We have a 2016 RX350FSport. The map/home button in our center console doesn't work. There is a circuit board with a springy nub in it, and the spring is flattened. It's labeled 'sw1' in the image.

Dealer wants 2k to replace the whole unit. Does anyone know where/how I could purchase just the board pictured below? Or even repair it(doubtful)?

That should be a warranty item if your RX is still under warranty. If no warranty, try getting one from Rancho Cordova Lexus Parts in California. They may have one, or possibly a circuit board with a good switch that you can use to do your own repair. $2K for a $25 circuit board is robbery.

 

Try to contact a local circuit repair shop, they may be able to help.

 

You won't find that piece by itself. You can swap it out though with a used part. Here is an example.

@16rx350f I did this swap for my 2015 GS350 FSport from the 2016 GSF. Pretty straightforward. Here is before on top, and after on bottom.

 

Thanks to everyone for all of the solid advice.

Ill talk the the dealership tomorrow. The car is in for 60k service (we have 100k warranty), but they already said 'no' initially. My wife talked to them, and they told her they wont cover it because something spilled on it. Im not sure how they came to that conclusion. But Im also not really up for a huge confrontation.

I think then Ill:
1) look for a circuit repair shop. It could be simple for someone who knows what they are doing.
2) Ill reach out to Rancho Cordova Lexus Parts in California. Dont have high hopes, but cant hurt.
3) Ill check out ebay. Ive already taken it apart once, to get the picture of the circuit board. So I feel comfortable with doing the replacement myself. $300 isnt great. But its better than $2k (which I would never pay).

 

Those switches can be purchased at an electronic parts store like Digikey.com under Tactile switches switches. The hard part is finding the part number and manufacturer. These switches have a bubble membrane under the button and can rupture if pressed or hit hard. They are simp,ego desplder and solder on the board.

 

Could you get one out of a vehicle that has been totaled in an accident?
