Question
Hi, I have the above and the Electronic fuel flap, trunk lid, central locking, and windows will not work. Fires relays and switches have been checked. Also digital dash seems slow to start operating. Car is in the Uk so any help greatly appreciated. Thank you.

Answer
Hello,

I have run into this before, but for the life of me, I do not remember the answer at the moment. You are dealing with one circuit.

Since you are in the UK, I would highly recommend spending $30 US to get the complete service manual for your car. You can go through the diagnostic flow charts and fix this problem. The manual is a download good for a year and since you are in the UK, you can give this information to any mechanic too!

Good Luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
