Help with codes
 

I am reviewing the service records of a 95' 993 C4 prior to purchase. I noticed on a bill from July some notes at the bottom of the invoice.
" Climate control codes - 0015 Rear blower temp sensor.
0024 Fresh Air flap motor, - 0043 Rear blower motor stage 1 seized right side of turbo, 0044 Rear blower motor stage 2 seized right side on turbo, Inside sensor motor signal implausible / motor seized.

The owner says he does not remember anything about the HVAC system being out of order on the car and I do not notice anything wrong. Any advice / opinions would be appreciated.
