I'm having the same problem, just checked. The fan works with a jumper in pin 2 and GND, but not pin 3 and GND. Turned on the A/C, and the fan works. Can't be sure what speed the fan works with the jumper, or the speed it works with the A/C on.
What's next, replace the radiator sensor?

Right now I'm chalking this up to the fact that I had to rewire the fan (connector was bad, so I removed it and soldered the connections). It worked well for a while, but the low-speed wiring may have failed. I'll have to wait until I get home to check it. I've got a new coolant temp sensor on the way, and I'll re-bleed when I install it. Any other ideas? |
