Blower stopped working

[A8 Owner]

Hi all, had a problem with no blower for ages as some of you know. Possibly due to the water drains under blower keep getting blocked and filling that area full of water.
Well during last yr A8 meet, had car put on a vcd, came up with heater error (blower).
Lucky enough Neil had a spare one in his unit, got steve to pick that up for me. After all this rain we have had, i have got fed up with putting pump in there, to keep draining the water out of front. So yesterday it went into the garage to be replaced. Blower to be swappe,d and the drain holes fully cleared and Modded.

Call today Blower was tested before fitted, works fine, Drain holes above gearbox cleared, ends cuts. Metal piping secured, and added to the end, to make drain longer and clear sound proofing, plus easyer to clean out if ever needed.

Problem is, blower still not working in car gggggrrrrrr. Any ideas???? next port of call is going to be the resistor blower control(hedgehog) as that could of been in the water also. Other than climate control unit? Unit lights up just no blower
Is the flap solinoid(bad spelling) in that front area also?
