04 EB electrical issue-delayed acc relay issue?

Also look at the sticky Fuse Testing 101

I may need you to test some fuses depending on the voltage readings you post

Also consider getting this type of fuse holder See attached pic

This can be used to make a fused jumper

Just saw you posted bedrck47 beat me to it

Wasn't in a race I know some people have jobs and can't reply as fast as some of us retired old farts

Will do-I do love to shop at the auto parts store! Thank you.

That is pointing to 200 Volts AC

Move the pointer 5 positions to the left Then you will be at 20 volts DC Also your leads need to go into the TWO holes that are covered by your thumb
Black lead in COM
Red lead in V

I got a reading of 11.96 at both pins.

 

[Fordgirl01]

Great-thank you. I will take a look at it.

I've updated the multimeter guide sticky in the Electrical section with a link to using them. That may help you in using it in the future.

Very helpful multimeter video-thank you!

I’m not sure if this helps with a diagnosis, but upon further inspection of my wires that run beside the rear seat on the drivers side-I found this: coating nicked on green wire, purple wire w/orange tracer and purple wire with no tracer (I taped them back up). On the purple wire w/blue tracer, some of the fine wires seem to be broken so I will cut and spice that one back together (wirh the battery unhooked).

OK Voltage looks good for pin

Now I would like for you to check fuses 15, 21, 1, 102 and 7 to see if any are blown

These fuse are for the instrument cluster

******** UPDATED INFO******

If any of the above fuses are blown replace them Then re-install the delay relay, start the engine and check to see if you have voltage at fuse #22. If no voltage at fuse #22 then proceed to the following.

Remove the delay relay.
Then using a jumper place a jumper between pin 30 and pin 87 in the accessory delay relay
socket It would be best if you used a fused jumper like the one in the picture I sent with nothing bigger than a 30 amp fuse in the jumper
Then see if you have power to fuse #22

Can you read and understand wiring diagrams??

Can you read and understand wiring diagrams??

Thanks again-I will do the things you suggested tonight and post the results. I’m not sure about a wiring diagram. I would give it a try-I’m fairly good at figuring out diagrams! Normally electrical issues intimidate me but I figured it was time I stopped avoiding them!

OK-fuses 1, 15, 21, 102 all had the proper voltage. Fuse #7 has nothing. I took out the fuse, it looked OK but I swapped it for a new one and still nothing. The spot where the fuse plugs in didn't have any reading either. Also while testing fuses with the multimeter, I noticed fuse #8 has no power (fuse OK) and also relay 4 has no power. I see they are related according to the manual. I'm not positive the heated mirrors and rear defrost worked before as I didn't drive this vehicle that much last winter and just bought it prior to last winter. So that problem may be unrelated, but I would like to fix it while I am getting some good advice!

 

[Bedrck47]

OK fuse #7 will only have power when the key is in the start position
Fuse #8 will only have power when the rear window defrost relay is energized.

Go back and read what I posted about a fused jumper for pins 30 and 87 Put the jumper in and see if you get power to fuse 22


Attached prints are for an 03 expy but they are the same for your 04 model

Go back and read what I posted about a fused jumper for pins 30 and 87 Piy the jumper in and see if you get power to fuse 22

OK-thanks. I’m going out to to do that right now!

I will have a look at the prints also. I appreciate this immensely.

 

[Fordgirl01]

OK-put the jumper (with a fuse like you said) on 30 and 87. No key in the ignition, radio came on, fuse 22 had proper voltage.

 

[Bedrck47]

The problem has something to do with the instrument cluster.

Look at the prints on page 13-11 upper left hand side You will see the delay relay

you have power on pins 86 and 30

Look at the relay pin 85 goes to the instrument cluster and when the engine is started that circuit completes and energizes the delay relay coil this in turns closes the contacts between pins 30 and 87 which provides power to fuse 401 and fuse 22 on page 13-12

 

[Fordgirl01]

I see the delay relay in the print above the instrument cluster.

 

[Bedrck47]

Don't take my last post the wrong way. What I am saying is the problem has something to do with the circuit in the instrument panel What you may have to do next is pull the instrument cluster so you can get to the connectors and check to see if you have voltage where it need to be. I'll look at the prints and get back to you

 

[Fordgirl01]

OK!

 

[Bedrck47]

When you look at the relay the coil is across pins 86 and 85 The coil requires 12 volts to work Pin 86 is the positive side of the coil pin 85 is the ground side that is the 12 volts

In this case pin 85 goes to the instrument cluster and a circuit in the cluster must close to provide the ground circuit something in the cluster is preventing that circuit to close.

In your first post you stated

"What doesn't work: electric windows, gauges (instrument lights do work), radio, interior lights, vanity light, under hood light, moon roof, vent windows, automatic headlights, 4wd indicator"

Put the fused jumper back in the delay relay and give me an update as to what still isn't working

Thanks
