When I started the 1995 Ranger to leave for work, and run the wipers. The wipers are not working.
I read an article where you can take the end of the wiper switch, and clean out the inside.I got mine cleaned up, but didn't see any small spring, till I seen it laying on the floor mat. I didn't even see it before. I could only find one of those brass ends for it though, and I didn't get to see where it goes in at?
Will it work with only one brass end?

Any ideas, with pictures?

You will probably need to buy a new Multi-function switch, if parts are now missing

1995 to 1998 Rangers/Mazda B-series and Explorers used the same unit

 

Got a new wiper switch put in, and did not work. I decided to clean off the battery terminals, and then it worked for a day. Now it is not working again?
Any thoughts, ideas, or suggestions?

 

Does the washer squirt fluid?

When they worked did they Park OK when you shut wipers off?

Check fuse 16, 30amp, in cab fuse box again

Cleaning battery terminals would have had no direct effect on wipers unless several other systems were also not working because of low voltage

There are two wiper relays in engine fuse box, unplug and plug back in both to clean connections

Ultimately it could be the wiper motor itself, DC electric motors can be intermittent, tap on the motor and see if wipers start working

Wipers have 3 parts
Multi-function switch
GEM Module
Wiper motor

 

The washer did squirt fluid.
The wipers parked ok.
Fuse was good.
I tried other spare relays.
I tapped on the motor with the wiper switch on, and not working.

Hazards work, high/low beam works, signal lights work.
Dome light does not come on?

 

If I pull out, and push back in the fuses under the hood, then the wipers, and dome light work, but when I go to start it, then they quit working?

Does the 1995 2.3l, RWD have the GEM module?

 

1995 thru 2003 had GEM modules.........................unless it was a Fleet Model. i.e. no radio, no power group and manual trans

 

My dome light don't work either. My mechanic said it's probably the Central timer module then?
VF57B-14B205-AE
I wonder if there could be a solder point that needs to be recooked?
About 12 minutes into it:

 

Sure, solder away, heat up any solder joints, can't hurt

There is no "test" for GEM modules

Shouldn't be a "V" at the start just F57B-14B205-AE
F5 = 1995
7=Ranger
B = department at Ford the engineered it

14B205 = Body Control Module, in ANY FORD in ANY YEAR

AE is the software, you should try to match this

Skip areas
You zipcode

New window will open
Select "Multifunction, (behind center dash), w/o remote keyless entry; ID F57B-14B205-AE"
Search

Usually about $40-$50, but depends on your area, they are light and most places will ship if its cheaper but farther away

And no, you can't add Keyless entry just by changing the GEM to another model, lol

 

I didn't see any obvious bad solder spots, but I used some MAF sensor cleaner on both the male and female connectors, and put back in.
So far it has gone two days, and all is working?

 

I cleaned it a second time and lasted one day, then quit, but I noticed when it quit, it made one ghost wipe.

Anyway, I got one from a 97 Ranger. It's working, but owner of the junk yard told me the first number represents the year, and last number indicates any upgrades.
It is working, but I noticed that this later one has that annoying chime built into it.
Is it possible to remove the chime in the circuit board??

 

Yes, you can unsolder the chime from the GEM circuit board

But which chime don't you like, if its just "Key in ignition" then you can unplug the one wire on the key slot and that will stop it
If its "headlights left on" or "Seat belts" then you will need to unsolder it

 

I got another one at the junk yard, and it worked for about 1 1/2 days, and it did the same thing. Before it quit, the wipers did a ghost wipe, when I went to start it.
Now the wipers don't work, or the dome light??

My mechanic said, it sounds like a ground issue?
I've never looked under that box in the engine bay by the firewall. Are there any connections under the box that could be getting corrided?
I did clean the battery ground again, and everything works again, for a while?
Seems like if I unhook the battery, and hook it back up, it works for a while?

Any ideas where to check the grounds, or any other things that might be causing this problem?

 

Is there a diagram that shows where all the grounds are?

I noticed the wipers/dome light will quit working when every so often go to start the engine, and the wipers do one ghost wipe, then they quit.
If I disconnect the battery, and connect it again. They work then for a while?

 

Google: 1995 Ford Ranger EVTM

Ford prints these books and sends them out with shop manual set for every model every year, so their dealer techs can work on new models
Must be 1995 and must be Ford EVTM

And they are basically Free to use, you buy it, use it, then resell it, they are always in demand

Couple of standard grounds to check
Main ground, battery negative to engine, usually starter motor bolt
Battery negative to Rad support/inner fender, smaller wire
Engine to Cab, usually back of driver's side head to firewall, a ground strap, often left off after engine work, its the Cabs MAIN GROUND, so a must have, if you can't find it add it

 

Cleaned all the grounds, and had it work for 5 days. Usually if I unhook, and hook the battery back up, it works again. This time no?
IDK, might be time to take it to the mechanic?

 

When it decides to act up, it's when I start the engine, the does one phantom wipe, and then wipers, and dome light quit.
If I unhook the battery, and hook it back up, then it works again?
Is it because something resets again, till it decides to quit? If so, what could that be?

 

GEM module(aka central timer module) is the only thing they have in common

If turning on and off the key doesn't reset it then try unplugging Fuse 25 in Cab fuse box, key off, then plug it back in and turn get on, that just rests the GEM

Fuse 25 powers GEM full time, so same as unhooking battery, if you pull it out, as far as GEM is concerned
If that works then GEM is the issue

 

I took out the fuse, and could hear it clicking when putting fuse back in, and wipers, and dome light are back on for now.

So that means the central timer module is the problem?

I replaced it about 3 weeks ago with a used one from a 97 Ranger, but who says that one might of had the same problem?

Would it be the solder points that need to be resoldered to solve the problem?

 

Yes, it is a CTM issue if removing fuse reset it

There could be a wiring issue or any number of circuit board problems causing it to "lock up"

A different GEM/CTM having the same issue is long odds
You could try pulling the fuse for the wipers if not needed for a few days, and see if dome light continues to work OK
And do opposite, pull dome light fuse and see if wipers stay working

Not sure what the issue might be???

Also check if it resets with key on, i.e. if wiper quit working don't shut off the key, just pull fuse 25 and put it back in and see if it resets

 

Wipers done their phantom wipe today, and so while in the act, I left the engine running, and pulled out, and put back in fuse 25.
I then shut the engine off, and started it again, and started working again. At that point, I also put back in the dome light fuse, and it's working at this point.

My mechanic still thinks it's a ground issue?

Is there a ground on the wiper motor, and how hard is it to get to, to clean it??

Also, the manual gives the location of GEM, as 10, 20, and 27?

 

The 1 wipe is the GEM sending a 12v pulse to the wiper relay, that activate Park 12volts so wiper motor completes one pass of the wipers, same is used for intermittent wipers

Not sure a ground could effect both or even a GEM ground

 

I think I'm lost as what to do next.

Why is it that if it is going to not work right, it only acts up when you go to start it?

 

where is the ground for the wiper motor located?

 

On the wiper motor, or near it on firewall
