The blinkers don't work, it won't Boost the blinkers won't work the wipers don't work the sunroof won't open the boot latch won't open with the button inside the car. I replace the SAM module. I have checked all fuses and relays replace the blinker switch it the blinkers will work when the car is not running soon as it starts they don't work. But the wiper still don't work. What could this problem? Replace the batteries well.

It sounds like you have a ground issue, here are the ground circuit wiring diagrams with a guide to help you check the connection, also you can do a CAN scan which will go over all network components. here is a video:

When you say angle sensor do you mean crankshaft or camshaft? I dont think either will cause the blinker, wipers and sunroof not to work.

Exactly God as well but I thought I would ask anyways cos I'm still trying to figure out what the problem may be I also have another question for you about the SRS light it comes on and when it does come on there's a clicking sound behind the dashboard within the dashboard and the right hand blinker when he turns left the flick is really fast so I'm thinking that's a lightbulb issue I'm not too sure what your input on it please and sometimes works for the right when the cars not going when sitting in Park only but when it goes and also when it goes into gear it doesn't work at all only the left would you be able to give me some insight on that please if you can possibly Thanks very much I wish there was a way I can buy the manual for the electrician problems and to repair the car for myself if you know any way I can do that can you please send me through a link so I can buy it cheers

Will the clock spring cause a problem like this because there's power going to it sometimes but then sometimes it doesn't work the buttons on my steering wheel and sometimes the buttons work fine so it's a real difficult one but the air conditioner is on constant blowhard and I can't change none of the settings on it neither and it's only happened since everything has happened and will happen together I've had it to 2 electricians and they said I don't know what it is they told me 500 each and now answer
