Fleetwood wiring help

I have no power to the front parking lamps, and cornering lamps. I have headlights, and turn signals only up front. I found the wire to be light grey with black stripe that powers the four in the headlamps. I can see the back of the headlamp switch, but don't see the grey and black wire. In the fuse box there is a tail lamp circuit, and a parking lamp circuit. The parking lamp circuit has constant power to it, while the tail lamp circuit only has power with the switch, but if I take out the fues for the parking lamps, it kills power to the tail lamp fuse. I am so confused with this, and how far back into the dash the grey and black wire goes. It does not go to the switch, and on the backside of the fuse box, there is a purple wire to the tail lamp fuse, and a orange wire from the parking lamp fuse.

Does anyone have a copy of a wire schematic that they could let me see

Also there is a wire harness with four wires coming down from from the steering column. It is the cruise control wire harness. It has one connector at the end that looks like a spade shaped circuit board. I can not figure out where it plugs into.

Any help would be appreciated.

If I can get my FSMs back before you get an answer, I will help you out. But they're for a 95.

Thanks Bill. I have 94 b-body line FSMs, but nothing there for this.

Oh. Then I probably can't help any. Sorry.

Yeh, I need someone who has a D-body line FSM.

Grey and black wire goes to the fuse block
Corner lamps fuse 10a #41

I have the whole 2 book set of d body manuals...

Grey and black wire illuminates my parking lamps in the headlights. I put direct power to it at the connector under the air filter box, and all four lights came on. I thought it was a lime green/black stripe wire coming from the parking lamps, but power did not illuminate them .

So what's the problem you have no park lights and corners don't light? Any problems with tail lights?
Gimme specifics of what's working and what's not.

Everything outback is working. No issues back there. Front turn signals, and headlamps are the only lights working up front, including the horn since it shares the harness. I have no front side marker lamps, no cornering lamps, and no parking lamps in the headlights. Bulbs all good. I can power everything directly at the connector under the air box and every thing works as I move power to each circuit. So I know we have good grounds. But I checked them first.

Ok well tracing the grey/black wire from lights it goes to the fuse block #41 from there it turns to a purple wire and goes to the 87 terminal on the park lamp relay. Coming out if the park lamp relay is orange which goes to the park lamp fuse #31 (20a) which gets it hot all the time from maxi fuse #11. also coming from the park lamp relay is a Brown and white wire that goes to the head lamp switch
My manual is for 1996, but should be close with these circuits.

Sounds correct based on what I saw behind the fuse panel.

So do you have power at the relay with a test light?
Before it?
After it?
Power from the switch?

Not sure yet. I did not get that far before I lost day light. I am not sure where the relay is.

Convenience center under the dash drivers side
Should be 6 relays in 2 rows of 3.
Bottom row first one in from left is the park lamp relay
Bottom row last one is the horn relay.

Since both are in the same block and you don't have a horn I would check power going into the whole block.

I have the horn. It works. I only mentioned it since it shares the same harness. Maybe I will try swapping the horn relay with the parking lamp relay.

Ah ok I was confused. The park lamp relay is powered by the #31 fuse check for power there too.

I have constant power there.

Then deductive logic dictates an in operative park lamp relay.

Maybe you need to drive up to a corner before the lights come on....
It IS a caddy after all
Sometimes you need to think outside the BOX

Not helping?
OK good luck

Lol this is a stock looking fleetwood, shouldnt have to sneak up on hookers like that.

Before talking to you I had no idea there was a parking lamp relay.

I wasn't being a wise ass
I just mean I bet dollars to donuts it's that darn relay. Has to be right?

I hope so. I love Donuts.

My biggest concern was that I had found the remains of a remote start system. It was hack going in, and worse when they took it out. All kind of wires cut. I was able to figure uot what was factory, and what was not, and cut out the remote start wires. I was afraid that maybe when they removed the system, and cut the wires, that maybe they had cut the parking light wire. But after getting everything out, it appears to be fine under there.
Now I just have to find out where the cruise control harness plugs in under there.

I'm at work now, but as soon as I get home I'll take a Peek-a-boo at the manuals again.

Yup, that's the cruise control. '94 and '95s are different on the ones that I looked at. I think cruise was a rare option on 9C1s so you can just leave it unplugged if you are still going the clone route.

Power to relay, relay works, still no lights. I can't find the grey and black wire under the dash. Not even sure where it goes first once inside.

It says grey and Black goes to the fuse panel.
If you have a test light I can walk you through the diagnosis listed in the book if you want.

