarify, that my drips are coming from rain water as well. I took some photos of the process of finding these small cracks for the next guy this happens to (Something tells me I wont be the last.) And to save him time, here is how I discovered my AC Plastic Cracks:
Step 1) Remove the plastic interior shroud attached to your interior roof (phillips screws)
Step 2) (photo 1) Find drip on Metal plate. They will find the lowest point (it could be coming out of a screw hole)
Step 3) (Photo 2) Using a 10mm socket and a drill bit attachment, because these are long bolts, remove 3 long bolts that attach metal plate to ceiling. Note: By removing these you are removing how your AC is attached to your ceiling so dont try and drive off. And another more IMPORTANT NOTE don't try to tighten these bolts up with your drill, just torque them by hand. There should be a "50% gasket compression."
Step 4) (Photo 3) Find the black, plastic drip pan, that connects to a hose feeding out to the "drivers side" of tow rig
Step 5) (Photo 4 Back side) Look for small hairline crack(s). I found a total of 3 in my plastic piece of crap drip pan. I removed the grey caulking around the tube to get a good look at whats going on in there.
This is where I am stuck
STEP 6 Where can I find a new plastic drain pan, or what should I patch these cracks up with that will be a long term strong fix. I am all about doing it right the first time...
