#101 of 307 1997 GMC Jimmy 4WD Hi/Lo buttons won't push in by cacyrc

Oct 23, 2007 (9:47 am)

We got a part (4wd switch) from an auto salvage yard because we thought it would fix the issue of the buttons being stuck. When we connect the part you can push the 4wd buttons in but now they do not light up as they used to. We are guessing that we just got another bad part. We also checked the fuses and they are fine. Does this sound like the problem to you too?
 
Thanks!

Are you trying to change from 4WD to 2WD when you are driving?
 
I think its safer, if you pull over, put it in neutral, and change over to 2WD or 4WD.
 
Mine jimmy's at about 150miles, 250kms, and my truck shifts from 2wd to 4wd to 4wd low perfect, I just keep replacing the trasfercase fluid every summer...its easy and so cheap to do.

#104 of 307 1995 GMC Jimmy 4x4 Engage/Disengage Trouble by scarello

I have a 1995 GMC Jimmy w/145k
 
When you engage 4WD High, while rolling in 2WD Drive, it has a brief delay and you can "Feel" and hear it engage, but when you go back to 2WD, while rolling in 4WD Drive, it seems to wind out like it's in a Low Gear and seem to hear/feel mechanical "Grinding" then almost a loud bang and it goes back into 2WD and drives normally.
 
I would almost think whatever engages or disengages the different modes is not doing so completely.
 
Any ideas?
 
Thanks everyone

#105 of 307 2001 GMC Jimmy 4x4 will not shift into 4hi by abbyteed

I have a 2001 GMC Jimmy SLS with 130,000 km. It will not shift into 4Hi, Auto4wd or 4Lo. The TCCM has been checked and it is OK, and the shifter motor is OK and the transfer case shifts... BUT... when I push any of the buttons, the lights just flash and flash for a couple of minutes, and you can feel like it is attempting to shift, but it never happens and eventually the vehicle goes back to 2Hi. I don't know what else could be the problem if it is not the transfer case, shifter motor, or TCCM.
 
Any suggestions would be greatly appreciated! Thanks in advance.

I have a 2000 jimmy with the automatic button. The check 4x4 light came on for a min. or so and went out. The wife was coming home and put it in 4 auto and was fine, when she got to a really bad roar she tried to put it into 4x4 hi but it went into 4 lo. Then it would not come out. when she got home and told me I went to check it out and it went right into 4x4 hi, then I pushed 4x4 auto and it went ito that. I pushed 4x4 hi again and it went ito lo and will not come out. What is up with this . I guess I need some help bad. thanks

#109 of 307 99 jimmy 4x4 problems by parker9

Dec 07, 2007 (9:02 am)

i have the 3 button style with 2 hi, 4 hi, and 4low. I've read all the postings in this section so i have already checked the vacuum lines and there ok , the actuator under the battery tray is working, i can hear the transfer case motor changing when i select 4 hi so i assume that is working also. but only the rear wheels are spining in the snow. any suggestions ???
