hi guys i want to ask for some help...there are times where in our van will indicate that a door isn't closed well/locked as it will be displyed (yun indicator na malapit sa gas gauage, odometer etc...dko lam twag dun). however when i check, all the doors are shut and locked. most of the time, this happens when there are bumps on the road. another problem is regarding the horn. i removed the fuse because one time the horn just started buzzing by itself. Because of this, i think the two problems are related as both might be caused by some electrical problems/issues.

what do you think guys? Also where can i have this checked/fixed?

TY in advance!
