Hi Folks,

My radiator fan won't kick on, and I'd love to hear thoughts about
diagnosing and fixing it. Here's what I know:
    -30 amp fuse for the fan is intact.
    -I tried the Ken Wilford trick of placing a jumper wire between the
terminals at the temp sensing switch behind the lower grill, and got
nothing. There is 13 volts present there, though, when the van is running.
    -inspected the large resistor behind the drivers side headlight.
Visually it seems ok; when I had to replace one before it had cracked open.
    -perhaps unrelated, but the dash blower motor is down, too. I found that
the fuse for that had blown, and a replacement blew immediately. The blower
had been noisy and reluctant for a while, so I'm guessing it finally seized.
But maybe there's a shared relay that got harmed in the process?

Thanks in advance, and I hope you're all well.
