Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
I have a 2006 H3 with approx 48K miles. Recently i was getting passlock issues, so I replaced the passlock sensor. While going through the re-keying of the sensor, during the 3rd cycle, I started hearing a clicking. I found it to be what looks like one of the sensors for the 4WD. It is located under the dash, behind near the radio.
It keeps on clicking while driving. I changed to 4 high lock and then to 4 low lock without any issues, then back to 4 high and it stopped clicking. Got it back home, turned it off and back on and it started clicking again. Is that sensor bad? What does it take to replace?
