Appears to me you just replied to a thread that is over 7 years old too
I've found lots of valuable information in old threads, haven't you? I was not trying to help out the OP...he's probably already fixed, replaced or bought a new car. It took me 3 months of fiddling with mine just like the OP until I found somebody with more experience to help me.
I was merely giving others help in their quest to fix that really common problem with the DC/DC power boards.
Mine had a blown power resistor (3.3 ohm). You are right, no amount of soldering was going to fix that. $2 part at RadioShack did though! Easy to fix if you put it in the right hands. I didn't even know what a power resistor was until [email protected] explained it to me.
I'm a newbie on this board...go easy on me. I was just trying to help.
