New C5 owner needs help
1. How to replace drivers side courtesy light.
2. When I put a CD in the player it won't go in all the way and get
an ERR code.
3. The under the hood light does not work nor does the Electrochromatic
rear view mirror and map lights.
These are not big issues I realize, just would like to get them working.
Otherwise the car runs great, one owner,63000 miles on it.
Thank You ALL in Advance.
Here's a picture from the front of the car looking down along side the radiator.

Since you stated it won't go all the way in, you might have to remove the unit and see what is holding it out. Possible misalignment of the loading tray, possible something stuck inside. If those are the problems, no other way except to take it out and inspect it or replace it. A lot will depend on your knowledge of working on something like this too.

The radio does work. However CactusCat mentioned something about
TheftLock code and that if I pull the fuse for twenty minutes I may need to know what that code is. I just purchased the car and would not have a clue of what the code would be, how would I get that code or get around it, if there is one, I don't know that there is or isn't.

This is what I used to unlock a half dozen GM head units to try in my C5. (I was able to unlocked every one, but none would work in my non-Bose car.)
Unlock C5 Radio (THEFTLOCK)-- 1 of 1

The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode, NOT in INOP mode.
Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Y2K Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere).
1. Turn the ignition ON (The radio displays LOC)
2. Hold down the Radio Presets 2 and 3 buttons for six seconds
3. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step.
4. Press the AM/FM button
5. The radio display changes to another three-digit number. Write this number to the right of the first one.
6. You now have a six-digit number, the first three digits are from STEP 3 and the last three digits are form STEP 5
7. Call 1 800 537 5140 08.
8. Press 1 then # (pound key). You’ll hear “Invalid Code, try again”
9. Press 139010 then # (pound key). You will be asked to enter your four or six digit code followed by * (start)
10. Enter the number from STEP 6 then * (star key)
11. Listen to the four-digit number and write it down. It will be repeated twice
12. Turn the ignition ON (The radio displays LOC)
13. Use the MN and HR buttons to enter the code from STEP 11
14. Press the AM/FM button. The radio display changes to SEC, your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction on page 3-27 in your Y2K Owner’s manual. Use the code from STEP 11 instead of your personal code.
Good luck... GUSTO
