Electric problems with 2008 quest

[chagousa]

Hello,
Just want to see if anybody got these kinds of problems and maybe give me a solution.

It all started with the back up sensor (beep). It started to beep out of control, there were no things in sight and it was beeping. I had to turn it off with the button and then I decided to turn it on again and now it's working.
Then my radio had no sound, shut off the engine one day and the next day I went to use the car and my radio had no sound. My aux port worked so I was able to use my phone with it, but no radio.
One day all of the sudden it started to work again.

Now it's my side door, it will no open with the inside button or with the key button. It will open manually or with the door button. With all the other buttons it just clicks like it's doing something but will not open. I'm expecting it to work any time now and then get another anomaly.

Any ideas? thanks

These sound like electrical issues. Check fuses. You may need to replace.
