Need 22-40 for the HVAC troubleshooting flow-chart... any way to get them?

 

I don't have soft copy of that only the hard copy. It's diagnostics for thermoswitch A. This is a simple thermal switch that closes to enable cooling fans. W/ cold engine it should be open, and w/ hot engine (199F and above) it should close. It would be easier to test for hot-closing by suspending switch in a pan of hot water and check for closing just before water boils.

good luck
