Soldering the board is not a temporary problem. I studied Electrical Engineering, so I ought to know. They just didn't want to do it, and I don't blame them, as it is easier to swap the part. I did mine and it worked great. Didn't cost me a penny.
Glad you got it fixed. I know exactly how dangerous it can be. I wouldn't let my wife drive the car for fear that she would forget to hold the brake and let it lunge into the car in front.
