Every-time my car goes to dealer it comes back with no alarm and it sometimes takes a few days till the remote on the visor works again!

This time the alarm came back for a few days and now is not arming again.
I saw somewere it might be the sensor on the hood latch..will look at that today but I noticed yesterday the fuel door is not locking with the doors!

I have in the past opened up a few covers under the hood and wiggled a few relays and it worked. If I knew exactly what relay is responsible, perhaps I can get this worked out!

thanks

opened the hood and let it close hard and all is good!
theres no sign of any sort of switch and my guess is its part of the latch
