XC90 Radio bulbs replacement

Want to avoid paying a dealer $250 to replace your burned out XC90 radio bulbs? Here's how:

You'll need Volvo part number 9148908 ($11 per bulb). I hear it is Honda part # 35505-S84-N01 also

1. Put blocks on the wheels
2. Put the key into the ignition in the on but NOT started position and foot on brake to shift the shifter into drive (engine is NOT running)
3. Gently but firmly pry the rear of the shifter trim up and out
4. Pull the entire shifter trim towards the rear of the car (it does not have to be removed fully)
5. Remove the 4 exposed torx screws at the base of the stack assembly
6. Pull out the lower part of the A/C head assembly
7. Gently pull down and out on the A/C head until free
8. Remove the 3 wire assemblies from the A/C head and set the head aside
9. Now grasp the entire stack assembly (the main housing, not just the radio section) and pull from the bottom down and rearward until it is loose
10. Carefully pry the tabs on the radio face place (4 on bottom, 2 on top) until face plate is removed
11. Use small phillips screwdriver to remove the left or right radio control pods
12. I chose to leave the power connected (maybe not wise, but hey, I like risk) so with the parking lights on, I could see easily now which bulbs were burned out. There are about 10 or 12 bulbs total between the two control pods. I had 5 burned out bulbs. (They cost me about $11 each at the dealer, ouch!)
13. Using a tiny standard screwdriver, turn 1/4 turn counter-clockwise to disengage the bulb, and tip the pod over so the bulb drops out.
14. Swap the tiny green cover "condom" off of the old bulb and onto the new bulb
15. Install the new bulb, turning it 1/4 turn until the slot is parallel to the other slots on the installed bulbs.
16. Repeat for all burned out bulbs
17. Reinstall the pods
18. Reinstall the radio cover plate by snapping it on until all tabs click
19. Tuck the stack assembly up and forward until it is back in place
20. Install the two stack retaining torx screws
21. Plug the 3 wires back into the A/C head. Note that the main power wire goes through a hole in the cover stack
22. Reinstall the A/C head unit (this is the hardest part of the job) - it requires careful alignment and a final upward snap on both sides pushing up from the bottom
23. Install the retaining two torx screws on the A/C head bottom
24. Reinstall the shifter trim plate by sliding in the forward edge and firmly snapping in the rearward edge
25. Go have a beer, since you saved yourself $200-250 with about 15 minutes work!

Warning: Be sure you follow Volvo process for disconnecting power before you unplug the A/C head, because otherwise the airbag fault code comes up and the dealer has to reset it. Oops. Makes finding burned out bulbs hard. I guess the best way is to note which buttons are not illuminated before disassembly and replace those bulbs.

Volvo's instructions: put the key to position 'I' and then disconnect the negative leed on the battery, then wait 15-20min before resuming work....finally when all is done, put the key to position "II" and reconnect the battery and all should be well with the installation and no thrown codes.

Thanks to everyone who posted instructions, pictures & part numbers. Having completed this procedure, I still have the entire left side of the radio/CD unit dark. Using a voltmeter, it seems there is no power to the contacts of the bulbs. There is a small set of wires that are almost like a ribbon-cable, but are actual wires, all green, that connect to this side. I would like to determine if the problem is on the board on the left side, or if the problem originates upstream. Does anyone have a wiring diagram or a pin-out diagram for this cable/connector?

Re: (danzig)

It looks the same and the volvo part number is in the IPD part description. Probably worth a try for the cost savings. I spent about $50 for four bulbs. Would have been about $20 at IPD. I don't know if you can change colors. The bulbs in the dash are standard white but are covered with a green sleeve. They connect pretty slick. No wires - they contact a circuit board.

I remeber using radioshack mini bulbs ($1.99 for pair) and just fitting them into OEM socket on my old 850.

If it is an old part number and used on volvo 850, then RS bulbs work just fine, and it is not difficult at all to fit that bulb into volvo socket.

I just replaced a bulb in my 2004 XC90 today. The instructions found here are excellent.

To clear up a couple of things:

wsu_cougar's instructions were a little more accurate in regards to the number of screws and taking out the entire radio/ac head for my vehicle.

I replaced only one bulb, which was causing the numbers 1-6 to be dark on my stereo (as opposed to six separate bulbs).

Also, I got my bulb from Honda and it was a perfect fit. The part # is 35505-S84-N01 and it was $5.26 from my local Honda dealership that had plenty in stock.

Thanks xc90man and wsu_cougars

I know this is an older post, but it helped me out a lot recently so I want to say thank you to the contributers, and also I wanted to add to it with some pics for any novice members. Thanks again guys!

Disclaimer- work on your vehicle at your own risk and cost. Any and all expenses acquired during your attempts to fix, maintain, or repair your vehicle are the sole responsibility of the owner and shall not find this forum, its members, or any other person liable for damages incured on the vehicle.

