Hello peeps just purchased a zafira b. Lovely car to drive and looks nice too. It’s got panoramic roof and sat nav which I live about it.
Couple issues I have and was hoping I could get help and advice on solving them. Sorry if these questions have been asked before.
1st. When under load and hi revs power fluctuates. Found w split vacuum pipe on top of engine which though problem solved but still no different.
2 the radio signal is very weak.
3when trying to open passengers window from drivers side switches window doesn’t open when it’s fully closed if u open it slightly from the passenger switch u can open it all the way from drivers side no problem. U can go up and down no problem but soon as it closes all the way it won’t open again.
4 the big button on radio doesn’t function properly. When trying to select stuff on radio I.e moveing bass or treble up and down it only goes on notch up or down no further so having to use the steering wheel buttons.
So far that’s the only issues I’ve come across.

I appreciate any help and advice you guys can give me.
