Thread: Cruise Control Faulty

check the engine bay for the cruise control bladder, might be a small leak or the air line running from it may have perished from engine bay heat

Is that the big black vacum unit on the throttle linkage ?

Ok I checked the vacum lines there ok the bladder thing on the throttle linkages is ok BUT if I take the line from the T piece and the vacum line that leads under the Jack there is no vacum hold and if I blow through it you can hear something that sounds like a duck I can breath in and out with no restrictions. Is this normal or does it indicate what ever is under the jack is faulty ?

Can someone check with there Landy Discovery so I know if I have to get a new part or not I don't know if it is normal or not it's very easy to check.

Just look around the window washer bottle for a T peice vacum line one comes from the fire wall one goes to the bladder on the throttle linkage and this one goes along the LHF gaurd down under the Jack. Remove this from your T peice and see if you can blow or suck air freely or if it has vacum hold or restricted when blowing air.

This will tell me if mine is stuffed or not.

Er, the D1 CC is notorious for crapping out. 7 out of 10 times it is the hoses - just replace em all as it is cheap enough. The other times it will be the pump.
There I said it!

All vacum lines have been checked and are ok no leaks I can hear the relay click on so it would seem to be the vacum motor as I pulled it out from it's small cavaty under the car jack in the engine bay I pulled the plastic cover off the motor and marked the shaft with black texter went for a drive got back home looked at the motor and the mark is still alined it hasn't budged an inch so I would say it's safe to say it's the vacum motor.

Ok turns out after replacing the vacum motor that was not at fault same result.

So would I be looking at the control box or the steering wheel ? I think this is were the fault now is. How do I get the steering wheel off without setting the airbag off.

Ok I got around to replacing the CC computer and still no go so what should I be looking at now ?
