Omega 1999 2.0 16v CDX - Cruise Control

Hi All
My cruise control has just stopped working,
anyone know if it's on a fuse, or have any
suggestions.
TIA

If it's a manual box, check the clutch sensor switch. I've had that happen
(went out of adjustment)...

 

Any more suggestions gratefully received

Sorry - no other ideas (unless it's the brake pedal switch?). But there's
some really clued up & helpful people here, so support should be on its way.

Oh - just a thought - IIRC some people here were experiencing issues with
stalk switches malfunctioning the other week. Maybe they're a Vauxhall
weakness, whether fro cruise or radio controls etc.

 

Brake lights are working - hopefully that means the switch is ok.
Also I checked fuse 15 for the cruise control
and fuse 2 for the brake lights.
All other equip on both fuses seem to be working ok.
Once again Any info gratefully received.

The brake light switch has 2 circuits so even though the lights are working
it doesn't mean the switch is ok. If you find someone with a good scanner it
will show what is working and what is not - dealers have them but charge
more than smaller outfits.

 

Thanks me140
I'll see if I can get it checked out.
When you say 2 circuits, is that 2 separate sets of switch contacts in the
one unit
- could I disconnect and check it for continuity or reconnect and do voltage
checks?
TIA

 

Switch should have 4 wires on it if memory serves me right.
Ignition feed in that goes to the brake lights and the other 2 terminals are
an in and out for the cruise. The circuits inside work different way round.
When you put your foot on the brake pedal it makes a circuit between two
terminals to put the lights on whereas when you put your foot on the brake
pedal it breaks the circuit to the cruise so it turns it off (does that make
sense? I think the terminals are opposite each other so left and right will
do one thing and top and bottom the other. I retro fitted cruise to my
dad's 1999 Omega and it never played up.
Hope this helps.

 

Hi & thanks for reply.
Understand the first part no probs, but uncertain about:-
"I think the terminals are opposite each other so left and right will
do one thing and top and bottom the other".
Sorry to be dumb but I think I read that as Left & Right Top = 1 switch
& Left & Right Bottom = the other one, or is it the other way round?
Also I assume the switch is in the footwell above the sound proofing.
Sorry to be vague but its been too cold for more than a quick glance and
I'm priming myself for some warmer weather and its been more than 30yrs
since I seriously tampered with cars and they've changed a bit.
Is the switch repairable (I have the experience) or any idea of new price.
Really appreciate your time and experience
regards

If you look at the switch from the back the 4 terminals would make a square,
so the top terminal would be ignition power in (black) and the bottom would
be power to the brake lights ( will be black/ red or black/yellow - just
look at the wire that goes to the brake light in the boot) - and the left
would be cruise input and the right cruise output - cant remember the
colours but one side will go to the switch on the stalk and the other to the
cruise motor under the bonnet.
The switches are throw away cos they are sealed but only cost about £15.
It lives on a bracket near the pedal - take the trim off and look up -
awkward to get to. There is a real knack to getting them out. Where abouts
are you?

Long way from Yorkshire - unless you have a private jet????????

 

To get the switch out you need to press the pedal down as far as you can and
keep it down. Then pull the pin on the switch that usually touches the pedal
out as far as it will go - it will be a bit tight and make the sound like a
ratchet when it comes out. Next you have to pull the (red I think) tube
that goes round the switch pin out until you can squeeze the locking tabs in
to release the switch - all this while you are jammed under your pedal box -
OR you buy a new switch first and just smash the old one off.

 

Thanks for the excellent instructions - I like the last bit best.
Next day off not till Wednesday - if its dry I'll have a look then.
With ref to your last post ....................... I've got Tandem in
shed???
Thanks again.
