What are the troubleshooting steps you recommend for a condenser fan that doesnt

If you truly wish to troubleshoot this on your own, have a diagnostic tool that can monitor system components and proper electrical testing equipment, then I would recommend investing in the modest cost of shop manual access, as there is too much to suggest here. Circuit protection would be available in your owners manual, with a diagram to show you what fuse and relay goes where. Hint: if you bang on the fan and it starts working, you do not have a relay problem. Gut feeling is that you have a motor concern, wiring concern, or something localized. Do not just throw parts at it though, testing is needed. Lastly: yes, you must remove the condenser and fan as an assembly, so refrigerant handling is required.
