Question about 2004 Toyota Sienna
The ECU on my 2004 Sienna passenger HID light went bad due to the condensation in the light, or at least that's what it looked like when I opened it up. The ballast was all corroded. Anyway, I searched and searched online for a way to fix it without paying the dealer $900. I just fixed it today for $92. I got the replacement ballast brand new for $92 shipped from The Retrofit Source at this site: http://www.theretrofitsource.com/product_info.php?cPath=26&products_id=161
Then I searched for an online manual for 2004 Sienna, found that, and went through the procedure of partially removing the bumper cover, taking the screws for the light fixture out, turning it on it's side and replacing the ballast. It took me about 2 hours to do the whole job, and everything works fine.
By the way, I got the part from The Retrofit Source in about 2-3 days without paying any expedited shipping. They were extremely helpful on the phone, delivered earlier than I expected, and saved me $800!!

Siennas have a problem with the headlight ecu which is an all in one unit with each headlight assembly itself. its an unavoidable expense because the headlight wont work without that computer and that is the retail price for the part. you may be able to find the part cheaper at a junkyard or online.

If you have the HID bulbs, and there is moisture in the bottom of the assembly, the high voltage box at the bottom will not work. this requires removing the whole headlamp, removing the circuit board from the bottom and drying out. I have done mine twice before finally finding how water was getting in at the top seam of the lamp assembly. You will have to dis-assemble part of the wheel well and bumper cover to gain access to all the mounting bolts. Best of luck

The bulb has to be lined up in the headlamp housing before it will fit properly,is it a 80 dollar bulb?or 8 to 15 dollar bulb?the 9006 bulb,the cheaper one has to be aligned just right,or it will not fit,and it can be difficult to do,but the 80 dollar bulb,just fits one way only.
