very simple fix!
Try dropping the glove box door to get access. You should at least be able to see it at that point. The resistor is just two bolts and a electrical connector after that. The hard part is getting to it.
need help changing the belts on my Chevy trailblazer lt 2003
I recently had to change mine...about a $25 fix. Kind of a pain to do but not bad. The blow motor resistor is behind the glove box. well i have a 2003 Chevy trailblazer ext but i assume they are the same. just empty the glove box...and it kind of forward and exposes the parts behind it. mine was to the left. hope this helps!
How do you change the spark plugs on a 2002 chavy trailblazer
To change the blower motor resistor on a 1994 Chevy Caprice, first disconnect the negative battery cable to ensure safety. Locate the blower motor resistor, typically found near the blower motor under the dashboard on the passenger side. Remove the screws securing the resistor, disconnect the electrical connector, and replace it with the new resistor. Finally, reassemble everything and reconnect the battery.
resistor card is under the glovebox. Remove glovebox door. Should be 2 screws I think holding resistor card in place.
