SOURCE: replace factory radio on 2002 yukon xl

all you gotta do is carfully pry the dash panel off (prying from the far left end is easiest) completely remove panel. then there are 2 clips that hold the factory sterio in place. push on the both clips while pulling the radio out. simply disconnect the wiring harness from the back of the radio. using an adapter avaliable at your local radio shop (scosche p/n gm02, mdarb and gm1483b) wiring harness, dash install kit, and antenna adapter. then simply match the colors on the new radio's harness to the adapter harness, crimping each connection with a "but plug". then simply follow the instructions included with the dash install kit to assemble the kit.connect the antenna adapter to radio, plug in all cables. test to see if everything works properly before the final install. install sterio into dash install kit, re installing kit where origional radio was. then simply put the panel back in its place by firmly pushing on it untill it snaps into place. then enjoy your new radio!

SOURCE: Factory radio reception failing

I would suggest installing what is called a filter capacitor.You can get these at most car audio shops or a electrolytic capacitor rated at 16v or higher and around 30uf (the capacity is not very important) you connect it from the Positive to the Negative on the radio. The idea being a capacitor will allow the A/C current (noise) to pass through to ground without going into the radio and this is usually the cause of poor reception.

Another possible cause could be simple a poor quality antenna, some manufacturers are going cheap on the antennas since most people don't listen to the radio anymore. You could try to screw an antenna off of a different car onto the base on this one and see if that clears up the problem, they are a some-what universal thread.

SOURCE: service brake booster display

Your brake booster is the heart of your power brakes. It runs off a vacuum from the intake to booster. Your brakes will still work as long as they have fluid. They'll just get stiff. It probably means you need a new one

Why will my Xm radio work but the fm radio won't?


Troubleshooting the problem may depend on which of several radio options is installed in your vehicle. However, the most probable cause is the antenna. Two different antennas are involved here - one for XM (satellite), one for FM (terrestrial - window type). To start, I would check the FM antenna connections at the window and the radio and the cable between them. If that isn't the problem, the radio is probably faulty.

Can you provide me with additional information? Such as, does the brake pedal go to the floor when applying the brakes, are the brakes spongy, non responsive? Is there anything leading up to this issue, such as a minor accident?

I have a 2001 yukon and am wanting to change out the radio. Is the radio going to need any extra parts due to anti theft security?


Depending on what radio you install you will need an installation kit so you can plug in your OEM wiring and not have to splice and decipher factory wiring. Check with Best Buy or Crutchfields' (online)

I have a 1998 GMC yukon and the problem is that


The Master Booster is located in the Engine compartment. You shouldn't have to touch anything under your dash at all. The master comes unbolted, you slide it out slightly to disconnect and hardware that may be connected and then remove it. GMC sometimes add connectors to the linking parts between the brake pedal and Booster but they can be disconnected and should be disconnected from the engine side of the firewall. I recommend you get the Haynes repair manual on your vehicle before continuing that repair.

Just changed radio on my 01 Yukon XL and now the speedometer doesn't work


Double check your wiring on the radio. The factory radio has a wire that comes from the vehicle speed sensor. When you speed up, the radio gets louder. When you slow down the radio gets quieter. That wire may go into the radio and then to the speedo depending on how the vehicle is wired. You may have to connect that wire to another (check wiring diagram). Another thought is that you accidentally hooked that wire up to something wrong and it blew a fuse. Good luck
