Strange oily film on inside of windshield

I've done a lot of mechanical work, and the heater core is probably one item I would almost pay someone else to do. Realistically, first time out, it's a 6 hour job, but doable. If you bypass the hoses, make sure you run your U-hose on the hard heater lines, dont loop the dead core together instead (how it sounded to me). You could just not use the heater/defront until you swap it, it doesn't circulate through there unless it's on.

Not a 6 hour job, I did it in 3 by myself.. If you know where all the screws and bolts that need loosened are it makes it much faster. There is a good write up here somewhere that I used..

Yeah that's what I was thinking. I actually was thinking about putting an ad on Craigslist to do this job for money. I was always told its a 6 hour job, but it isn't

Yes, it's a heater core.
Yes, it's a pain in the ass.
Yes, it can be done with common tools.
Yes, it will likely take a 1st timer 6 or more hours.
No, the carpet doesn't need to be wet for it to be a heater core. If the A/C drain line is working, then a leaking core would be draining into the front of the engine bay. Look in the bay and look under the car for signs of coolant. You'll find it, even if it's a small spot.
