Default Cruise Control Had Never Worked

Besides the Hella Fog Lamps not workinhg (another thread) I have never been able to get the Cruise Control working on my 2002 Disco II

What are somethings that would prevent a Cruise Control from working properly?

Thanks,

Landy II

Default Landy Girl :C.C. issue

Search threads, this is common. Check for a vaccum leak(worn rubber hose) under hood. Easy fix.

Also, does the cruise control switch light up when you turn it on, if so I agree replace the vacuum lines.

Just open the hood and look underneath just at the back of the wheel well. You will see the rubber vac hoses. I finally took a look at my daughter's car after two years and it took almost five minutes to fix.

No light when I turn it on. Ive got the Rave CD to look up where the vaccum line is. Maybe another problem to take to my local Land Rover guy and have him trouble shoot it, but I'll do the fix

I'm taking the Hella fog light problem to him and I'll see what he says about the cruise control. Maybe it's a problem that he can point out and I'l do the fixing on!

My cruise control light comes on, but nothing happens with the controls...vacuum line also?

Where are the vacuum lines located? It's the last line item on my laundry list to get this thing back to full working order.

I found a line that hooks to a diaphram that seems like it is supposed to be hooked to the forward throttle cable. There is a 1/4" gap betweent the two at the moment. Vacuum line that hooks to the back of the diaphram is in good shape. It looks like there is an open fitting at the bottom of the canister that the line starts from...maybe that canister has no vacuum becasue of the open fitting...or is the throttle cable supposed to be attached to the diaphram. Don't have my camera available until Friday, but I can try to take some pics with my phone to show what I am talking about.

I just found my diaphragm and the vacuum hose is missing there was a small 1/2 cm rubber cable that was perished pretty bad, where should this hook up to?

I just figured it out from looking at the RAVE there is the unit underneath, however I had no cable present other than a nice perished 1/2 cm piece of rubber on the back of the diaphragm. Thanks all

Wow, 6 months with no cruise, and within 10 min of reading this thread it works great!
Vacuum lines the culprit, and knowing where they are... priceless.
Thanks all
