Hello everyone, I am new to the board, and have looked for a similar problem as mine, but can not find one. I have a 2005 Z 71, with push button, 4WD, and the "auto" mode. I drive in 2wd, 30 minutes, 75mph, each way to work. Tranny works fine (with chevy's normal rough shifting) The other day I noticed the red light next to "neutral" was on instead of the amber light next to 2 Hi. The truck was running fine, and when I pushed the 2wd button, amber flashed for a few seconds, and went off. I pulled over, shut off the motor, restarted, and it apperantly reset. I thought life was good. Now I have noticed the red light on three more times, and it doesn't reset by simply restarting. It is very random when it is on, or off.   Any simmilar stories or advice?

#51 of 236 2004 GMC Sierra 2500 4x4 by boso56 Dec 15, 2007 (9:12 am)
I recently purchased an 04 GMC Sierra 2500 that was rolled over, after replacing the roof and other body damage (no damage to the front, rear or under carriage) I tried to engage the 4 wheel drive, the blinking lights tells me that it is engaged in 4 wheel drive. I hear it engaging in the transfer case, but the front axles do not engage. I purchased an actuator and installed it. It did not make any difference. On the highway it runs perfectly and quietly. Can you offer any suggestions on this matter? Replies to this message: bruce48532 (Dec 15, 2007 9:29 am) conclutcha (Dec 27, 2007 5:29 pm) bruce48532 (Dec 28, 2007 7:00 am)

Replying to: boso56 (Dec 15, 2007 9:12 am) The transfer case actuator that engages the 4wd is working? You replaced the actuator on the front differental housing? There are (2) actuators!   The blinking light should go from blinking to solid, I assume that is what is happening?   Did you reset the computer defalt after installing the new acturator? If not try that! (3) quick on and off turns of the ignition switch, then start it. Replies to this message: conclutcha (Dec 27, 2007 5:29 pm) bruce48532 (Dec 28, 2007 7:00 am)

I have a 2005 Silverado 1500 ext. cab with 36500 miles and after adding on to my 7 inch lift with a 3 inch body lift and new Radflo shocks all the way around, I started getting phantom warning lights lighting up like a Christmas tree. My abs, brake, security system lights go off randomly and my radio shuts off and turns back on. I also get the service 4 wheel drive and service brake system intermittently as well.   Besides the 4wd Service light, has anyone experienced this and have a suggested fix? I've tried driving with an onboard computer to pull any DTC's but no I have had no luck, it says everything is working as expected and there is nothing to clear. I even tried unhooking the battery overnight hoping a truck ferry would come by and make all my troubles go away   As for the 4wd / AutoTrac I pulled the switch from the dash and did not see any cracks in the solder and hooked it up to a multimeter and all is good. Would it still be a good idea to buy the new switch? I hear the transfer case motor click but it does not engage and stays on 2wd. I am able to get it to go into auto and 4wd at times so I'm leaning towards the transfer case motor. Any other suggestions? I tried hitting it lightly with a hammer as possibly the motor could have been ceased. When it's in 4wd or auto it performs normally. I was going to go buy a new motor and replace it myself but if there are any other suggestions, i'd like to save myself the 533 bux and time doing it. GM keeps telling me it's a known issue and it's either the switch or the motor and quoted around 1500.00 for all the work and testing. WTF! And i'm now over 36000 miles and out of warranty.   If anyone has any suggestions, please let me know! Thanks!

Replying to: conclutcha (Dec 27, 2007 5:29 pm) One is located on the front differental housing, this is the easy one to replace. The second one is located the transfer case, (Transfer Case Encoder Motor) this one you must drop the front drive shaft to replace.   http://stores.channeladvisor.com/Auto-Parts-Direct-To-You/GMC/Sierra%201500%2c25- 00%2c3500/
