Question about 2001 Mercury Sable

2 Answers

Intermittent wiper malfunction, 2004 Sable

Wipers functions fine at normal, continuous and high speed operation other than when I turn them off. They do not "park" in the normal full down position when turned off. I must hit the turn off switch at the exact moment to get them stopped in the full down postion. The intermittent function starts but then quits after the wiper has traveled less than a full cycle of the windshield. I have to go to full, normal operation and then turn it off at the right moment to get it "parked" correctly. The wiper function switch feels okay and seems to function correctly. Where do I look to resolve this problem. Thanks for your help.

    Have tried unsuccessfully to get the suggested wiper relay to determine if it will resolve my problem. My favorite parts store couldn't supply it and my local Ford/Mercury dealer couldn't determine which part I need with me actually removing the part and bringing it to him. Sad. I'll let you know how this works out.

    Finally obtained and installed a replacement wiper relay. It didn't solve the problem. No change in the problematic operation of the wipers as outlined in my original message. What should I check out next?

    Thanks much,

    Uplon a second, more complete look at my 2004 Mercury Sable Owners manual, I noted that there are two wiper relays; one for wiper speed and a second for wiper park. I purchased a second relay (they both have the same Ford part number) and everything worked fine (for about 6 hours). This period involved use of the wipers in both intermediate and full cycle mode. Everything worked fine until I turned on the windshield washers. From that point on, the original problem reappeared. A puzzle.

    It was the wiper motor. Had it replaced and all is well. Thanks for your help.

My son had the identical problem on his Ford Taurus and changing the wiper MOTOR which determines the park position cured the problem.

    Next the park sense in the motor could be malfunctioning. This is only correctable by replacing the wiper motor. Which is why i had you check the relay first. Also look into the governor some models have governors on them that can cause this same problem.

My wiper motor only works on high and stops were ever the wipers are at. And the washer motor doest #39;t work

Low Speed Windshield Wipers
Low speed is activated when the multifunction switch supplies a specific ground to the speed inputs of the windshield wiper motor module. The windshield wiper motor module then supplies ground to only the windshield wiper run/park relay coil, activating it. When the windshield wiper run/park relay is activated, the deactivated high/low relay connects voltage to the windshield wiper motor low input activating the wiper motor. The windshield wiper motor module continues to operate the windshield wiper motor in the same manner as in high speed, but in low speed with the wiper motor connected to the low speed input.
Washer System
The windshield washer is activated by the internal wiper motor module when it receives a ground signal input from the multifunction switch. Dependent on the switch selection, the internal wiper motor module activates the windshield washer relay (internal) by grounding the respective relay coil. When the relay is activated, it connects voltage to the washer pump while the washer level switch provides ground to the washer pump.

    Does the turn signal switch operate wind shield wipers 2001 f 150 7 wire need diagram

    this is not a normal application as with washers/wipers there are multiple operations on the stalk ( up for 1 swipe- neutral /off-down 1 intermittent speed -down again 2 intermittenent wipes --3 on all the time Twist the knob of time period of swipes during intermittent swipes.. Turn switches indicate l or r ( up or down) and back to the wheel high or low beam for the head lights or twist the knob for off parks and headlights.

    What is the relay location in the relay box

    The problem would be in the stalk controller. The wiper Relay is what provides power to the motor for all settings, the delayed wipers, low speed, and high speed. There are not 3 relays, but 1 for all functions. If you have power to the high setting, the relay is working.

    Wipers don't work in high speed and when intermittent wipers are set they stop in the middle of the windshield.

    Yes that is likely a switch problem. Before you buy any parts have a shop confirm my guess.

    Windshield wipers go full speed on intermittent setting

    Sounds to me like the person you talked to was probably just a service writer who has no clue. That would either be a body control module malfunction, or a bad wiper switch. The wiper switch would be a more likely cause.

    Wipers do not work in intermittent position. They do work in low and high speeds but do not automatically return to the park position. They stop wherever you turn the switch off.

    i belive that your wiper switch has gone out on the intermittent side. this is a very common problem.
    I hope this helps you
