Sorry to thread dig.. But I would like to express MUCH thanks to OP for writing this up! Had to check it a few times to make sure I was on track .. Very easy with the guide, thanks greatly !!
Excellent Thread. Thanks heaps. My Blower refused to turn off last weekend. With this thread it was an easy fix. Just to update - I picked up an NEC 2sd1297 (same type as came out of my car, a VS Caprice) and a thermal cut-out from the local Wagner outlet in Ashfield, Sydney all for the princely sum of $12.00. I found an excellent guide to fault finding and replacing the electronics, including photos, at Fix the Fan Control Amplifier on your Infiniti Q45 or Nissan Maxima. Oh yes, I almost forgot. Holden can supply a unit for $267 plus installation Jon
Awesome Info. As at Jan 2014 the part new from the Holden dealer is $100. I bought one from the wreckers for $10. So far so good. Thanks heaps
