OK, here's my prob...

along these lines.

Noticed the temp climbing in traffic yesterday. OK when underway, get home and the aux fan isn't running. I tried grounding the temp switch wire, and all I get is a clicking sound coming from the passenger firewall area. Sounds like the relay is trying to kick in, but no fan.

I did not disconnect the A/C switch in this equation. Should I have?

Also, working solo, I can't tell which relay is clicking. There are three in the area of the pass firewall, two round ones flanking a square one. Which is the likely relay?

Now, I'm off to squint at the wiring diagram some more.
