Ford Galaxy - Cruise Control Not Working (2.0 & 2.3 Petrol Engines)

Hi All,

Over the weekend and after help from this forum, I managed to resolve the cruise control not working.

The below were performed on a Galaxy Mk2 2002 2.3 Petrol Ghia.

This is a quick guide to the common vacuum pipe or pump failure located behind the wing. It doesn't include pipe going to the cruise control servo or other vacuum pipes connecting beyond the wing.


Step 1

Remove and disconnect the N/S headlamp. Instructions can be found in the Library Contents,
or here https://www.fordmpv.com/smf2/ford-galaxy-reference-library/galaxy-headlight-removal-(mk2)/

Step 2

Looking through the gap between the chassis and wing

4271-0

You should see the vacuum pump. Similar to the picture below. A bright touch is ideal. This picture is how i found mine, with no vacuum pipe connected and would suggest the cruise control hasn't been working for some time.

4267-1

The first thing to do is check whether you have any holes / splits in the vacuum pipe. I would, as have others suggested replace the vacuum pipe with fuel line.
If like me, you have little to no vacuum pipe connected, see if you can salvage any of the pipe which is there.
You only need about 10 cm of pipe to perform tests. The typical length of the original pipe is about 20 - 25 cm.

Keep the pipe disconnected for now.

Step 3

Remove the vacuum pump from the chassis. The easiest way to do this is by removing the two 10 mm bolts pictures below.

These are locate directly behind the vacuum pump, accessible near the battery

4269-2

Now you will be able to pull the vacuum pump out from behind the wing. Be careful not to pull too hard as the pump is only connected by rubber grommets, and these are a swine to get back on.

Also, do not pull the vacuum pump to far, there is a power connector on there, when you feel resistant its probably safe to say you can remove it anymore.

Step 4

Ensure the power connector is sat securely on the vacuum pump as pictured below.

4273-3

No grab the two vacuum lines we held back in step 2 and install them onto the vacuum pump as below.

4275-4

There is no need to attach any pipes to the white outlets. These are the breather holes.

Carefully re-install the vacuum pump back to the chassis and ensure the bolts are fairly tight.

Step 5

No connect the outlet and return vacuum pipes to the cruise control system. Please see the picture for correct diagram. Green is outlet, red is inlet/return. These vacuum pipes should cross over each other.

To clarify, the plastic connector coming out near the wiring loom is the outlet pipe. This would connect directly to the vacuum pump.

The plastic connector which is to the right of the chassis (from looking toward the vacuum pump), this is the inlet/return and must connect to the pipe that is clipped to the breather (white) connector.

4277-5

Step 6

Re-install the headlamp, (ensure you plug it in). Check your lights to ensure you haven't damaged any bulbs.

Turn the cruise control switch to the off position. Start the car up, turn off the heating, stereo everything that emits a noise.

Now turn the cruise control switch to the on position, you may notice the revs increase/decrease slightly or you may be able to hear a faint noise. If so, this will be the vacuum pump creating the initial vacuum.

Now take the car for a spin. When safe to do so and above 35 MPH (i'd recommend going down a motorway / dual carriage way to do this), press the set button on the cruise control stalk.
You should feel the acceleration pedal move slightly from your feet.

If you do, your cruise control is now working. Flick the switch to the off position to turn the cruise control off, then perform the above a few time to ensure there is a good vacuum.

If you don't, press the set button a little bit harder and if safe to do so remove you foot from the accelerator.
Then press and hold the reset button.
If the car starts accelerating the cruise control is now working. Flick the switch to the off position to turn the cruise control off, then perform the above a few time to ensure there is a good vacuum.

If it doesn't, then take the car home and perform the next steps.

Step 7

Remove the headlamp check you have the vacuum pipe in the correct position.

If you don't, then change them and follow step 6 again.
If you do, then remove the vacuum pump again.

Step 8

Once the vacuum pump has been removed. Remove the two vacuum pipes we installed earlier.

Also remove the electrical connector to the vacuum pump. Note which pipe relates to each colour of wire.
Picture below

4279-6

Step 9

We now need to test if the vacuum pump is working. Sometime you need to perform the below twice as the pump may have seized a little like mine had.

Steps 9 - 10 are done at your own risk, and you require some form of electrical knowledge. At no stage should you connect wires whilst the ignition is on. Nor should you hold the vacuum pump whist current is going through it.

Using the appropriate size spade connectors and rubber protectors, connect each pin. Pin 1 (black) is the common/neutral.

I'd recommend using one black cable and two red cables that have 15 amp inline fuses.

Step 10

I'd recommend using the stereo wiring harness to perform the below test. You basically need a good earth and a single 12v line that is connected to the ignition. (This is for safety reason)

I cant stress this enough. Make sure that none of the spade connectors are touching! The must be protected by the rubber protectors.


ENSURE THE IGNITION IS OFF AND THE KEY IS REMOVED


Connect the black wire to the stereo's ground. This should be the brown wire there are typically two.

Connect pin 2 (one of the red wires in the middle) to the ignition switch on the stereo's loom. This is typically brown and red.

Turn the ignition on, but don't start the car.
If the stereo turns on, turn it off.

The pump should spin up. If it doesn't, turn the ignition off, remove the key.

Turn the ignition back on a see if you can hear a single tick. If you can't hear it don't worry too much its very hard to hear.

Then perform the same on pin 3 (one of the red wires furthest from the black cable). Do not have pin 2 and 3 connected at the same time.

If performing the above you do not hear the pump spin up, its likely the vacuum pump may have failed and would require a replacement vacuum pump. You may be able to clean it, but depending on how much water has got into it, it may be more beneficial to replace it.

If performing the above you hear the pump spin up, its likely either the vacuum pump is not receiving a current or there there is further damaged pipe. This would require more advanced investigation.
