2000 Honda Accord dimmer control failure?

Hi, i have a 2000 honda accord with dimmer control unit not working. I am a tech and work for an electronic design company, we build and design complex electronic circuits for consumer and industrial companies, so basically i can fix almost anything elctronic. I opened the dimmer control unit and there is a motorola mosfet driver for the dimming circuit that is burnt. However that is an industry part number from the UTA Automotive factory. It has to be a Mosfet because drives cooler, but it wont cross to any motorola part. This mosfet has markings (004) and (20N) from Motorola. I believe it is a size TO-252 case. Would anyone happen to know the Motorola part number? Honda wants 300 dollars to replace a 1 dollar part. This would help many honda accord owners to fix their unit and just replace mosfet driver instead of Honda screwing owners for a bad design that they didnt use a proper heatsink... my email is bld_mld@yahoo.com|||Seems the 2000 Accord had a recall on that part. Perhaps you can get that serviced, and see what replacement mofset driver they used.
