Stealership ?'s please help ASAP

[Planohummer]

Oversize tires and/or different wheel offset can create the need to back up, but can also be caused by worn out shift fork. Ask the dealer to show you where you authorized the $99 check out fee when you dropped off your vehicle. If you did, pay it. If you didn't, don't. Almost all the extended warranties(even GM ones) have certain exclusions. Can't speak for yours specifically.
Wind noise and bulb are easy fixes(see other threads) you can do yourself. If you've got oversize tires/wheels, put stock back on before taking back to dealer.

i dont have oversize tires on it yet, they're stock. i wanted to get all of the issues documented and fixed before i put the tires on, which should be this week. FYI, i did read the manual, and it actually does say that sometimes you need to back up 25 feet to disengage 4hi-lock. i thought the stealership was BSing me on that one. who woulda thunk it?

Itis not required to back up, but it will help the truck go back into the 4 open quicker. works on Fords and dodges too. Loaners are a courtesey for the most part. If your vehicle is required to be in over night due to repairs, then GM will provide a loaner. If it is overnight waiting on parts, they do not. Want a loaner from a dealer, be nice when you go in and promise/give good surveys. The service writers get grief from all sides, they can be extremely helpful to you if they are on your side. Although it seems petty to charge to fix little annoyances not covered by the warrantt, someone has to pay the mechanics. Sorry for the rant, but I hear it all day.

thanks for the info marinehawk, good find with the search!

my point is, when i shift out of 4hi-lock into 4hi, the button blinks on 4hi-lock and then the 4hi button goes on and stays solid. if the gauges, lights, buttons...whatever, tell me i'm in 4hi and im really in 4hi-lock, then that is a problem. that should not happen. the only way im going to know if im still in 4hi lock is to turn and listen to the noises from underneath my truck, then back up 25 feet and try again. the stupid button should be able to tell me if it shifted between hi and hilock.

I doubt this will work, but my 03 Sierra, which had the same electro-transfer case shifter thingy, twice would not shift out of 2WD-Hi into 4WD-Hi (light would flicker and nothing would happen). I realize this is different than your situation because it did what it said (not shift), but just in case: I simply disconnected the battery for a few seconds and reconnected it. Then, bingo, it would work fine for nine months or so.

[hummer74]

it is the gmpp extended warranty with the major guard coverage. i think its the best you can get.

[Planohummer]

major guard covers pretty much all mechanical components, and yes it's arguably the best coverage you can get on a pre-owned vehicle bought from an individual. Squeaks, rattles, water and wind leaks, batteries, bulbs, wear items, non-functional trim items are not covered--pretty much
everything else is. The warranty(gmpp) will typically provide a rental reimbursement IF the repair is disabling AND it takes more than 2 hrs to repair AND the vehicle can't be fixed in a day.

This isn't as bizarre as it sounds... I will say that i've never seen this problem on H2s or H3s, but H1s have the same problem - even brand new 06 Alphas. You pull the lever to 4 high, but the TC lock light wont go off. Sometimes you have to repeat the forward and reverse routine several times. I have seen both H2s and H3s 'pop' into place in about 10 feet after the lights indicating they've been in 4 high. I'm always make sure I hear the clicking sound underneath before I gun it -- because it'll give you a pretty good jolt when it does engage. The noise is stress on the system -- 4high lock isn't made for dry surfaces with plenty of traction. Have you noticed a slight burning smell as well? So, the dealer was right and wrong. Should you need to reverse an H3 to get out of 4high lock? No. Does it help a sticky system sometimes? Yes. Do you get 'stuck' in 4 high lock everytime you use it?

well, i used it in the icestorm in dallas on friday, when i got to work i took it out of 4hi-lock, or so i thought, it stayed in 4hi-lock until i got home. no it didnt smell anything. i noticed it didnt shift out of 4hi-lock immediately leaving work. after i got home, i decided to take it to the dealership because this had never happened before. i backed out of my driveway, then put it in drive and drove off. thats when i noticed it was in regular 4hi. drove to the dealership, and just before i pulled in, i put it in 4hi-lock and then tried to take it out again, just to see if it was still doing it. sure enough, it wouldn't come out of 4hi-lock. i guess im just sort of confused, ive used 4 hi lock before and it had never done this. now it does. i just figured something was wrong because it had never done it before. the manual does say that you may have to back up 25 feet to disengage, i just found it odd that all of a sudden my truck is now requiring it.

I'm not sure how far north you were during the 'ice storm' but a lot of it was just a light coating of snow. As long as you have substantial traction, 4 high open is just fine. In all honesty, 4 high can get you 95% 4 high lock will get you...I always caution folks about 4 high lock because their salesperson may say "just throw it on if its snowing or raining...it gives you more traction"...but when you have traction, that can really mess up your transfer case...who knows if there's anything wrong...I asked about the smell because sometimes you get a slight burning smell when the transfer case/4wd system is under a lot of stress. If i had to guess -- it would be that the 4 high lock system was over-run in the recent weather, and now exhibits behavior of older 4wd systems...I'm not exactly sure on the exact mechanics, others here are...I just know that i've seen MANY 4wd systems need to go in reverse to un-engage, but not H2s...

[hummer74]

i forgot to add, last time i had the truck in, i asked them to replace the battery with an optima battery. they told they couldn't, that it wouldn't fit in the h2. i KNOW some of you running them, did you have to modify the engine compartment to make it fit?

[Ed G.]

If you drive around on concrete, in hi-lock, you may need to back-up several feet to disengage. Driving on cocrete in anything but 4 hi will cause problems, it's not built for it.

Most warranty's do not cover wind noise,they are meant for mechanical and electrical systems.

They should have fixed your horn.

I bought my H2 from Classic, took it there for service and never a problem.

Good Luck.
