since i bought my car about 2 months ago i have been having electrical problems inside of the car. here are some electrical issues.

1. when i start my car the sometimes radio dont work so to get it to work i have to turn the headlights on or turn signals on.

2. usually just my back speakers work until i either turn my headlights on or put signals on or open the passenger door then close it then all speakers will work.

3. car gets bad radio reception when i step on the brake pedal to hard and sometimes looses signal until i step on it hard again.

4. when i turn the dome light on automatic mode so when u open the car door the light turns on. instead of it just turning on it stays on and dont turn off unless you just flip the switch to off mode. and when the dome light is on there is a buzzing/ humming either from dash or speakers.

5. Sometimes on the dash it shows that the passenger door is open even tho it isn't.

please help me cause im tired of these issues.
thanks for the help

 

well first check your dome relay by doing so switch it with something else that has the same relay for a moment and see if that fix your radio and your dome lights situation.

 

i will try that and see if it works

 

oh do have an alarm if you do disconnect the main fuse for your alarm and see if that make any difference that might malfunction on you too.
