Where is the wiper relay located on 1997 f150? My wipers only work on one speed. The windshield washer works well. I already replaced the switch, old switch handle was broke. The wipers still don't work. I can not locate the relay. I believe that would be the next step

  • Is it possible to visually inspect a relay and see whether it is good or bad? like fuses? or we need to take them to an electronic shop?

  • Just replace it, they are fairly inexpensive.
