It seems a several folks have run into this issue when installing LED bulbs into the driver side door. I suspect that somehow in the process of removal or installation the two fixture wires got shorted together and it damaged a circuit in the ECU. This happened to DocTock993 and the dealer replaced it twice:
LED Interior install problems - fuses blowing
You may need to get a new one, it’s probably quite expensive.
I’ve replaced my door LEDs numerous times with no problem. Here’s how I did it. See the photos below.
-It’s best to disconnect the battery negative lead before this electrical work.
-Remove the light fixture from the door by prying with a small thin blade screwdriver.
Remove the two-wire connector plug.
-Disassemble the fixture to gain access to the bulb. Toyota fixtures are a kind of puzzle to figure out. With the same screwdriver carefully pry open the back of the bulb housing. Note how those two grey tabs fit into the clear lens cover.
-Pull the bulb straight out. No twisting.
-Examine the brass contacts in the socket, make sure pins look good to grip the bulb.
-Install new bulb, push straight into the socket.
-Install the two-wire connector plug.
-Re-connect the battery and test the bulb. If the door is open it should light. If not, disconnect the battery, pull out the LED and reverse it in the socket, test again.
-If all is well, carefully re-install the grey bulb cover. Pay attention and insert the grey tabs first the rotate the rest of the body down and snap it together.
-Install the whole fixture into the door.
You’re good to go!
