i checked the fuse panel and it appears these use the same fuse. could one be working and the other not? there is fluid in the washer tank. i dont even hear it coming on when i hit the button. I am going to change the fuse but was curious if anyone had any insite otherwise? the wiring to the washer tank looks good and hooked up properly still.

thanks

Susbscribing.... I have the same problem. Mine worked great until I removed the washer fluid resevoir to do something (change the parking lamps, maybe?) Since then the washer doesn't work. Does the pump need to be primed?

Wiper Testing '92-up Testing Diagram & Instructions in 92-96; "...There is no testing for the WCM - you test the MFS, the wiper & spray motors, and the wiring. If they're good but don't operate, it has to be the WCM by elimination..."

From 1996 Bronco Workshop Manual:
Check connector pin Numbers for your yr.
Windshield Wipers Inoperative � All Control Switch Positions
Blown fuse.
Windshield wiper motor.
Multi-function switch.
Bent or damaged windshield wiper motor linkage.
Wiper control module.
Open wire or connector.

PINPOINT TEST B: WINDSHIELD WIPERS INOPERATIVE� ALL SWITCH POSITIONS

B1 CHECK FOR SUPPLY VOLTAGE AT MOTOR
Key to RUN.
Turn multi-function switch to HI.
Unplug windshield wiper motor.
Check for battery voltage at Circuit 65 (DG).
Is battery voltage present?
Yes GO to B2.
No CHECK for open fuse. REPLACE fuse. If fuse fails again, SERVICE B+ short to ground in Circuit 65 (DG). RETEST system.

B2 CHECK FOR BATTERY VOLTAGE AT THE WINDSHIELD WIPER CONTROL MODULE
Check for battery voltage at Circuit 65 (DG) Pins 2 and 11 of connector.
Is battery voltage present?
Yes GO to B3.
No SERVICE open in power feed to windshield wiper control module.

B3 CHECK FOR BATTERY VOLTAGE TO MOTOR WINDINGS
Key to RUN.
Turn multi-function switch to HI.
Disconnect connector from windshield wiper motor.
Check for battery voltage between Circuits 61 (Y/R) and 58 (W).
Is battery voltage present?
Yes REPLACE wiper motor.
No GO to B4.

B4 CHECK FOR BATTERY VOLTAGE AT WINDSHIELD WIPER CONTROL MODULE CONNECTOR
Check for battery voltage between Pin 10 Circuit 61 (Y/R) and Pin 14 Circuit 58 (W) of windshield wiper control module connector.
Is battery voltage present?
Yes CHECK for:
Open wire Circuits 58 (W) or 61 (Y/R).
Unseated terminals.
No GO to B5.

B5 CHECK WIRING BETWEEN WINDSHIELD WIPER CONTROL MODULE AND MULTI-FUNCTION SWITCH
Disconnect connector from windshield wiper control module and column connector to switch.
Measure resistance between Circuits 993 (BR/W) and 589 (O) with multi-function switch at HI.
Is resistance less than 5 ohm?
Yes REPLACE wiper control module.
No GO to B6.

B6 CHECK WIPER SWITCH CONTINUITY
Disconnect multi-function switch harness at steering column.
Check continuity between terminals 1 and 4 with switch at HI in on position.
Is resistance less than 1 ohm?
Yes CHECK for open wire between multi-function switch and wiper control module. SERVICE as required.
No REPLACE multi-function switch.


Check CKT BREAKER 2 in can fuse block - for Interval Wiper/Washer, 8.25 amps

check for power on Feed side from Maxi Fuse P in PDB
Verify Fuse and Maxi Fuse by using your Fuse Block cover legend; Ford messed legend up in my 96 or Ford's printer did... it does not agree w/on-line diagram such as Steve's or my EVTM



Fuse & PBD Diagram in 93 by Steve83 - should be = to your yr



btw, I was AlM in that FTE place until K got his panties twisted because I ref my broncolinks.com site ONCE; he e mailed me for a week, accusing me of "spamming fte".. it was really because I had a Parts site and someone said he was poed because It showed parts sources other than his $ scam.

The pump on the bottom of the reservoir goes bad, happened to my '96. Seems to me it was a $10-$15 part. Takes more time to drain/pull the reservoir than to replace the pump.
Pull the plug on the pump, check for voltage.

:stupid

Unplug the pump, test the wires, replace with a new pump, done!

I had a similar problem and took it in to a friend of mine that works at a ford dealer....He had to replace a multi-function switch and it fixed it for me.
