signals, wipers, brake lights stopped

Hi, I just bought a 2000 ranger as a fishing truck. It seems to work fine except today all of a sudden..no signals. no sound when I turn signals on..no lights. wipers also do not work...they did a few days ago. Signals worked earlier today. brake lights went out, but if I move the steering column up and back down they do work. also if I hold left signal lever down and step on brakes...no brake light on left side..same for right

please help me

Well all are on the Multi-function switch(turn signal bar), so I would say you need to pull off steering when covers and have a look at that connector and it's wiring

Brake light voltage passes thru multi-function switch, so turn signal can over ride brake light on that side.

Multi-function switches do fail, not common but because they are used alot they can wear out.

Also found this "dealer letter", sent out by Ford:
The 11th digit in your VIN tells where it was assembled.
Z — St. Louis (Hazlewood, Missouri)

P — Twin Cities (St. Paul, Minnesota)

T — Edison (Edison, New Jersey)

It should have already been replaced

DEALER LETTER

April 2000
TO: All Ford and Lincoln Mercury Dealers

SUBJECT: Owner Notification Program 00B40: Certain 1999 and 2000 Model Year Explorer, Mountaineer, Ranger, Expedition, Navigator and Villager Vehicles - Multifunction Switch Replacement

REF: Dealer Announcement dated 12/17/98

PROCEDURE (See attached)

OASIS: Yes

OWNER LIST: Yes

PROGRAM TERMS: This program has no expiration date.

AFFECTED VEHICLES
- Certain 1999 and 2000 model year Explorer and Mountaineer vehicles built at the Louisville and St. Louis Assembly Plants through September 12, 1999.
- Certain 1999 and 2000 model year Ranger vehicles built at the Twin Cities, Louisville and Edison Assembly Plants through September 12, 1999.
- Certain 1999 and 2000 model year Expedition and Navigator vehicles built at the Michigan Truck Plant through August 17, 1999.
- Certain 1999 and 2000 model year Villager vehicles built at the Ohio Assembly Plant through August 9, 1999.

REASON FOR PROGRAM
In some of the affected vehicles, the multifunction switch may develop corrosion on the front windshield wiper switch terminals affecting its signal output. The change in the signal output interferes with normal operation of the front windshield wipers. The most common condition involves the front wipers briefly turning on with the wiper switch in the "off" position. In extreme cases when this condition is ignored for some time, wiper high-speed operation may be affected.

NOTE: Owner Notification Program 00B40 is being launched concurrently with Safety Recall 00S04. ONP 00B40 involves the replacement of the multifunction switch only.

Safety Recall 00S04 involves the replacement of the multifunction switch and a repair procedure to correct the potential loss of Generic Electronic Module (GEM) operation. Depending on the individual vehicle's GEM repair history and vehicle options, some Explorer/Mountaineer (A4WD) vehicles may be included in ONP 00B40 and not in Safety Recall 00S04. PLEASE CHECK OASIS TO DETERMINE WHICH PROGRAM APPLIES TO A PARTICULAR VEHICLE.

NOTE: Some vehicle lines not included in this owner notification program may exhibit concerns where the wipers briefly turn on with the wiper switch in the "off" position. Please consult OASIS for the latest technical information pertaining to those vehicle lines.

SERVICE ACTION
Dealers will replace the multifunction switch on all affected vehicles. The replacement switch has a revised design.

- NOTE 1: Explorer, Mountaineer and Ranger 4X2 vehicles without power windows are not involved in this program. Please consult OASIS for the latest technical information pertaining to those vehicles.
- NOTE 2: Many vehicles have previously had the multifunction switch replaced under warranty. These vehicles are not included in this program.
- NOTE 3: Owner Notification Program 00B40 supercedes TSB 99-24-03 for Explorer, Mountaineer, Ranger, Expedition, Navigator and Villager vehicles. The revised multifunction switch used in this ONP eliminates the need for Generic Electronic Module (GEM) replacement as previously described in the TSB.

I was thinking multifunction switch, but my high beam works. does this mean it's not the multifunction because one aspect of it works?

??

No, each function in that switch will have its own wiring and contacts.

a multifunction switch is $120 and can't be returned so I'm trying to make sure that's the most likely suspect.

could it be a relay? although I wouldn't think the signals and wipers would be on the same one.


a friend suggested it could be the clockspring. I'm not sure what this is

Under the steering wheel is a very long group of wires, used for the horn, cruise control and other buttons on the steering wheel.
This long wire is wound around the steering column and looks like an old Clock Spring on a wind up clock, this "clock spring" wire allows you to turn the steering wheel without the buttons on the steering wheel being disconnected.

Clock spring wire would not be connected to wipers, brake lights or turn signal since since none of those are buttons on the steering wheel.

Your problem might not be the multifunction switch, just the wires or connectors.

Maybe, could have melted connector or wire just hanging on by a thread.
If you have an volt/ohm meter you can test the connections with the switch in various positions.

Yes, that is normal, those fuses are between light bulbs and multi-switch, they are there in case the longer wires get a short or the trailer lights if connected short out.

thanks, a friend said 1 side of the fuse should always be live. I obviously don't have a clue

On most fuses that is true, there are fuses that have power all the time on one side, and fuses that only have power when key is in a certain position, i.e. Accessory, RUN or START
And there are fuses like the ones you tested that only have power when a specific system is activated.
The later is there so you don't loses brake lights if there is a short, because the main fuse feeding that circuit would blow.
And if you lose brake light power on newer vehicles and have an automatic you often can't shift out of Park because there is a solenoid that must be activated to release "shift lock" by putting your foot on the brake pedal, which activates brake lights and solenoid
