#45 of 84 Re: 2000 ZR2 4WD problem [aaronj8] by beyondtime024 Dec 07, 2007 (4:21 pm)
Replying to: aaronj8 (Oct 22, 2007 7:20 am) Don't know if it helps, but I just had the same problem except none of the lights were on!! I took the dash completely out to find out it was a wire had broke going into the harness!!! I just snipped the other side and now it works fine!!! I also had a couple wires that were pulled out of the harness just far enough that my fuel gauge and my temp gauge would not work so i just took a screwdriver and pushed the wires in just a ittle to were they were working!!! Hope this helps!!!

Replying to: posblazer (Dec 06, 2007 5:45 pm) Can you here transfer case motor trying to shift, if so then it could be inside the case its self, this is the problem I have now. I can here the motor trying to shift into 4Hi but it would not go, $200 new motor and it still would not shift. I found you should be able to remove case shift motor and you can shift it with a wench with little effort,if all is in good working order in my case it dose not! So i will be removing that part next.the button tells your 4wd controller what you want it check to see if the motor dose what it is told if it dose not move it tells you that nothing is happing.the hole thing is a pain in the...., when it don't work.

Replying to: roper77 (Dec 10, 2007 8:42 am) Need to know if you can here, transfer case motor trying to shift ,you should here a noise right under the center console . there is a drive motor that is turned on by the dash switch, the clicking you here on the passenger side is a relay that powers the motor. I think if you can here the clicking that the dash switch is not the problem. if the relay is good then you should get power to motor on the t.c. I found the motor to the T.C. was not that hard to change About a 40 min job. remove front driveshaft {4 bolts}.then you unplug motor and it comes off with [3 bolts]. Then you take that to local auto parts to match , because there is three different motors and nobody witch one you have. with motor off you can shift T.C. with a wrench, there is four positions 2hi 4hi N 4l you will have to shift to 2hi to install new motor, if you cant shift you can try to move rear wheels to line up gears, or you could have T.C. internal damage.hope this helps.M.C.

Replying to: mcassel4 (Dec 13, 2007 6:30 pm) Thanks and yes motor is working I actually found the problem and fixed it a few minutes ago. I started with the actuator under the battery (actuator was in good shape) checked all the vacuum line going to vacuum switch under hood seal (those were also in good shape). Then I had a friend hold the elec. switch on the front differential pulled out the switch tried to put in 4 wheel same thing it just blinked compressed the ball on the switch and the light stayed lit so we went back to see if the actuator was actually moving and no so we went back to vacuum switch under the hood seal ordered the part from GM (they call it a valve) put the part in and it worked. $50.00 for that I brought back the actuator which I didn't need that was $59.00. Hope this helps you or anyone else. Replies to this message: chevyride22 (Feb 23, 2008 9:37 am)

have 2003 blazer 4x4, no major problems, except bad gas mileage, was driving on ice decided to switch into 4 wheel drive hi, pushed button, it is 4x4 on the fly right? running 35 mph, pushed 4x4, got funny grinding sound, acted like didnt want to go anywhere, grinding, loud.. under blazer, so when heard the sound, pushed in rear wheel 2x4 and still had sound, slowed down to 15 mph, and pushed in 4x4 low, still had the grinding sound, then pushed in normal rear wheel drive, and must have hit a bump but felt a tug of the vehicle and a loud bang, and then it started driving fine again, needless to say, wondering why it happened and what it might have been, haven't used 4x4 since...could it have been frozen?, it was 15 degrees that day..took it in about 4 months ago to jiffy lube and they changed the rear differential fluid...could it have been something they did? thank you in advance Replies to this message: mcassel4 (Dec 25, 2007 4:25 pm) charlie_a (Dec 25, 2007 5:23 pm)

Replying to: jeremys26 (Dec 21, 2007 8:01 pm) you should try the 4x4 again , well in park,it should shift,and not grind because your not moving, if it dose shift, then try to drive if you here noise than you got trouble. The rear differential drive all the time two or four wheel drive, so if it was in that area you would have know it long before now. you could have lost your front drive shaft or you have problem in you transfer case.hope this helps.

#53 of 84 95 Blazer LT 4x4 not working by charlie_a Dec 25, 2007 (5:23 pm)
Replying to: mcassel4 (Dec 25, 2007 4:25 pm) ok my 95 Blazer LT has 4WD but when i push the button on the dash for 4WD it lights up but it dont feel like its in 4WD and its not. What may be wrong and how would i fix it? im thinking maybe the vaccume sensor may be bad...   Also i would like to raise it up a bit but since the leaf springs are under the axle its more dificult. all i need is some sugestions on the cheeper better stuff to get to get the height up the most.   Thanks, Charlie Armstrong
#54 of 84 Extended by charlie_a Dec 27, 2007 (9:52 pm)
