08 diesel van. No crank, no turn signals, no blower motor.
With key in run position truck starts by jumping out the relay to get it to turn over. Blower works if I jump it out as well. Everything else works as it should & drives normal. I've been reading a lot for days & noticed some differences from e to f series in reference to part location & wiring. Took ign switch out, took it apart, looked fine. Checked all fuses under hood & #22 under the dash. I'm leaning to neutral safety, but wire colors from another thread in position #4 are not brown or pink like my dually's. Im on the way out the door to buy an ign switch just to rule it out. (& some relays just in case?)

 

You may not get a lot of response, not many E series users on here, mostly F series.
Myself I have done my best not to work on any E series if I could help it. Not a big Van fan.

 

Do you have power to fuse 22?
How about to 37?
I know you said fuse 22 is not blown but I want to make sure its hot.


The Vans are great! I love towing with them on a long trip because you have room to bring anything and everything you think you might need.
The gas motors are easy to work on. When you get a 6.0 crammed into one they suck though.

 

If both are hot you should have power to pin 9 of the switch at all times.
They list it as light green/violet.


The power out in crank position is pin 5. White/pink.

 

Ok so I put in the new switch. Nothing....
Then I took out fuse #'s 22 & 37 tossed them aside, (they were both good?)
I then put in new fuses & boom it works? I have no root cause to blame. Any ideas?


((Ooh & thank you very much for your input.))

 

One of the fuses could look good but not make a complete circuit or you might have a connection issue where the blade meets the fuse block.

I've seen fuses that looked good that were duds.

 

Always check fuses with a meter, visual will bite you in the butt.

 

There was a TSB awhile back talking about the possibility of the blades of the fuse not going in the clips in the fuse box. It doesn't look wrong- the top of the fuse isn't crooked or sticking up more than the others but the blade of the fuse is between the plastic part of the fuse box and one of the clips and can cause difficult to diagnose, intermittent problems.

 

I never saw the TSB but know, personally, a guy that happened to. He had the truck towed to dealer and that's what they found.

 

Wich fusecwas bad? That would help to give you information

 

Neither fuse was bad. I checked them both out of the van with a fluke meter.
