The fuse that controls my dash lights and running lights on my 2003 mazda protege 5 keeps blowing...what could the problem be?

Twist the bulbs back and forth to clean the contact surfaces on the ribbon in the dash...try it with the parking lights on....look for illumination............

need to inspect the bulbs and holder of the tail lights

bad earth , corrosion ,

if brake lights faulty could also be pedal activation switch

if no better
it may be the tail light switch at the dash

Hope this helps

One of the light fixtures has a grounded power wire. Examine all light fixtures closely for bare or grounded wires. If you find nothing, trace the wiring harness to switch paying close attention to places where the wire harness passes through holes on the body for the harness. Any contact with the steel vehicle body from a power wire has the potential to cause a short, which will blow fuses faster than you can replace them. Start with the outside tail and marker lights. Also look for broken filaments inside the bulbs, as a broken filament touching another filament or wire inside the bulb can do the same thing. Good luck.

problem with one of the flaps ,just turn vent control to screen so it blows onto screen instead,or put a clamp on the water hose

no it is not normal. bad switch on the controls

First you must cut the Dimmer wire from your stereo installation.Second, replace the 5amp or maybe the 7amp fuse that blew at the fuse panel near the LEFT foot rest.If you are certain that all the fuses check fine, then go to your MAZDA dealer and purchase a new thumbwheel dimmer control,because the rheostat has burned in your present one.Do not reconnect the dimmer control wire 2 your stereo wiring,because U don't need to.

a fuse is likely for the dash... but i would look for the relay that controls the windows as that is the likely culprit for the window issue

There are two bolts on the side of the fuse itself. Under the fuse box on each side. Unbolt those and it will come out.

try grounding the wipermotor housing.