Begin by making sure you have not had the key in the ignition for at least 5 min. If your quiet, you can hear a faint humming or buzzing- wait until that stops before proceding.

Next-locate the battery located in the rear of the vehicle:
Image


Lift the rear latch to expose the little straps that secure the battery compartment:
Image


Remove latches:
Image

Image


Pull up on string to reveal battery compartment:
Image


Remove the three, 1/2inch battery tie down plate bolts and remove.
Image


You should see a plastic cover now, remove. (If you have a 7 seater xc90, the rear seats have to be up to remove the plastic cover)
Image


Once battery is exposed, remove negative terminal (10mm) and set aside.
Image

Image


Once thats done, now you can start on the radio. Put the key in the ignition and turn to the II postion, step on brake and put gearbox into 'Drive'. Next pull up on the rear part of the trim just in front of the cup holders. As previously stated, it does not need to be removed, so after releasing the tabs simply just manuever it towards the rear of the vehicle.
Image


This will expose the four T-25 torx screws that you need to remove.
Image


After removing the torx screws grab the bottom of the entire stack and gently pull out (some may require a little more force, but nothing too crazy). There is a tab at the very top so after the stack is released from that tab, slide downward, and out.
Image


Remove the harnesses so you can have better access to the unit. I disconnected all except for two harnesses, one of them was the 12vlt outlet. You basically just need to be able to access the four T-25 torx screws behind the radio. Remove them, and then release the 4 tabs located right beside them. Be careful though as this little cover connects the radio and A/C unit together.
Image


Now that the radio is free, you can see the 10 bulbs.
Image


Remove the bulbs that have burned out by taking a small screw driver and rotating the bulb a quarter turn to the left. I turned the unit upside down and let them fall out from there.
Once you have done that, remove the little bulb condom cover, and place it on the replacement bulb.
Image


I used the honda bulb as they were a lot cheaper and in stock. Here is a look at the side by side: Volvo on the left, Honda on the right:
Image

Image


Once you are done doing that, replace everything in reverse order. I took my sweet time as I didn't want to break anything and it took approximately 30min. If I had to do it again, it could be done in 10minutes.
Thanks again guys! Cheers!

Is the battery shown in the pictures (located behind the 3rd row seats in all xc90s? I wasn't aware of this battery and it wasn't mentioned in researching replacing the radio bulbs in other forums / sites.
 
#14 ·
Yes, the battery is in the rear of the car. What I see in these pictures is a carpeted tray over the battery, but below the floor hatch. My car does not have one of these. Is this a feature of a later model, or is my car missing it all together?
 
#15 ·
I haven't checked my 04 2.5T for that rear battery. IPD has the bulbs for $2.17 each. I'll be replacing my burned out ones as soon as they arrive.

Good to know an alternative part can be sourced from another car make.

Bulb replacement question

I have a few bulbs out on my '04 XC90 and want to do this replacement. Does this process need the radio code input at the end? Are there any issues with needing the code for the radio or the radio not functioning afterwards? Thanks.
 
#18 · (Edited)
I just finished changing out the left side (5 bulbs). The sun set on me so I had to finish with a flashlight but the above instructions are spot on. Follow them and you will have no problems. There was no error code when I put it all together and turned the car on. I had some difficulty getting the the old bulb out of some of the slots due to 'stickiness' but I managed to get them out. It's nice to have it working as it is supposed to.... So much for the dealers $200 quote.:p
 
#19 ·
Thank you all for the valuable information. I just replaced 4 lights using Honda light bulbs (part #35505-S84-N01) They look cheaper than the OEM, but they work. One thing I'd like to add is that if you choose to disconnect the battery, be sure to remove the key from the ignition and put the gear in Park.

Again, thank you all for your help, if it wasn't for you, I would have been stuck with a dealer in a suburb of Minneapolis with the worst customer service ever.

Hey guys! Great write up on the overall procedure. I recently replaced 10 lights on my radio unit ( before seeing this thread) and wanted to add a few things to the post.

I actually never disconnected my battery, just carefully removed the head unit without disconnecting the cables. I separated the main backing plastic and was able to get enough angle to replace the bulbs and periodically turn the ignition on to confirm what bulbs were out.

I found these bulbs from mouser and just swapped the blue caps from the OEM bulbs http://www.mouser.com/ProductDetail/JKL-Components/CNW1-23/?qs=6YhTptf0WO1dQPp6ZqLy%2bw==

Mouser Part #: 560-CNW123
Manufacturer Part #: CNW1-23
Manufacturer: JKL Components
Description: Lamps 14V 0.04A

Cost me $5.90 for 10 bulbs and $4.99 shipping.
