Multifunction Switch

[Maree74]

1997 4.0 Standard Explorer
So I've now removed the multifunction switch to start fault finding.
Wiring diagrams are lacking some information when I just have the switch in my hand. I can see the numbers adjacent to all the terminals but I cannot link these to any numbers on the wiring diagrams.
I've tried searching for terminal descriptions but have not found any yet.
Does anyone know of a picture or diagram that indicates what all the outputs/inputs are on the multifunction switch?
Thanks

What is the multifunction switch?

The turn signal stalk switch.

What is the issue?

Best bet is to just replace it, or take it apart and clean it. Both would likely fix your issue. It’s common for these to come partially unhooked and cause intermittent use.

What is the multifunction switch?

Hi, its the steering column switch that controls direction indicators, windscreen wipers and washer, and headlight main beam and dipped beam.
So I dismantled this switch and cleaned it and polished contacts with a fibre glass pen. Resembled and refitted, it works as before but still have the problem of no dipped headlights(low beam) .
The plus side is that I can eliminate this switch in my fault finding..

Multi-Function Switch Wiring? Stuck Blinker

2000 Explorer XLT Original problem was loss of power windows, wipers, interior light, and speedometer. Tracked the problem to a short to 12 VDC in the instrument cluster that was blowing a fuse (GEM/instrument cluster/PAT fuse, 25 or 28). Ordered a replacement instrument cluster at LKQ for...

What you need isn’t in there?

The high beams stay on with headlight switch, and flash high beams when you pull the lever, but no low beams ever?

Yeah, your right.
Checked all fuses now. I've ordered a couple of relays to check them out, after that I guess it's down to the wiring?

Should also be a relay involved.

To test relays, you might be able to just swap the relays with other relays in the vehicle already. Check for voltage at each point in the circuit with a multimeter to see where power stops.

There's wiring diagrams for that in my sig, but to address the MFS pinout:

Thanks J_C. This is great and I'll get onto it tomorrow probably.
My Explorer is outside and its a bit stormy just now - and dark this is just what I was looking for...

BIG apologies to you all !!!!

Turns out that the problem was both dipped beam headlights had blown.

I'd had a breakdown mechanic try to start my Explorer a few days ago (Immobilizer problem) and he used jumpleads and another vehicle to try to start the engine, I think he blew the dipped beam lights ! ! !

Thanks for all help and advice that you guys gave me, I'd give you all a flash of my dipped beams if I could

Jumping the car didn’t blow the headlights.

OK! So I don't know what did blow them... But the new bulbs are working OK.

 

[Mbrooks420]

They wore out.

They wore out.

That sounds a bit like me! Both of us are wearing out together...
