Hey everyone. Wanted to introduce my wife and myself. We bought a 2002 Jaguar S Type 3.0, 86,000 miles in March 2017. A Jag is my wifes life long dream car. We have had to do some work to it. A/C system, new battery, cat converters, damage repair from son in law running into the back of a truck. And new tires. It has a couple electrical issues that im getting so much info for on the forum. I'm looking forward to going to Florida in the spring and driving it home to Alaska. 5700 mile cross country trip. Anyway just wanted to say hi.

What electrical issues are you experiencing?
Re: Winter driving - In my experience from Oregon, we don't get much snow here, but enough ice. When the roads are bad, I drive my old pickup to work. Even with traction control, the poor Jag is just out of its element on slick roads. Can't blame the car one bit, though. I think it's the combination of relatively light weight, plenty of power, and an automatic transmission. Just be aware it's (fortunately) not a Subaru.

KR, im having issues with the boot open indicator on the dash. The radio has a mind of its own. No cruise control and no indication to anything being wrong. I took the bulbs out of the trunk so it wouldn't drain the battery, turn the radio off and with a jag why do you need cruise control. Never figured that one out. So I can enjoy the car without distractions. I really doubt I will drive it in the winter up here.
Rick i have 2 code readers one has abs too. Plenty of wire, solder and various tools to work with. I can hardly wait till i have it up here. Im sure my wife will have questions and I'm bound to come up with a problem I can't figure out. So ill pick brains for the answers I need. And thanks for the welcome.

Item 4 is there. But if you depress the switch with the boot open lights do not go out. I think there is a break in the wire going to or coming from the switch itself. I was reading about the wire bundle by the hinge that has too much flex and imagine thats a good place to start. I like having pictures of parts. Saving that one to my ipad.

For the "Boot Open" indication, be careful. If the control module thinks the trunk is open, it may not let the other various modules properly shut down for sleep mode. You could end with some modules staying awake and running down the battery. Removing the bulb may help a little, but the important thing is getting the rest of the car to sleep. I'd have to research the wiring diagrams a little to see how the switch and light are connected. It may not be a simple series connection, but more like the switch telling the module how to control the light.

Note how the trunk switch is not connected directly to the two trunk lights. The switch sends a signal to the Rear Electronic Control Module (RECM), which in turn provides a ground to turn on the lights. So I'd say if your trunk lights had been staying on, even though you've since removed the bulbs, the RECM still thinks the trunk is open. I'm not sure of the logic involved, but I'd be willing to bet large sums of your money that the rest of the car is not properly entering sleep mode. If the car is not driven everyday, this could be running down the battery.
Unfortunately, the wiring diagram is not clear if continuity through the switch means the trunk is open or closed. You'd have to play around with a meter to be sure. This would determine if a broken wire (at the hinge area?) could be causing the false "Boot Open" indication, or if it's the switch itself at fault.
For the clockspring, see sections 3.4 for the cruise control function, and either 15.1 or 15.2 for the audio controls. In Jaguar-speak, the clockspring is called a cassette in the wiring diagrams.

Do you know anywhere to get the cassette/clockspring? What I am seeing I need four to replace them for the radio and cruise control. According to the wiring diagram I see a connector on both sides of the cassette. Please correct me if I'm wrong. Are they hard to get to? Where are they?
