I also have a 1999 Tahoe and have trouble getting into 4HI during the big East Coast Blizzard this weekend. It finally went in and now it will not go back to 2HI. When I hit the 2HI button, I can hear the motors underneath making noise and the relays in clicking behind the dash. The 2HI lights flash a few times and simply goes back to 4HI. It will not go into 4LO either. I tried warming the transfer case area and motors with a heat gun, no luck, Pulled the fuses as suggested above, no luck. Went back out after luch and now the lights on the selector are dead; fuses was blown. As soon as I intalled the new fuse it blew.
Just dropped it off at the local Chevy Dealer and I am impatiently waiting for the call. Based on the symptoms read in this thread and what I have described on my Tahoe, does it sound like the motors were locked up and now they just seized, causing the over-current?

Speaking not as an expert, it sounds like you diagnosed the problem correctly. I'm guessing the dealer may have to scan the TCC for trouble codes to see what else, if anything, may need repair. Your Tahoe is like my '99 Tahoe, and after 10-11 years, "stuff" just wears out.
Good luck on resolving you 4WD problem.

Well the dealer told me that they need to replace the encoder module behind the dash, that was going to be approx $700, if that did not solve it, they would have to replace the encoder motor, add another $700. There is no way I could spend that just to have 4wheel drive a few times a year. I had them lock it into 2 hi, they pulled the motor and disconnected the drive shaft, so I now have a 2 wheel drive Tahoe. Set me back a couple hundred dollars.
Thanks to all the thread posting out there.
#64 of 120 Tahoe Dashboard Indicators Failure
Feb 14, 2010 (8:31 pm)
My 2003 Tahoe indicator gages on the dashboard are begining to go out. My mechanic tells me that the resistors are failing, hence the gages going out and sometimes re-setting again. I have heard that this is a more common than not problem with Chevy and GM Trucks. The repair seems to be replacing the dashboard completely - a pretty expensive option.
Any information on if this is happening generally or how it has been handled would be appreciated. Thanks,

Do a google search on replacing insturment cluster. There are companies who will repair your cluster, and it's relatively easy to do, video's available which show you how to take it out and put it back.
There's another edmunds forum on sub/tahoe with many posts on this subject.
It's not as expensive repair as you may think.
#66 of 120 Service 4wd light on
Feb 20, 2010 (6:33 pm)
I have a 2000 Chevy Tahoe and my service 4WD light comes on every time I drive my truck about 15 miles. I can switch it in and out of 4 wheel drive with just 1 push of the button and it does not make any noises when in either 2 wheel or 4 wheel drive. I had the front differential fluid changed and the light still comes on. I don't want to take it to the dealer because over the phone they have already let me know they are going to take me for a ride. Took it to Auto Zone and their computer shows no codes. Disconnected the battery and light still comes on. Can anybody help me with this problem.

On my 2003 suburban all the light for the 2wd, 4h, 4l, N lit up all at once and stayed on. I ended up taking it to the dealer and they had to reprogram the computer module for the 4x4. Have not had any problems with that since then. Has been over 3 plus years now.

I've only owned my 2004 since August and have only had the one problem with my front accuator.
Sorry I can't help.

i have a 2000 that im suspecting the culprit to be this issue. everytime i switch from 2x2 to 4x4 i hear a big clunky noise coming from the rear axle. now that i come to find out this shift on fly 4x4 isnt the same as im used to . i hope i didnt do bad damage to my truck.
Now it seems to be stuck in either 2x2 or 4x4, but the truck doesn't seem to accelerate properly. Might this be the issue? any help would be appreciated.
#70 of 120 2004 Tahoe 4x4 Transfer Woes
May 31, 2010 (1:16 pm)
We got our Tahoe about two yrs. back while living in Colorado, never took it off "AUTO" setting and maybe it engaged a dozen or so times on its own.
Then one day the tramsmission went "CLUNK" and the light went from "AUTO" to 4 wheel "HIGH" without any request from the driver. I reset the "AUTO" position on the switch and there was noise and then no lights on the control panel. The lights stayed off for 6 months and in that time we relocated to south Texas.
About three weeks ago the light for 4 wheel "HIGH came back own and I reset it for "AUTO" with no results, so, I tried 2 wheel and it came on properly. My wife drove the vehicle for about two weeks during which the lights switched from one to another and back again...during that two weeks, we had it at the dealer TWICE and they sent us away with an appointment to return at a later date...no problem..right?? WRONG ANSWER!!!!!!
On Friday 5/28 the Transfer Case errupted and the case was cracked beyond repair. The symtoms never raised a red flag with the service department who said it only need a $250 part and reprogram of the control computer.
Believe it or not it still drove normally after the explosion, albeit, with some tinking sounds at low speed. The vehicle is hospitalized at present and we do not have a prognosis and are not sure if our extended warranty will cover this repair.
The rental suv is nice and we are holding our breath...I will post additionally when the damage estimate comes in..
LESSONS LEARNED>>>>so far.
1. Never ignore the absense of an indicator light..have it checked.
2. The service department may NOT always steer you correctly.
3. The information here is more reliable than my dealerships service dept.
