Default fan relay

Trying to get my ac fan switch to go on high speed. 75 vett. Inline fuse good, changed resistor and changed relay. First three speeds work not the highest.
I took the cover off of relay left the wires attached push down on contact point and the high speed worked. Any ideas? Could new relay be no good?

The blue wire at the relay needs to be hot when the fan is on high AND the relay case needs to be grounded.
