Hey everyone,

I've been reading up on folks who have had the same issues, namely, the concurrent horn failure and cruise control failure on a Disco Series 2.

My CC and horn went out around the same time, ~135k miles. CC would work intermittently, but has now completely failed. I've replaced the button on the steering wheel, CC pump under the hood, to no avail.

What is strange is that the horn is also inoperative. I've read that a rotary coupler may have failed and could be causing the issue. What do you think?

Thanks,
Taylor

 

 

 

The 10 amp fuse to the horn that sits under the hood is looking good, still fresh. (I vaguely remember a year or so ago pulling the fuse and the horn going off, should I have expected that this time around?)

ohh yes, the stereo controls don't work, nor the head unit itself (prob separate issue). I have a newly refurbished head unit on the way.

No SRS light illuminated.

another fun fact I can pose to yall is that my disco has had leaking from the front sunroof (definitely regretting getting the sunroof option), and we have had monsoons down here in Georgia. My AC line also leaks badly and frequently soaks the floorboard. But I ain't drivin' without AC, its GA in the summertime. hahaha.

still love this truck though!

 

X1 ............. most likely the rotary coupler behind the steering wheel, so steering wheel off jobby.

 

Just to add some additional perspective to the thread, when I first bought the truck I noticed that the radio/clock fuse was continually blowing. Fuse 16, near the top on the right side stack under the steering wheel with a label to read the manual. I probably went through 5 fuses in the first two weeks. I finally figured out that it was connected to the tilt steering wheel. I set the wheel where I like it and haven't adjusted it since May. It hasn't blown once in the last 2,000 miles so I assume some part of the harness is chaffed/cracked and shorting out whenever it flexes. My issue may be completely unrelated however if you've got the wheel off you may want to inspect whatever harness feeds the rotary coupler too.

 

no that is an excellent point and certainly didn't think of that before. I'm gearing up to take the steering wheel off, but font know exactly how to go about it. I have the rave manual, are there procedures for that kind of thing?

 

Hey all,

Glad to report that the rotary coupler duly fixed the horn & CC issue that I've been having. Getting the steering wheel off was somewhat taxing (it didn't want to slide off) but actually quite fun and interesting. All is good now, and it feels great (and weird!) to have Cruise Control again. haha. Thanks all for the help.
