Blower Motor Controls bad? Blower Motor & FSR Replaced before.

[Clockwork]

***EDIT***
it was a freaking wire that worked its way loose somehow behind the HVAC controls pannel

Hi Guys.
I had my blower motor replaced with an OE part about 30 k kms ago. I have replaced Final Stage Resistors twice (when fan speed was not adjusting from controls yet air was still coming from system.
NOW I have a new issue.
None of the speeds work on the control panel. But the control panel lights up as normal and all buttons work, as normal and the speed goes up and down...but no fan motion occurs
I checked fuses 34,48 (A/C but just to be sure) & 64. All work.

I was removing the HVAC control unit from dashboard and when I removed the 3 wire black harness then big blue and nothing strange happened but when i unplugged the 8(ish) wire Black harness from the HVAC controller, the rear seats fans came on at mid speed, even tho their separate rear controls were set to off. Makes me wonder if there is a short or something wrong with HVAC controller

Has anyone had this hapen before during their repair and if so was it just a new HVAC control panel was required?
I'm realllllly hoping its not a Blower Motor that is required again.

Thanks for your time.
