Today on This Old TJ: After replacing the HVAC controls did not take care of the two failed blower speeds, the blower motor resistor was the next part in line for replacement.

Short version:
See the chapters below if you're looking for something specific about this job.

Long version:
My resistor did not show any signs of over heating or melted wires. The newer model year Jeep TJ appears to be different from the earlier model Jeep TJ. Overall the process did not take very long to complete and requires minimum tools. The blower motor resistor I picked up was under $28 and came with a lifetime warranty. After replacement all fan speeds are once again working and there are no signs that the blower itself is failing.
