Still not resolving the cause of my battery low voltage at the beginning of a day but which increases after a short trip to the post office 8 miles away and back to full, and under the advice of my over-puzzled mechanic, I avoided to burden it with the use of A/C. However during a very hot day I pressed the A/C button and it did not work. Then I pressed the blower button and it did not work either. Already under the suspicion that mice might have busied themselves by my cabin air filter as it happened in the past, I opened the cowling panel and I made strange discoveries: Beside the mice abandoned nest in front of the cabin air filter, I found the filter itself very wet from the rain obviously slipping under a more than 1/8 inch space between the cowling cover and the windshield and a very strange wiring ending at both ends with very strange terminals having both two huge holes. From here I have now two new problems beside my old battery problem which, btw, refuses to retain the charges of my Schumacher charger/maintainer:
(1) how to make a better adhesion between the cowling cover and the windshield, and
(2) what are the two pink terminals of the strange wiring under it.
Please help me if you can. Thank you.

 

No idea what the wire is, but my 07 also has it just sitting there. Maybe a rain sensor we don't have?
The wet filter is common. I took the plastic piece off that holds filter, removed the failed seal, applied caulk and reinstalled.
Mine was actually getting inside and fogging windows.

 

Some cars had a heated front windshield,Its for the heating element in those

 

Thank you Telewubby, interesting, but the terminals are not connected to anything as for the purpose of a heating element. So I am not completely out of the dark...

 

If they are indeed the wires to connect to the front window de-icer, I read in this forum a few years ago that a member when he replaced his broken windshield got the one with the heating wires in it. He connected the wires, added 2 relays in the hood fuse box and when he hit defrost it not only diverted warm air to the windshield but powered on the defrost wires. I remember asking him at the time what the relays were, I just don't recall now. He said (he thought) all Jags were prepared for the wired defroster windshield (IDK if that's correct) .
