If you have no 12v at plug [ red], then they have eliminated that and gone over to fuse box to grab it ..so, it can be anything form a bad wire to CC, to who knows what they did.. ..the trick is to see if you still have varable V at yellow ..the blower can get 12v from anywhere b/c the fan motor is ALWAYS hot..the switching for the blower is done on the ground side of the circuit
[ Switched Ground] through the regulator.
If you ground the blu wire at the regulator, you should have full fan b/c that test by-passes the reg/cc panel circuit,... that is the test for full fan/regulator,,but you want to know if you have trigger at yellow first or you are wagging the dog by the tail. No trigger at yellow= no fan , no matter what you have at fan feed...the reg needs trigger to ground the neg side of fan motor to complete 12v to fan..
