Maybe the fan output duct is partially blocked.
If it makes sound the same way a flute makes sound I'd look for a small opening where some of the fan air is escaping.

I see 5 VAC across the pressure switch

>Sounds like a corroded connection upstream, I'd expect 24v or 0v unless the pressure switch is a rheostat.

Actually, it's single phase. The two pole CB picks up both sides of the center-tapped pole transformer secondary 240v winding.

"adjacent".

Is the slot on the other side of the neutral line? If not you'd get zero volts to your washer.

My bad. :(

A working Triac when on & passing current should probably read a volt or so across it.

With that diagram you have to follow thru each wire over several pages to see which go to +12v. One or several wires powers the cluster.

That power supply will certainly work, 5A x 12v = 60w &...

The AC range has a 10v scale. I guess when measuring 300vac you're supposed to multiply the needle reading by 30.
The burden is on the user to make sense of the readings, but this is extreme. :( The...

If you can pull a vehicle schematic you can check if the cluster takes 12v. If so, a 12vdc wall wart transformer is a good bet. But what is the current draw?

The meter face says "10 kilo-ohms/V" so on the 10v scale you have 100K.
Really old cheapie analog voltmeters had 1k per volt & the better ones had 100k/V just before the electronic DVMs came along...
