Looks like if you can turn the fan on by (using the labels on the dwg): - Shorting across the refrigerant pressure switch's connector, X(S32)
- taking pin one of that connector X(S32/1) to ground - notice it's wire color is BR/BU.
When you first disconnect X(S32) you should see 12V at pin 1 - if not K10's coil is bad or connectors are bad
If you are energizing K10 by shorting across the X(S32) connector or taking it's pin one to ground you should see 12V at: - K10 pin1 - if not, K10 contact bad or connector problems
- both sides of R15 - if not, connector problems or R15 open
- at the fan's connector (R15 side) - if not, connector problems or R15 open

I'm not so sure I should see 12v at pin 1. If I did, when the switch closed there would be a short to ground. The other pin of s/32 is ground. Or I guess there's a substantial resistance in series with the inductor in the low speed relay?
