My SE's steering suddenly stopped working so I pulled the pc board up and unscrewed the piece of plastic that is over the suspension springs and I found tons of little gears and a ball of lint so I took out the lint with tweasers and my car went back to its normal steering (crapy) and all was good. Open yours up even if it isnt screwed up to prevent this from happening.
BE CAREFUL! make sure you hold your zz up in the air or you may have trouble putting the parts back on or even lose the springs!
