In this video I have a look at a 2013 Chevy 1500 that came in with a customer complaint of no 4x4, the service 4wd light on and a C0306 stored in the transfer case control module. Let's have a look at see what the problem is. -Enjoy!

Love that you actually did a full diagnosis rather than throw a part at it. Outstanding explanation and walk thru of the inner workings of the whole circuit and process. Great example of going the extra mile and showing the full scan results, illustrating the circuit and talking it thru along with service bulletin. Haven't seen your stuff before, but will definitely subscribe follow and like. Thanks for creating the video. I'm always looking for great repair and diagnostic videos for my Silverado which I've spent a small fortune on in repairs over the years. Keep up the great work!

Thanks for the video. I have a 2007 avalanche with 190,000 miles. The dash is going haywire intermittently and saying service 4wd. I think that its the ground or the actuator. Thanks for some insight. You are definitely a great mechanic, only wish I could find one like you around me in NJ. But until then Ill need to be a hands on owner. Thanks again and keep up the good work.👍

@peteloomis8456 8 месяцев назад

Did you ever find out what the problem is ? My 09 Silverado 1500 I replaced the front differential actuator and the 4x4 started working again then after a couple weeks the lights on the dial weren't lighting up so I replaced the shift dial because it seemed loose and the trucks got 200+ thousand miles on it and then the lights came back on for the dial and it would shift from 2x4 to 4x4 then after a couple weeks again no power to the shift dial with no lights on the dial . So I replaced the transfer case actuator and now I get this big red N at the far right of the dial but that's it . I checked all the fuses under the fuse box under the hood and everything checked out good with no blown fuses at all . I had read that I'm supposed to put the transfer case in neutral before bolting on the new actuator but that doesn't make sense being most of the time when the transfer case actuator goes bad the trucks in 2wd and when I bought the new actuator there were no instructions at all saying anything about this . I've checked all the grounds and cleaned the wires going to the frame and other locations and used anti seize on them once tightened then sprayed paint on them to help seal it more and still nothing . The pins in the wire harness looked good no corrosion but I can't tell if those pins got pushed back like he was saying in the video and unfortunately I can't do a probe with my fluke to do continuity tests on the pins because GM made the pins so small I can't get my test pins for my Fluke to get into the harness pins to do the test . The wiring on these trucks is absolutely piss poor as far as how small the wires are that get brittle and crack in the insulation and cause all kinds of problems not to mention all of the body modules that these trucks have that do go bad and cause issues as well .

@michaeltretina 8 месяцев назад

The best place to start is checking the grounds. There's one under the driver. And then there's one on the firewall in front of the passenger. That ground has a mega fuse, a plastic cover covers it. I've taken that off and sanded down to bare metal. My gauges started working properly after that. It's been awhile and the issue hasn't resurfaced. Good luck. Let me know
