Anyone that does not have the ' manual' type one ( like my 1980 240d ) MB AC feels your pain...
It really sounds like a power to the blower problem first.. with or without heat or air it seems it should still blow some air... (?).

Agreed. I wrestled with my climate control for months. It sounds like the logical thing would be to test getting power to/from the blower first. If you get nothing, the relay could be bad.
Did you remember to connect 12v directly to the blower motor, just to make sure it spins freely? Even new stuff can be defective (ask me how I know). Also, check that the aux pump works too, with direct power.