I have been out there with the test light. The parking light fuse #31 has a big fat red wire coming into it, and a small orange wire leaving it. The relay has two powered wires. Both are orange, and two other wires. One was brown or black, I think the other was too. If I pulled the fuse for the parking lights, I lost power at the relay. So far so good. None of the wires I see in the back of the switch match the color of any others that have been mentioned.
Can you take a pic or scan a copy of what you are looking at, and post it Indigo?

Also. What is the last thing in line before the parking lamp bulbs? Is it the fuse, relay, or switch? Is there seperate wires coming from the switch to power front and rear, or one from the switch that powers both? If I can find the last thing before going to the lights, I may just run a new wire from that point.

The last thing online before the lamp is the CORNER LAMP FUSE....
Before that fuse is the park relay.

The PARK LAMP FUSE is powered by a maxi fuse (I assume the red wire)
It then has 2 ORANGE wires coming out that BOTH go to the park relay. Out of the relay it should be PURPLE AND BROWN/WHITE
the purple goes to the CORNER LAMP fuse
The brown and white goes to the:
-Remote control door lock
-Central control module (another relay)
-And the head light switch.

The purple wire that goes into the CORNER LAMP FUSE comes out of the fuse and turns black/grey

Any idea where that maxi fuse is located?

Maxi fuse is in the engine bay... HOWEVER that is the source of power, since you already know you have power at the #31 fuse AND at the relay you know it's good there.
Do you have power at the #41 fuse?
How about at the brown/white wire at the headlamp switch?

Another thought Bill, did they not work since you owned the car?
HID's interfering with operation?
I had a set thy made the high beams all screwy one time.

Power at #31 and #43. not sure about #41. I know the cornering lights do not come on at night when turn signal comes on.

Lights have been FUBAR since I purchased the car.

#41 is specific for the corner lights, but also controls the radio, turn signal switch, and instrument cluster.

If you have any of those working, I'm assuming power is there.
Soo I would check the headlamp switch when set to park lights to see if power is leaving the switch.
After that follow the grey and black wire back to the fuse panel... Turn the park lamps on and probe the wire in small increments from the fuse block down to the lights and see if there is a break.

-OR-

Remove park lamp RELAY
Test light to ground, probe terminals D1 and D3
Light on?---->with relay disconnected, turn park lamp on and connect test light between term D1 and E3 (go to step 2 if light is on 2a if not)
No light?------>break in the orange wires between fuse 31 and relay

Step 2 ( test light is on)----->reinstall relay, test light to ground back probe terminal E1
Is the light on? Go to step 3 if not step 3a
Step 2a (test light off)----->check for break in the white and brown wires coming out of relay... All 3 places the go to, also check black and white GROUND wires if they are ok replace headlamp switch.

Step 3 (light on from step 2) check and repair break in purple wire between relay and fuse 41, if that wire is ok then repair break in black and grey wire between fuse panel and the actual lamps

Step 3a (light off in step 2) check connections at relay connection and if ok replace relay.


Before you ask the terminals being probed in the relay terminal are as follows:

D1- top left (85)
D3- top right (30)
E3- bottom left (86)
E1- bottom center (87)

Gota get this fixed now. My Inspection guy, (Yes I actually know a guy ) said no way without the lights.

Indigo
Is there a twilight sentinel module like on the other b-bodys? Is any of the wires that are suspect run through it?

I really wish you had the time to come down so we could chase wires.
How are the grounds to the actual sockets? My Caddy has a broken socket right now and it causes the turn signal in one side to blink really quickly.

The twilight sentinel circuit is separate from the park lamp circuit.
I believe full head lights come on at twilight. Corner lamps have nothing to do with sentinel
Did you follow the steps I listed above?
What did the test light say?

Mystery solved! Indigo, you are the man! I found the cornering lamp 10 amp fuse #41 blown. Replaced it, and everything else came back too.

Thank you so very much. I probably would have never looked at that fuse. I was thinking the problem with the parking lights kept the cornering lamps from coming on, not the other way around.


Now if I can just figure out why my locks unlock and then lock when I put the car in park. They should lock when the car goes into gear, and unlock when you put it in park.

Glad that worked out. Ok problem 2:
LOCKS

so hen you put it in gear doors lock as they should?
And when you stop they unlock and then lock?

Check it now that you repaired the fuse.....Auto Door locks run on that circuit too.

Locks do nothing until I put it from gear to park. Then they lock and then unlock.

I will check to see if they are functioning correctly now. Thank you so very much.
