Stealership ?'s please help ASAP

[hummer74]

Ok, well let me give you the story first then list the questions. First, there were some things going on with my H2 that I needed the stealership to look at so I bring it in to Classic Hummer Grapevine on Saturday. Here are the things I bring it in for:

1. Stuck in 4hi-lock and makes bad noises when turning in 4hi-lock
2. Horn works intermittently.
3. Wind noise from the windshield surround.
4. Light methodical ticking that's fealt in the steering wheel and gas pedal when moderately accelerating around a lazy turn.
5. Change out rear marker light.

So I go over the problems with the service guy and he says "ok, but we have a problem. I can't give you a loaner car because you are under the extended warranty." I tell him that is not right, because I brought my truck in a few months back and got a loaner, no questions asked. He says, "let me speak to my manager and I'll be back." The service guy gave attitude during the whole conversation. Ten minutes later he comes back and says the loaner is out front and I can go.

Fast forward to today (Monday), the service guy calls and says, "The 4hi-lock problem is normal. Somewhere it's written that you have to back up thirty feet to get it out of 4hi-lock. Also, its normal for it to make the grinding noises when turning in 4hi-lock. The horn has been intermittently working due to excess grease on the contact. That is NOT covered under extended warranty and that will be $80 to fix if you choose. The wind noise from the surround is NOT covered under extended warranty and will be $80 to fix if you choose. The ticking is caused by the wear on your front tires. (Even though I have brought the truck in for the same problem before when the tires were in great condition.) And if you want to change out the bulb it will be $20 something dollars." I say, no thanks i'll change it myself. He then says I don't have to pay my deductible because no work was done, but that I'll have to pay a $99 checkout fee for checking out the problems.

My questions to you all are:
1. I've never noticed prior to now, that you had to backup to get the truck out of 4hi-lock. Have you?
2. Do you have grinding noises when turning slowly in 4hi-lock?
3. Don't you think that they should fix the horn (safety issue) under warranty? especially since they had to open it up to find the issue?
(how hard is it to wipe off grease when you already have it opened up?)
4. Shouldn't alot if not all these issues be covered under extended warranty?
5. Why do I have to pay a stupid checkout fee, to see if something is broken or covered under warranty?
6. What do you guys recommend I do?

Any help would be really appreciated, as I am going to pick up the truck tomorrow morning. Thank you so much in advance for your help and comments.
