2000 C/K cabin fan-only works on High

[GM Guy]

What all needs replaced/fixed when a C/K cooling fan only works on high?

This is on a 2000 OBS C3500 with air conditioning, so it is the fully electric panel.

I searched "resistor" in the interior section of DP and came up with these 2 links.

We had the same problem on our '04 2500HD...would only work on setting 5. It was an easy fix...only about $25 from the dealer. I'm not sure if your's is in the same spot though.
