when i bought my vr4 the back spoiler wasn't working so the guy took off $400 for me to fix it. turns out every time i wash my car the spoiler seemed to work for a little while after words. by the 2nd week i owned the car the spoiler just decided to keep on working so the guy practically gave me $400. so if you are having problems with your spoiler WASH YOUR CAR! i think i was just lucky though so don't expect it to work.
