I replaced the blower switch and blower motor, but still don't have high blower.
Before that I had only low blower. I now have 3 speeds on blower but no high blower, I checked all fuses and all are good

There is a blower relay
the low three speeds go through the switch, one side of the relay and through the resistors.

For high speed, the switch causes the relay to energize and the full battery power is sent to the motor without going through the dash switch.

It's normally silver metal.
Rectangle in shape
near the blower motor under the hood.
Looks like something from the 60's
