They're on strike, but haven't made any demands. A/C is broken, so I can't test to see if they come on with A/C. I changed the CCRM, and I changed the resistor. The high-speeds come on when it's nearing the H, but the low's never kick in. Any thoughts? And how bad is it if it frequently approaches the top?

High speed comes on ~225F. Low speed should come on ~215F.

My gauge just has an H at the top, no number read-outs. Before my engine swap & fan failure, it would stay right in the center of the gauge, maybe a degree or two over center. Now it's maybe 3 or 4 degrees below the top line on the gauge. (Angle degrees, not temp.) I don't have an overheating problem, because if I'm driving at any speed over 25, it's fine. It just cooks at idle, or a high load <40. Maybe the temp sender's just reading off?

Is it getting 12v at the fan connector when it should come on?

If you have the AC on the high speed fans should come on at idle.

The high-speeds work. I had them running on a rocker switch for the past couple of months while I tracked down a CCRM that didn't cost $200 from the stealership. The AC is smashed and isn't connected. I can try flipping it on to see if it'll send a signal to the PCM, but I'm not sure. I'll try testing all the wires & seeing where the break is.
