2000 A-6 2.8l

The heater blows luke warm air regardless of temperature setting, Im getting these codes;

01809 actuating motor for temperature flap, left (v158)
41-00 blocked or no voltage

00710 defroster flap positioning motor (v107)
41-10 blocked or no voltage-intermittent

01810 actuating motor for temperature flap, right (v159)
41-00 blocked or no voltage

01272 positioning motor for central flap (v70)
41-10 blocked or no voltage-intermittent

01274 air flow flap positioning motor (v71)
41-10 blocked or no voltage-intermittent

Any help would be appreciated, could it be as simple as a fuse?

Also, can anyone explain the codes, like what does the 41-00 mean and the (v158), thanks, just curious
