Hey guys. This is my first post. My alarm is going off randomly several times a day. When I toto turn it off the radio is also playing. I've noticed ,some people have had similar problems. Most of them being caused byg water leaks shorts out certain circuits. I however have not found any leaks inside or outside the car. Any suggestions? Thanks

 

check the door switch.

 

When asking a question, it is always best if you provide year and model, not all H3s are identical.

If you have an aftermarket alarm, then you have to look at that as the problem and make sure it is functioning correctly before looking for a separate truck issue.
