Resolved, as in the problem never came back? Or as in you found a problem?
We had the exact same problem. The temps started climbing on a recent trip, so we pulled over to find that the fan was free-wheeling (clutch not engaged) and the engine bay was very hot. While looking it over, the fan kicked on. We didn’t have a problem the rest of the trip. Back at home, we did a little troubleshooting with the low-speed fan relay by taking an old relay and bending pin 85 out to force the fan on, and it worked. We replaced the relay anyway with a new spare from Prevost and went out for a test drive. The fan worked fine, but the speedo stoped working on the way out. We pulled into a parking lot and checked for blown breakers, which there were none. Then on the way back, the tach stopped working too. There was no warning light on the dash.
After dinner, we checked again and they were both still inop. The next morning, the tach works but the speedo does not. These are the VDO gauges with the analog odometer.
(Now that I’m thinking about it again, I wonder if it was the high speed relay that caused the problem. If the high speed relay was inop, would that disengage the fan completely when it goes to high, or would it still stay in low speed?)
