Just changed the heater core on my 87 GN, the fan works on low and med speed will not work on high speed. It worked fine before!

Hey Scott, thanks for the reply a found the problem, I have a wire problem, I checked everything and finally I started moving the wire harness and it started to work. It must be a broken wire or bad ground. :shiny:
