Old thread, but no one can say I didn't search!!!
I've having a similar problem.
When I did the paper-clip check, only the high-speed fan came on.
With the car running, turning on the A/C DID make the low-speed fan come on.
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? |
