The blower has a rheostat which may be failing, but that doesn't explain why the blower can turn on with the ignition off. You might want to look at the wiring between the rheostat and the blower. Check for a burned wire.

The MCC is cable controlled, so there are no codes. But one of the cables may be routed incorrectly and the only way to verify this is to pull the unit from the dash.

If the compressor cycles a lot, it may be low on R134a.
