I have a pair of Code 3 Stingers. One works as it should but the other only oscillates from side to side. The motor which controls the up and down portion of the light doesn’t appear to be working. As I compare the two lights to each other, everything appears to be wired correctly. I am assuming the problem is with the motor. Is there anything else I can try? Is it possible to repair the motor if that is the problem and if so is there anyone I can send it to? Thanks for any help.
