Car: 1998 Mustang GT Convertible M5
Location: Trunk
Symptoms: Trunk light out, sequentials out. These get their power from the same source.
Side notes: I can jump the sequential unit directly to the battery (+) and they work. Same with the trunk light. I checked fuse 8 in the I/P fuse panel, it's good. I checked the 50A fuse under the hood, it's fine as well. Both have power and fuses are good as tested.
Possible Causes: Bad Remote Keyless Entry Module (I do not know how to diagnose this), Bad Upstream Wiring (I do not know how to trace this)
In my trunk on the harness that goes up to the third brake light and trunk latch assembly, one of the wires provides a constant 12V. When I test the wire with a multimeter when it's unplugged, it shows 12V just fine. When I test it for resistance, it shows a 0, no resistance. Now, when I plug it in (put a load on it) and test for voltage, it varies from 4V to 7V.
I'm not an electrician by any means, but I think some of you guys may be able to help me.
If you need any more information, please ask.
Thanks pally wally's! :SNSign:
