ok, In my 76 stingray I have the power window motors and they won't work i ordered them new and both wont work, i hooked them up to a battery and installed them and i am getting no life from anything I tried several batteries and I dont get nothing. any help please.......... and I am considering manual windows, now how would I install them are there kits out there to convert power to manual? I know I can order the parts but is there anything else out of the ordinary with this any help would be appreciated.
