1987 Cadillac Fleetwood. The wipers work fine yet every time I push the fluid button nothing is sprayed out the wipers run yet no fluid comes out. I filled the reservoir and also noticed this tube floating around inside. Can anybody tell me what's wrong.

Take that filter out on the end of the tube and wash it out real good. Look for pinched/damaged hoses as well. Also take out the washer nossles(the part that sprays the windshield) and run some compressed air through them.

I had the same problem on my 1991, everything was just clogged with junk, preventing the flow of fluid. If that doesn't help, you might have to replace the washer fluid pump, its mounted up on the firewall, was $30 from O'Riellys. I ended up returning the pump.

How about that thing that was floating in the reservoir? The thing I'm holding.

i always thought the fluid pump on these cars were part of the wiper motor assembly.

Blew some air through the hoses and washer fluid sprayed the mirror so I can tell they work yet whenever I enable the wash no spay comes out, and I don't see the filter running or taking out any fluid.

Hello

If the car is a 1987 (fleetwood) Brougham. Then the washer pump is a part of the wiper motor assembly as gdorell wrote.
If the car is a front wheel drive Fleetwood, I have no idea how the washer works on that model.
But since we are on the Rear wheel drive forum I guess that the car is a Brougham.

The thing you hold in your hand is the thing that should float in the fluid and warn when the fluid is low.
I dont know how it come loose but something have happend there. The thing should be mounted on the white pipe, above the filter and under the cap, probably have the filter or the whole white pipe come loose in the resvoir and loose the floater inside.

The washer pump is a tiny membrane pump mounted on the wiper motor assambly, driven by the wiper motor via a cam.
When you press the washer button, a little electro magnet inside the wiper assembly, moves some little levers there. The wipers also starts.
The levers do so when the wiper starts, a plastic wheel follow the wipers and is moved about a quarter turn every stroke the wiper go, and presses on the washer membranepump at every stroke also.
When the plastic wheel has turned a complete lap the wiper should stop and go back to park.

The most common problems with these washers is dryed out hoses, very important that no air is sucked, because if there is air beeing sucked the pump will not be able to suck the water from the resevoir.
It is also very important that there is a one way valve at the filter. Your filter seams to have been around, so check that.
If the membran in the pump is broken, there is repair kits for that.

I hope you understands most of what I have tried to write, it is difficult to find the right words when i dont use english on a daily basis.

I have the repair procedure for the rear wheel drive Brougham. The first thing you have to do is buy a 12 volt test lamp. They're available at most auto parts stores or in the automotive tool section of Sears hardware.

The diagnosis and repair procedure is as follows:
1. Check the washer system for water in reservoir, pinched/kinked hoses, loose hose attachments, plugged screen, or plugged nozzles. If there are problems repair accordingly, otherwise continue. (Note: the following steps require the ignition switch to be in the run position)

2. Backprobe WIPER/WASHER ASSEMBLY (which in the center of the firewall, in the engine compartment) connector C2 (which is connector on the front of the assembly) with a test lamp from cavity B (they should be in alphabetical order from left to right) to chassis ground. Turn ignition switch to run. If the test lamp doesn't light, the white wire that runs from the fuse block to the assembly is broken. If the test lamp lights, continue

3. Disconnect connector C2. Disconnect WIPER/WASHER CONTROL connector (which is the switch on the dash, and is a bitch to get out). Connect a fused jumper (you might have to make this) from connector the wiper/washer control connector cavity C to chassis ground. connect a test lamp from connector C2 cavity B to C2 cavity A. If the test lamp does not light, the pink wire that runs from the wiper/washer assembly to the control connector is broken. If the lamp lights, continue.

4. Connect a test lamp to from wiper/washer assembly connector C2 cavity B to wiper/washer control connector cavity B. If the test lamp doesn't light, repair the black ground wire for the wiper/washer control connector. If the light illuminates, reconnect the assembly connector C2 and continue.

5. Connect a fused jumper from wiper/washer control connector cavity C to chassis ground. If the washers operate, replace the wiper/washer control. If the washers don't operate, reconnect the control connector and continue.

6. Backprobe wiper/washer connector C2 with a test lamp from cavity A to chassis ground. If the lamp does not light, replace washer relay. If the lamp lights, continue.

7. Remove the washer pump cover. Turn wiper/washer control to LO. Observe ratchet pawl. If the ratchet pawl does not move, replace the washer pump assembly. If it does move, continue.

8. Press the washer switch and check ratchet gear operation. If the ratchet gear rotates, replace the valve assembly and retest system, if problem still exists, replace pistons and pump assembly. If the ratchet gear doesn't rotate, check for ratchet pawl spring missing or not properly connected, ratchet dog spring not engaging ratchet gear teeth.

9. Disconnect wiper/washer assembly connector C2. Disconnect wiper/washer control connector. connect a test lamp from C2 cavity B to cavity A. If the lamp lights, there is a short to ground in the pink wire, mentioned above. If the lamp doesn't light, leave it connected and continue.

10. Reconnect the control connector. DO NOT press the washer switch. If the lamp lights, replace the wiper washer control. If the lamp doesn't light, reconnect C2 and continue.

11. Remove washer pump cover. Check position of the armature leg. If the armature leg has lipped off the ratchet gear, check for dog spring not engaging ratchet gear teeth, worn ratchet gear teeth, worn ratchet gear spring tooth, and ratchet pawl spring missing or not properly installed. Replace parts as required. If the armature leg is in the correct position, check for loose pole pieces on washer relay or burr on end armature leg. replace parts as required.

I highly recommend to you and anyone who is planning on repairing their Cadillac themselves, that they acquire the factory service manual. Here are some on eBay for an 87 brougham (http://shop.ebay.com/items/_W0QQ_dmptZMotorsQ5fManualsQ5fLiterature?_nkw=1987 +cadillac+brougham+repair+manual&_sacat=0&_fromfsb=&_trksid=m270.l1313&_odkw=1987+cadillac+repair+manual&_osacat=0). I got all of this information from my OEM service manual, for an 89 Brougham, so some of the wire colors may be different.
