Flashing Glow Plug Light And No Brake Lights

[roverlloydy]

I've got a X plate Galaxy and I have a constant flashing glow plug light when I am driving and my brake lights don't work. I have checked the bulbs and they are fine and also I have replaced the brake light switch and that has had no effect. Anyone any ideas what may be the issue??

 

Thanks

iirc you may have to set the plunger?on the switch.

 

take a look in the faqs in the technical section of the forum,on correct replacement of switch,also iirc there are 2 switches,you may have replaced the 1 what wasnt knackerd.

Some vehicles have two switches a black one and a blue one, and as Gregers said may need adjusting, if you still have a problem start by checking for power supply at the switch.

The switch I replaced was a black 4 pin one....will there be another switch?? If so where??

 

I replaced a blown fuse for the brake lights, the new one hasn't blown but I still have no lights

If you have two they are one above the other, check switch for power supply and adjustment.

Interestingly I had exactly the same problem on a Mk2 Galaxy, flashing glo plug light and then no brake lights, so if you found the fix I'd be very interested to know what it was that caused it. Faulty brake light swiches shou;dn't cause the glo plug light to flash, so its unlikely to be that anyway

Look what I found... The glow plug light doubles as the engine management light on the diesels, quite often this is a faulty brake light switch so check and see if the brake lights are working correctly, will also have left a fault code which will pin point the fault.

Amazing what you can find isn't it ;)

Further investigation of glo plug light/brake light problem indicates that the wiring loom to the tailgate can break, also check the rear compartment where the car jack is usually kept, there is some wiring and a connector there which can get damaged. Also, the grommet which carries the brake/cruise switch cables through the front bulkhead can wear, causing the cables to short (not very common I'd have thought)
