On my 20003 S600 my rear air conditioning is inoperable. At least the blower motor is.

When I have the front AC off, and the doors open I can hear the radiator fan speed up as I turn on the rear air conditioning, so the controls are working properly. There is just no fan. I have tried pulling the two fuses for the rear air conditioning but nothing happened. Is there a relay for the rear blower motor? If so, where.

I do have a parts car I could steal it from if the motor is simply busted, but I would also have no clue how to remove the center console in order to access it. Would I need to recharge my AC if I replace the center console blower motor? Thanks!

Before you do anything, consider this: The rear HAVC unit can be programmed such that it only works when the rear seats are occupied.

So, sit in the back (seat belt on) and try it.
If it works then, you may consider reprogramming it with DAS

When I saw your response I got really excited and tried it out! Sadly it didn't work on either side when I sat back there and buckled up. The "rest" setting also doesn't work.
