Hello Haroon ! Have you fixed the problem yet or still clueless? I will appreciate if you let me know as I am facing the same problem and I dont want to be robbed by different technicians saying different things. Please help.

I have the same problem with my 2008 trailblazer., Temp gage not working and A/C not working, Intermittent problem, any one have a fix? Thanks Charlie

Any decently equipped auto repair shop can use a *professional quality scanner* set to functional test and check the signal to ALL GAUGES in the instrument cluster.. Then each gauge can be tested with the scanner to see if it is responding accordingly .. Im talking about a REAL automobile scanner that probably cost 8k $ and up .. NOT some lap top or code reader! .. I have performed this test many times and had NO problem determining the culprit .. It is either the temperature sensor, wiring or the gauge .. Period!
