Have you checked the coding of the J255 climatronic control unit, also look at meas block 044, If you have changed the J126 air blower control unit and its still not working there may be a problem with the climatronic control unit or the refrigerant pressure and temperature sender

is there any gas in the A/C the Clito stops the blower when no gas
