Vauxhall Astra H SRI 1.7CDTI - Tailgate warning Light and Courtesy Light not Show - Lance82

Hi all,

I have an Astra H 2006 1.7 CDTI SRI

From the subject heading you've probably realised I'm having trouble with the tailgate open warning light. It doesn't show when the tailgate is open and the courtesy light doesn't light up either. The warning light does show when the driver and passenger doors' are open.

Things I've tried:

1) Swapping the build from the glove box to the one in the boot (Nothing)

2) Removing the tailgate latch, taking it apart to see if I could spot the problem. I even removed the micro switch but that's a sealed unit so can't check inside. All seemed fine in the latch, however.

3) Using a piece of wire to check the connection for the tailgate latch by placing it on the connections and the other end of the wire on an unpainted section of the car. (Nothing)

I'm at a loss as what to do next so any and all advice would be great.

Thank you in advanced.

Lance.

The micro switch in the tailgate latch sends an earth signal to the rear electric module , located in the left rear of the boot area . The wire could be broken where it runs through the rubber tube fro body to tailgate. The colour of the wire is black with a blue tracer colour .
