hi fellas.
ive got an R32 with same problem, thanks to google i stumbled on this thread and ive noticed that some people are sticking resistors in to trick the control unit into thinking its 20+ degrees inside the car. i think i may have a better solution and thought id share.
so these are the sensor charateristics:

i found these 2.2kohm thermistors on ebay for 5 bucks:
GA93521 2322 640 63222. Vishay BC Components Thermistor , NTC 2.2K 5%
http://www.ebay.com.au/itm/GA93521-2322-640-63222-Vishay-BC-Components-Thermistor-NTC-2-2K-5-/141252970692?pt=AU_B_I_Electrical_Test_Equipment&hash=item20e35548c4
so theyre 2.2k ohm @ 25deg C
according to the skyline manual we need 2.65k ohm @25deg C so they should be in the ballpark.
dunno if this helps anyone, but information is valuable and sharing is caring.
