I have found out that usually the two ground wires that are attached to the frame right under the front of the driver’s door is the culprit that causes the 4wd selector switch in the dash to go bad. Chevy had the bright idea of applying the undercoating and/or not cleaning the point of contact of the ground wires before they bolted them to the frame therefore overtime moisture, dirt and corrosion affects the contacts of the threads of the bolts which are the only source of ground the two sets of wires have. There are 2 things you will need to do. First you will need to take the bolts out and use a wire brush to clean down to the metal of the frame as well as the bold threads and ends of the wire attachments and then reattach the ground wires to the frame (time to complete – less than 5 minutes). Second you will need to replace the 4wd selector switch in the dash. You can purchase this online from Amazon (Dorman 901-062 4-wheel drive switch for $31.15 – no tax or shipping and handling). To replace, gently pull the outer trim of the dash out by using just your fingers. You do not need to completely remove it, just pull it out far enough so that you can pull the old switch out of it slot. Then unplug the two plugins located in the back of the switch. Plug them into the new switch and push the switch back into the slot and then push the trim back into place (time to complete – less than 5 minutes). This should take care of your problem. Most often, people make the mistake of just switching out the dash switch and when that does not correct the problem they then replace the more expensive and time consuming actuator motor and location indicator on the transfer case that does not need to be replaced. I should point out that when the Service 4WD light comes on, there are no codes that show up on the code readers which is awful strange in its self. I hope this helps everyone with this problem because I sure wish I knew this before my many costly and time consuming trips to multiple repair shops including the dealer and none of them were able to successfully repair the problem. It sure seems like Chevy could release a repair bulletin so that everyone could fix Chevy’s blunder. I bought my 2005 Silverado new in September of 2005 and this has been the only major problem I have every had with this truck with the exception of the check engine light that came on this past spring and the error code was P0446, which was the Vapor Canister Purge Valve. They have since come out with a new conversion kit that cost close to $100.00 and is very time consuming to replace. I highly recommend that you can purchase the original equipment part from Amazon – ACDelco 214-2147 OE Service Vapor Canister Purge Valve for $16.36. You will have to cut the vent tubing right at the old canister and use a 2 inch long piece of vacuum tubing the next size up to attach the new canister because the original tubing is hard and cannot be stretched to remove on to reinstall the new part. The canister is located at the back of the gas tank and can be accessed without having to even jack up the truck. It clips right onto the back of the gas tank and has one plug in going into it (time to complete – less than 5 minutes). Best wishes, Mike Gilbert, St. Joseph, MO

is their any body out there that can tell me how the 4x4 system travels direction wise when it leaves the switch on the dash. When I turn the ignition on allthe lights come on then they go off. You can push any button but nothing happens.

I didn't see this issue posted. My 4wd must stay in Auto 4WD. If I put it in 2H it goes thru the gears and when it hits 4th gear it drops to neutral. I am unable to drive in anything other than Auto 4WD. The last time I used the 4WD function was approximately 5 months ago and I don't recall putting it in Auto 4WD. I have very little call for the 4WD but I like knowing I have it. I recently went from NM to KS without realizing it was in auto 4WD. That was when I found that
the 2H wasn't working. Any ideas? I am unable to locate the ATC fuse that one message discussed. Not even sure this would fix the problem

I am experiencing an absolutely identical problem (with an identical truck) to yours (mine has 80K miles). I am therefore keenly interested in what you may have found out. The local chevy dealer has suggested over the phone that my transfer case had been run without oil perhaps, and that simply was NOT the case, it is full of clean oil with no burned smell or other signs of neglect. Now he wants me to bring the truck into the shop and start emptying my pockets so to speak $75/hr.
Can anyone help me out with advice?

Did you do as I suggested? Did you look at your ATC fuse? That was the problem I had, so I just replaced the fuse, And it's working now. The ATC fuse is located under the hood of the truck in the fuse box. to locate the fuse look on the legend on the back of the cover, and it will tell you the exacted one. Should be a 20 Amp fuse, if I remember right.

There is no fuse marked ATC in any of the 3 fuse blocks (underhood, center, & instrument panel). There is a 25A 4wd fuse in instrument panel block, it is fine.

#394 of 396 DOING BATTLE WITH SIRIUS
Nov 17, 2013 (9:49 am)
My 6 month trial subscription ended on October 31st, and for the better part of 2 weeks, I have tried, unsuccessfully, to renew the subscription because of an array of total idiots who answer the phones for XM/Sirius Radio Services. Luckily this was just on the phone, so I could either lay in my hospital bed or sit in my recliner while talking. If I had to stand or take any other physical position, I would have given up and done without the services.
It all started a few days before the end of October. I called Sirius to extend my subscription for "music channels only" (I don't listen to sports or news on satellite radio) and for "traffic" and "weather" services. I use weather more than traffic, but the forecast and weather maps I can access in the Mercedes show weather fronts, wind speeds and direction, rainfall and severity, storms, lightning, etc., and the info provided is extremely accurate, not to mention picturesque! Sorry for digressing. The first 8 idiots I spoke with on the phone (yes, 8 times I called to get this completed) over the 2 week period said I could subscribe to "music only" and "traffic", but that my radio and internal computer in the car could not support "weather" data! Now remember, for 6 months, I was able to easily access traffic and weather as well as all channels. Now, I guess my radio (Harman/Karmin) just won't accept the data they would send for the weather maps and forecasts!!! I state to them all, "YOU ARE NUTS!" Then, they want to charge me an activation fee on top of that.
After 8+ attempts, I decided to surrender and not bother with Sirius or their services - let's face it, doing without satellite radio and weather and traffic is not the end of the world. But when I was up at the Mercedes Dealership yesterday, they told me the E, S, CLS, and 95% of their cars support weather from Sirius. So, I tell myself, "...what the heck", and I try again this morning. I had to call them 4 more times until I finally got them to transfer me to a supervisor who spoke the King's Language perfectly. I explained the situation to him, the fact that I had been a customer for over 9 years, and that everyone I talked to at their company had no idea what I was talking about. He apologized, looked up my account, and told me that my car could accept the "data" plan they offered which includes traffic, weather, stocks, gasoline prices within 50 miles, etc. I took a deep breath and thanked him.
So, I signed up for "music only", "traffic", and "weather" through their data plan for 1 year at a cost of $229.00 with 3 months free and no activation fee. That's $15.27 a month for 15 months. At full price for the plans, it would have been closer to $350.00 a year.
I know Sirius subcontracts their phone services to some other country, but at least their supervisors are located here in the U.S.A. You would think that a "monopoly" company (no other competitors for satellite radio services) that sells a service for music and other data in the current business climate whereby they actually compete with AM/FM HD radio stations, iHeart, Pandora, and now even Apple internet radio, Bluetooth connectivity to smart phones, MP3, iPods, not to mention CD/DVD 5.1 surround sound, to name a few, would do almost anything to maintain a positive client relationship - not to mention subscription renewal process!
Why should it take a customer almost 3 weeks and over 12 phone calls to finally get to speak with someone who knows what he/she is talking about? I wonder how long XM/Sirius will be able to continue selling services with their current approach to customer service and consumer relations?

I was wondering if you have fixed this problem? My 2006 chevy is doing the identical thing. Please let me know if you have found a solution to this problem
