My windshield washer sprayer has been giving me trouble for the past two or three years. My mechanic has replaced the motor. Then I brought it back two times after it stopped working agian. But it worked when they tested it.
Now it is finally really dyeing. It has only rearly worked for minuets at a time for the last week. It is pretty cold out now though so I don't want to spend hours pulling everything appart outside in the snow.
I think it might be the combination windshield whipers/washer switch in the dashboard. The wiper part still works fine though. Should I get a new switch? Or is there somthing else I should be checking into?
three possibilities for INTERMITTENT washer functions on a bronco depending on year, possibility #1, obviously the pump, #2 the washer switch itself, and #3 there is a level indicator in the fluid tank that will shut down the system if the tank is empty (this was problem in mine) to prevent pump from running dry. Easiest way to narrow down problem is when problem is occuring have someone hold washer switch on, check for 12V at pump, if you do have voltage at pump, replace pump assy, if no voltage, unplug the level indicator plug (from bottom of coolant/washer tank) and put a short across plug, then check for 12v again, if still no voltage, check switch and associated wiring. (note: just because windshield wipers come on when you press washer switch, do NOT automatically assume switch is good, it is a dual switch and half could be bad).
Okay thanks for the insight. I didn't realize there was a fluid level sensor there too. I'll check it out using your methoid before plucking down the money on a new switch.
There's a 4th possibility, and I have a feeling that the Goat's car has that one, especially because I have the same problem, and diagnosed it beyond any doubt. The problem is with the connector that plugs into the tank and onto the washer motor's plugs. The jacks in that connector are just 2 thin pieces of copper rolled around to form an "O" embedded in some hard rubber, and over time they get loose and won't make a good connect. I already tried the stealership -- they could sell me some complete wiring harness, but not the connector itself. I also did some extensive online search, but came up empty handed. There's no fix (other than the complete harness) as far as I know, but there are various bandaids or hacks ( ) to get the pump working.
That was the problem with mine, not the sensor itself, but the connecter that plugs into the side of the washer fluid tank got coolant/washer fluid in it, and corroded it, a little contact cleaner, and silicone dielectric grease took care of it. The hardest part was reproducing the problem, since it was so intermittent, every time I popped the hood to test it, it started working again. However thats why I mentioned unplugging it and shorting the level sensor out to rule that out as a possibility.

Had this same problem and cause with my '88 Ranger pickup from day one. Intermittant at first so of course always worked when I took it in for warranty, but eventually quit working. I think I spliced in 3 or 4 used plugins from upullit. Just another little built in FORD headache .
If you are handy with a soldering iron, there are ways to fix this problem for good by changing the OEM connector to a different (more reliable) two-wire connector. I've done it to two Ford pump assemblies that have had a similar breakdown in conductivity.
Thing is, that connector has several functions:
a) it transmits power to the washer motor
b) seals out water and dirt
c) stays in place
d) removable (even if it's a pain to do that )
Getting 3 out of 4 isn't that difficult, but getting all 4 properly without a correct connector is a bit tricky, at the very least. IMHO, the design is defective, either they should've used a blade type connector, or thicker plugs for more lasting contact.

It looks like my problem is with the connector like you guys are talking about. Pressing the button on the dashbord lights up my testlight pleanty bright. And I did get the sprayer to work just now after giggling the connector arround. Where can I get a better two wire connector? I can solder a new one on no problem.
Also I looked for the water level sensor illuzion was talking about but I couldn't find it. Am I correct in assuming ford only added this feature after my model year? (which is 1990 as far as I know)

Just a thought, but has anybody ever tried useing pliers and squeezing the loose "O" contacts into an "0"? (O => 0) As long as you can still get the connector on the motor's terminals it shoud help make better contact.
A Simular problem happened with the connector on top of my starter relay. I just crimped it tighter and rammed it on the relay and it has started every time since. I'm too scared to try on my bronco right now. The sprayer is working for now (maybee not, I probably broke the connection when I closed the door).
Hehehe, I've been doing that for a while, but after a couple of months (at most) they fail again.
What I'm trying to do is to put a very thin copper sleeve over the two plugs, but finding that in the right size is also not easy. If you don't care about water or dirt getting in there, you can use many other connectors without much problem.
Dont want to hi-jack this post, but would anyone know why in my resovior, the side that you pure the washer fluid into does not spill over to the side that feeds it out to the spray nosel? Basicly one side of my resovoir fills and the other does not, and the one side is filled to the top. and the other side is bone dry.

Well the sprayer wasn't working agian this morrning. So just now after getting home from work I pulled my "squeeze with pliers" trick. It started working agian. I'll see what happens tomarrow. If the pliers trick works for the net three or four months I'll be happy. Then I can spend time fixing it right when it is warmer.
