I have a couple issues I've been trying to figure out and could use some help with. (1) None of my car door speakers work but the front and rear do. Are there any fuses that control the door speakers? (2) I cannot find the location of the horn fuse or relay. Is there a fuse for the horn? If so, where is it located?

 

Capital,

I don't have direct answers for you, but these links may help.........

There are no fuses for the speakers. Each speaker connects, via its pair of wires, to the Power Amplifier (I presume you have the Premium sound system). Only in the case of the rear door speakers, the rear door tweeters are connected to the wires of the mid-bass speakers then the two share the same pair of wires to the amplifier. There are also inline connectors for the door speakers - CA10, CA12 etc. as shown on the diagram (their locations are as shown on the second page of the attached diagram).

When you say "the front and rear" speakers work, do you mean only the A-post tweeters and the sub-woofer at the back work? The original Jaguar premium system has no "front speakers" other than the small A-post tweeters. I would first check directly at least one of the "non-working" door speakers to see whether it is perhaps blown and, if good, check the speaker wires from the Power Amplifier end to the speakers. If not in the speakers themselves, the problem could be in the amplifier or in the wires or the in-line connectors to the speakers. But, it is unlikely that wires to all 4 door speakers are bad. Possibly someone forgot to plug-in the in-line connectors, or the amplifier has failed. It is also possible that all 4 speakers are blown, one by one but only really noticed when the last one blew.
