I believe macdrone knows what your problem is and has the solution based on your first post. It's probably the tumbler aka ignition/starter switch; although, it could be the wiring going to the switch.
And now of course there may simply be too little power to run it. When the car is running what do you have for volts on the battery? It should be minimum 13.2 volts and not exceeding 14.2 volts.
That circuit is hot in run. That means that when you start the car and let go of the key then the circuit should be hot. That happens to be the same position you say the blower works now except it only works there before you turn it all the way to start. So that is why it seems to be the switch (or the wiring to the switch).
The hot wire goes from the ignition switch to the fuse box and when the ignition/starter switch is turned to the correct position it makes the circuit hot. It's probably the tumbler aka ignition/starter switch.
And it is a pretty simple circuit comparatively speaking; there is the fuse, a ground W1, a connector, the blower control unit and the fresh/recirculate air switch S24: ACC Power Distribution
W1 Main ground (behind instrument cluster) Behind left side of instrument cluster 235-5
X64 Connector, blower speed control/interior harness Above and rearward of brake booster
S24 Fresh/recirculated air switch Center console, above radio
