Question about 2004 Cadillac CTS

Radio effected by brakes?

Just recently my Cadillac CTS 2004 developed this problem: the radio goes from clear to full of static when the brakes are applied.I have tested this everyday just to make sure it was not a fluke. When I apply the brakes to stop at a red light or stop sign, the radio station becomes full of static --doesn't matter what station it's on. I can tap the brakes and evoke the same response from the radio.

Any idea what's causing this? Wouldn't you know my warranty expired only about 3 months ago.

If this happens when the car is still you have voltage interference between brake light voltage & antenna. If this happens from motion check all wire connections, loose antenna wire, to antenna.

The factory radio, in my Cadillac CTS 2003, comes on, but only has static. No radio channels will play. Any suggestions?

The antenna plugs in to the back of th radio. it could have came loose and fallen out. When you pull the radio and if the anteena is secure in it, then you have lost the receiver in the radio, very rare, Replace the radio at this ppoint.

I just bought a 2004 Cadillac CTS without navagation and can not figure out how to set the clock. Owner's manual doesn't offer solution.

This worked on my 04 CTS. This is a CTS without the GPS.

1) Turn key to On or Accy
2) Wait for the radio/clock display to load up.
3) Push the Tune/Select button at the lower right of the radio display. Nothing will appear to change.
4) There is a button to the right of the radio diplay with two horizontal lines on it. Push the lower of the two horizontal lines. The clock set option should appear.
5) Turn the Tune/Select button until the time is correct.
6) Push the Tune/Select button to lock the time in.

Hope this helps.

The AM/FM radio in my 2003 CTS faded to just

This sounds to me like the antenna wire may have become loose in the back of the radio. It just took a few weeks for it to become free. :) If you can maneuver your arm behind it, you should be able to push the connector back into the hole in the back of the radio. But the safest and most practical way to do it is to remove the radio from the dash and plug it in that way. :)

I hope this helps! Let me know if I can be of further assistance. :)

How can i remove stock radio fron cts 2004

1. Open the ash tray and remove the felt lined insert, behind it is a bolt you need to remove.
2. With that bolt removed you can pop out the ash tray/climate control unit, and you will be able to see the two bottom bolts for the radio.
3. Above the radio you will need to pop out the ac vent, it isn't screwed in so you just have to pull on it and it will pop out. With the vent removed you will see the top two bolts for the radio.
4. Remove the 4 bolts and the radio will slide out.
