Fan doesn't work on '97 Blazer
A year ago I replaced a relay and got my fan to work on all four speeds:

That lasted for a while and eventually my highest fan speed went out again. It did it in summer and I hadn't charged the AC so I didn't fool with fixing it and just rolled the windows down.
With cooler temperatures, I'm now faced with no fan at any speed. How do I troubleshoot this issue?

Disconnect the high blower relay, Jumper the purple wire to the red wire in the relay socket. Blower must come on high speed. Post your results.
