The headlight switch has a rheostat built into it to dim your dash lights, it may have shorted out. As soon as you turn on the switch this rheostat comes into play and is probably whats blowing the fuse. I think if you replace the headlight switch, it will solve your problems.

My 2005 matrix keeps blowing 15amp rear running light fuse every time light get turned on all other lights work fine.whats causing this?


fuses blow because of dead shorts or excess current draw
to blow a 15 amp fuse indicates a dead short
by disconnecting the rear lights , the problem is in something else you have replaced
could be a problem in the head light wiring

My 2002 ford ranger running lights and instrument panel dont work


12V power passes through 15A fuse 33 (the one that keeps blowing?) in the battery junction box and on to the main light switch. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the park filaments of the dual park/turn lamps. These lights remain on when the headlight switch is turned to HEAD.

The main light switch gets its 12V input from 7.5A fuse 11 in the central junction box and the same 15A fuse (33) identified above. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the instrument panel dimming module and module output is applied to the panel illuminating lamps.These lights remain on when the headlight switch is turned to HEAD.

The input to fuse 33 is hot all the time so should read 12V. If you read 12V at the TAN/WHT connection with the fuse out, something is definitely not right. I'm sure you have noted that the fuse is common to the non-functioning circuits you mentioned.

you may have the wrong wires hooked into the switch. try testing the wires with an ohm meter and making sure they are both the positive wires. always disconnect the negative battery terminal before installing any electrical devices

How do i replace light bubs on the dash panel and door button, do i pull the button up or what to replace the light bubs.


These bulbs last a long time and if they'er all out you might find the running lights ( taillights arn't working too. ( blown fuse) the panel lights are on a separte fuse but they run off of the tailight fuse. the tailights are really all the lights that come on with the headlight switch except the headlights themselfs. Then that circuit entergizes the panel lights thea light the dash gauges the door panels switches the any console lights the car can have. the dome circuit is another fuse that lights the floor and dome ( if their is one) and any landou lights (piller)
sometimes this fuse is removed or blow and the dash lights don't work, Or sometimes just a few. The cluster can be removed but not all of the bulbs can be bought at the parts store as the lights are to be replaced by rebuilding the cluster and can't be serviced. Agin some of the door switches are made this way also and you have to replace the switch to get a good light in them.

Interior dash out, tail lights and running light out, is this a fuse? where is it? Signals and brake lights work but blow fuses when it rains


No interior dash lights and no tail lights on a GM usually means it's time for a new headlight switch. To check the fuse, it's in the middle of the fuse box marked instrument cluster. If the fuse is good, buy the switch. Lights blowing fuses means you either have a bare wire running down the driver's side of the truck or up into the tail light assemblies. There is also a plug in under the box on the driver's side near the bumper that may be getting wet. Hope this helps.

If good
Did you check the dimmer on the head light switch Pull out to see if you have power on cable color orange / blue. (Pin 9)
If this is good
Pull cluster out to see if you have power on plug pin 3 in instrument cluster this there..
If you have power
