It sounds like there is a shorted circuit somewhere on your vehicle side that is causing the fuse to blow. The short would cause excessive power draw. It can also be that a wire is pinched on running light circuit.

You can use The Digital Multimeter with 42 inch Long Test Leads - LED Display # PT89ZR which can safely troubleshoot the vehicles electrical circuits to see where the short is. You can also test electrical components for faulty wiring and voltage.
