_Matt_ 42 Report post Posted October 13, 2010 (edited) It hasn't worked since i bought it and was just wondering what the best way to diagnose the problem is before i pull things apart I know this seems lazy on my part, but i thought the more experienced could point me in the right direction. edit: by not working i mean it sits bellow cold all the time, its just dead.

BM WORLD 1283 Report post Posted October 14, 2010 bad conections inside the cluster behind the temp gauge , faulty temp sensor on the engine? Quote Share this post Link to post Share on other sites
_Matt_ 42 Report post Posted October 14, 2010 is there an easy way to eliminate cluster connection? try to force the needle to move? Quote Share this post Link to post Share on other sites
Nobimmer 694 Report post Posted October 14, 2010 Na- don't force it... if it isn't already broken it will break. Have you pulled the cluster apart? Should be able to see if the connection is buggered. Otherwise check the sensor plug hasn't come undone and is clean before you start replacing parts.

BM WORLD 1283 Report post Posted October 14, 2010 you can short the temp gauge pin/plug to the engine block and the temp gauge should go right right up , if not start pulling the cluster out and pull the face off , check the bolt conections from the temp gauge back to the main circuit board . also check for SI batterys for corrsion etc Quote Share this post Link to post Share on other sites
