High beam and low beam lights both get their power from the same fuses. The ground for the low beam lamps comes from the headlamp dimmer switch (turn signal switch) The problem is most likely a bad headlamp dimmer switch. To test this, you can jumper a ground wire to the dark blue wire coming out of the headlamp dimmer switch. If the low beams come on, you then need to replace the turn signal switch.

Ok. This might be dumb, but where is the headlamp dimmer swith located on a 2001 chevy mailbu? Also, both of my turn signals work so does that make a differenc?

The headlamp dimmer switch is built into the turn signal switch. This switch is actually called a multi-function switch because it controls headlight dimming , turn signals, sometimes also incorporates switches for the hazard flashers and cruise control It does not matter that the turn signals both work, the circuits are separate, but still reside within the same switch assembly.
