Q: Ghostly, seemingly unrelated electrical stuff

asked by on October 26, 2016

Hi, With my '02 ford explorer, the gas gauge doesn't work, nor does the 4 wheel drive, it tries to stall when the headlights are on and the left blinker is engaged. I was thinking it could be the GEM. Do you know if a faulty GEM could affect any or all of these things?. Thank you!
