I keep blowing the fuse for my brake lights and rear turn signals. Every time I try to put another in it just blows. What could be causing this?

Do you have to use the brakes or signals for it to blow or does it as soon as you put it in?

Blown fuses usually indicates there is an unwanted ground causing there to be a short in the system. Check your wires going to and from your brake lights and make sure no insulation is rubbed through causing the bare wire to short on the body or chassis. Hope this helps!

Yes, a short is caused by a power supply shorting to a ground. However, I was wondering if the fuse blew before the brakes or lights were used to determine if the short is before or after the switchs. Let me know so I can better direct you where to check.
