If you didn't know already I have a 98 250 LD.. which doesn't seem to be very much differnt than a 150.. ANYWAYS

So my problem is that I have just ONE corner running light out. This is the same corner light used as a blinker. First thought, must be a bulb. But I figured I would have noticed if the blinker indicator on the dash was blinking faster than norm like most do when a bulb is out. So I threw on the blinker and it works,.. bulb is fine. Turn it off, with parking lights on and nothing.

I figured I should inform you that I have not yet had time to go through the fuses with the manual. If I were to guess, I would say all the parking lights were on ONE fuse or maybe front and back seperatly... and besides, my rear parking lights work fine.

SO WTF

 

Remove the upper and lower steering column shrouds and make sure none of the locking tabs on connector C258 at the multi function switch (the larger of the two) aren't broken, allowing a pin to back out and not make connection.

Depending on what side and end of the truck you're on, you're looking for pin 9 (light green/orange) for the left rear, pin 5 (orange/light blue) for the right rear, or if it's the front, pin 3 (light green/white). At C258, you've only got one wire feeding the front turn signals, after which it goes to splice S246, with one end going directly to the instrument cluster for the turn indicators there, and from the cluster it goes to splice S247, to connector C159, to the right front turn lamp. For the left, it comes off C258, to to S246, to the instrument cluster again for the signal indicator, then to C159 again for the left. Confused yet?

In any case, start at the hardshell connector C258 on the multifunction switch, making sure no terminals are backed out from it.
