The sunroof switch or control module may be faulty and not sending the correct signal to open the sunroof. If i had to put my money on something, i would bet on the wiring that goes from the car to the boot. if it doesnt open easily, a little bit of a cleanout or grease (WD40) inside the latch normally does the job...

Once i got the tailgate open, i was able to visually inspect the wiring a little and couldn't see anything obvious but given the time of night and i was working with a torch i didn't want to try removing the grommet to do a proper inspection of the wiring so that is something i will do when there is more time and better light. So did mine, until I pulled the part out that goes through the body inside the car which is where all the flexing takes place.actually, i have been able to open the boot by releasing the catch with my finger - not sure if something has been removed from the garage visit, but i don't remember there being as a big a gap before. however this doesn't really help as i cannot see any obvious wiring breaks at the small loom at the joint. I also can't see any obvious way to remove the pod at the top of the tailgate to get to the break light. Ok, so after some research I have been able to almost conclusively determine we have a fault in the wiring loom for the tailgate. The wiring between the hatch and the body was in a real mess. Made up a new loom and it still didn't work as reliably as I wanted it to. My centre brake light also did not work.

Vauxhall astra twintop boot wont open? - Fixya SOLVED: Vauxhall astra twintop boot wont open? - Fixya

Clearly some "expert" had been in there before me and had used loads of electrical tape to "fix" the issues. When i had the same problem as you, on my Zafira B, i used Opcom, to do an actuator test of the boot release motor and it opened. Turned out to be the microswitch. It might sound like a random question, but, on the GTC, is the boot button on the keyfob supposed to work?After the service we had the car at another garage for something unrelated and asked them to look into the tailgate issue and they said it could take hours to determine the fault because of all the work that would be required in getting to the mechanism.

Got it sorted ta, popped off the panel as per advice, gave everything a fiddle and it seems to be working fine. There could be a few reasons why your sunroof on your 2011 Vauxhall Astra Twintop 2 door is not opening and instead beeping when you try to open it. Some possible causes include: the astra convertable is prone 4 this problem take it to vauxhall there is a rework and it wont cost u a penny!!Whilst every effort is made to ensure the offer details are accurate and up to date, Vauxhall reserves the right to change offers at any time. All offers are available at participating Retailers only. As above i have a 2007 astra h twintop and the boot will not open, operate the switch and nothing, also the convertible roof wont open either, when driving it dings (very annoying) Not sure on the B, mine was held in by lots of plastic trim clips and 4 screws. You will break some of the clips so make sure you get some spares. My story in list form, boot light off - followed by boot not opening 2006 Astra 1.4sxi 5 Door hatch. Essentially the only thing that happens is that the car refuses to unlatch, if someone presses the open button.
