Re: getting wires thru firewall
Start by looking under hood at firewall, there is usually rubber grommets for other items that you can use to poke in along side of them. I usually go in by speedo cable, steering shaft are, just make a small **** if you have to. Look around for one that is closest to your antennae mounting location. Cellular antennae, I guess stick on the glass type not available, or preferred?

ok, You are going to have to remove the front passenger fender to access the Antenna location. If not the whole fender at least the splash guard in the wheel well. The good news about this is you have to remove that splash guard anyway so if you get that out and see you can reach the antenna then you can do the job without removing the rest of the fender. I assume you mean replace the whole antenna assembly in this response, if your just talking about the wire part that sticks up all you have to do is put a wrench on the nut looking end right where the wire part of the antenna starts and wrench it off like any other nut. Now, on the assembly, once you can access the lower part you will need a spanner wrench to remove the collar that holds the Antenna assembly in place. You can remove this without a spanner if your VERY careful and use a regular flat screwdriver on a slight angle in the little notches and turn the collar counterclockwise to remove it. Once that comes free the whole assembly will drop through to the fender area where you can remove it. For the wire it should move freely through the upper firewall area. Make note of that area because you will have to put the new wire through that area so you can connect it to the radio.
if part is still left where antenna was take a pair of pliers and turn counterclockwise(left) to remove old piece left. go to most auto parts stores and they should have an original equipment replacement antenna
open front door you should be able to grab antenna cable with a wire clothes hanger.fish wire through grommet behind the kick panel.pull radio out fish antenna wireunder dash to radio opening and then plug into back of radio antenna jack then reinstall radio
This is probably way more information than you need, but here goes. I
just had the same problem with my dads 2001 YUKON and wanted to put the
stock wire back. It was not easy, but it can be done.
Remove the glove box, and plastic side panel on the dash As you are looking through the removed area, there is a silver computer there, remove the bracket and move this computer. Behind the computer there will be the plug in for the antenna. One side goes to the radio, the other to the fender. Unplug
the cable, and tape/fasten a length of wire to it so that when you pull
it out, you have a guide to get the new wire back through the firewall. Remove
the old ant. and then take the guide wire and fasten to the new cable.
Pull this guide wire through while someone else is feeding from the
fender area. Replug it, and reinstall the computer and glove box door.
be aware and make sure that the new cable with stud matches the ant.
mast. GM changed the size of the stud (for unknown reasons)and you may
need to get a new matching mast. I could not use my old one
1. Disconnect negative side of battery.
2. Wait at least 2-minutes to de-energize the airbag system
3. Remove the glove box from the dash.
4. There will be a coax cable towards the top of the opening. Disconnect the antenna cable lead.
5. Remove the right kick trim panel. There should be no screws just clips.
6. Loosen the rubber grommet insulator from the door hinge area. This is a rubber accordian style guard for wires located between the "A" pillar and the door.
7. Pull the antenna cable out of the dash area to the hinge area.
8. Jack up the front right of the vehicle. Support with Jack Stands. Do not use only the Jack! Use the jack as a back-up in case of Jack Stand failure.
9. Remove the right front tire.
10. Remove the right front wheel housing splash shield. There should be 3-push type retainers and one 10 mm bolt below the bumper.
11. Slide the plastic cover (on the base) up on the antenna mast.
12. Use a open end wrench to unscrew the antenna mast at the base and remove the antenna mast.
13. Remove the plastic cap from the base nut on the base and remove the base nut.
14. From underneath the fender: pull down the antenna base. And pull the cable towards you - out from the door hinge area into the fender area.
Good Luck! Installation is reverse of above.

To answer your question about time. Labor time to replace the assembly is .9 of a hour. I tried to replace one yesterday and I can tell you that it will take longer then a hour. First off, it looks like the fender is going to have to come off do to the fact the Antenna wire that runs to the radio goes threw the firewall behind the fender. Then it runs behind the heater/ac box until coming up behind the radio.
There are 2 bolts that hold the antenna to car, 1 is the Nut on the antenna mass.The other is a 10mm bolt at the very bottle of unit.
