#92 of 236 2000 4x4 blinking and not working, its not the switch by jasdav1 Mar 11, 2008 (11:01 am)
I have a 2000 chevrolet 1500 with the 5.3. It has the autotrac with pushbutton on the dash. Now for my problem, When I press the 4hi, Auto 4, or 4 low , the lights just blink and it will not go into 4 wheel drive. When I push 2hi the light comes right on. It will shift the transfer case into lo when I push the 4 lo button, but the front wheels do not engage and the light just blinks. I have replaced the switch and checked the ATC fuse and the 4x4 fuse. Any suggestions? Replies to this message: jbeyhi (Aug 01, 2008 10:45 am)
#93 of 236 Height of 2005 Z-71 by siregor Mar 17, 2008 (9:56 am)
I recently purchased a used 2005 Z-71. It has after market wheels and tires. The tires are 285/70-17. This truck is about 2" higher off the ground than most other trucks of similar vintage. I compared the original tires (265/70-17) diameter to the 285's and found that there is only about 1" difference. This would result in the vehicle being only 1/2" higher. Any thoughts as to why the difference in height?   Thanks   Egor

Replying to: tpruitt (Mar 22, 2008 2:46 pm) typically there are a number of components that may go bad. 1. selector switch, located inside the cab 2. differential actuator, located on the frt. diff 3. encoder motor, located on the transfer case 4. in your case vacuum module, location ?

Replying to: tpruitt (Mar 22, 2008 2:46 pm) consider this.... go to the dealer parts department ask them to pull up the parts on the comlputer part directory they think could be bad for that year 94. if they don't respond favorably ask if they could print out the exploded view of the part i have listed in the prior message. check them out one by one Replies to this message: tpruitt (Mar 23, 2008 10:54 am) justgettinby (Sep 30, 2008 4:07 pm)
