I recently bought a new two speed wiper for my 67 gmc and it worked fine when I tested it before install. Ever since I put it in it will not work. I do not have the washer motor on the wiper motor because I didn't think it mattered and I checked the voltage and there is 12 volts everywhere in the circuit all the way to the wires that plug into the switch. The only thing I haven't done is tested the switch with an ohm meter because I do not know how. Could you please explain exactly what you mean by that i do have a dmm so I can if i know how. And any other suggestions to try are welcome
