Question about 2004 Chevrolet TrailBlazer
Replaced resister pack, but still only have high setting for the blower fan on a 2004 trailblazer
Check fuse #44 in rear fuse panel. Also did you inspect the connector that the resistor module attaches to? Sometimes the contacts or wires get burnt.

Your switch acts as a reastat which adjusts your speeds your switch is going bad so you only have the two speeds left on that reastat.. thanks Jerry

It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.
