So I have seen a few posts about blinkers and wipers working and quitting intermittently and now it has happened to me. I was sitting trying to make a left turn one blink two blink and then nothing. I tried all the normal avenues such as fuses, relays, bulbs etc. All work good so I checked old threads here on the forum saw that the fuse block could be the culprit, tore it apart pc board and fuse holders are fine. I also saw that junk falls in by the hazard light so I pulled that whole assembly off (including the black box with the electrical contacts) and cleaned it, put it all back together and now if I wiggle the blinker (while in the left position ) I get a normal clicking, like the blinker is working but no lights. I am hoping for more suggestions or a wiring diagram. I would love a service manual and would be willing to buy it if any knows where I could go to purchase it. Its a 2004 lowboy van.
