2003 Zetec S - alarm problem. - mcyoon

Hello,

I have an intermittant problem with the alarm (factory fit) on my 53 plate Zetec S.
The car locks correctly ie press the lock button twice but the lights don't flash, then sometimes the alarm goes off a short while later.

Anyone had a similar problems or ideas, Cheers

Euan

dodgy door or boot sensor I would hazard a guess. does pushing on the door or boot cause the lights to flash after failing to flash before?

(idea comes from: you can pre-arm the alarm and then close the door on the mk3's, the lights should then flash)

I have exactly the same problem. Double locking does not result in an indicator flash and the alarm sometimes goes off up to an hour after locking up. I have taken the roof interior light cluster down to check the sensors for spiders dirt etc. All clean and well. This must be a common fault. Any result on a fix?

I think this may help.
Put the car into test mode by turning the ignition on whilst holding the heated rear screen button. When you release the screen button you should get a chirp. Now test each alarm input sensor ie door switch boot open close etc each should be greated by a chirp. This means the signal was received. I found that the bonnet switch was defective on my car this way. I suspect you may have the same problem.
