Electrical issues, help!
To begin with, I bought her used about 2 years ago. At that time the dealer had someone fix a trunk issue. The 3rd brake light did not work and the trunk automatic did not operate. He kept is for almost a week and it worked. Something in the wires in the trunk where it bends while opening/closing.
So several weeks ago the 3rd brake light stopped working again. Last week the trunk stopped opening and closing for me, but it would release and if I pushed it down the motor would close her tightly. Yesterday my battery was too dead to crank the engine. Got a jump drove to the auto store had the battery tested, it was inconclusive. He thought something was still on somewhere.
So I told him I would go home and charge her overnight and bring it back for testing.
I did not follow through with my part today because my back hurts, but it stayed on a battery minder all night and day.
So this evening I got to digging around inside of the trunk and found a poorly taped wire had come lose. That was the # 3 brake light, so it works now.
The other wire they had repaired has a shrink tape on it with a lump in the center, so I think it is OK. The push button on the trunk now lights up but does not work. Sometime it will make what sounds like the motor run for a bit then stop, no trunk action. Pretty much the same at the door control. After pulling the spare tire out and checking some fuses in that area and pushing and pulling on other connectors on the left rear, the trunk no longer pulls itself down to lock. I now have to close it all the way and I hear no motor mechanism at all. Oh, I cranked her up a couple of times today, now the battery will not turn over the engine. Back on a charger!
The battery is less than two years old.
Also the driver window does not go up when I close the door, since the Auto Store disconnected the battery to test it.
Thank you for assistance here!
