My wipers wont park. It seems most have replaced the motor. Does anyone know how to diagnose if motor or module. Wipers work ok most of time. Just wont park under cowl. Sometimes when I hit mist wipers wont work, then after delay of about 10 seconds I get one swipe.

Thanks, Walt
 
RE: Wipers wont park Gen 2

I don't honestly know if there is any sure way to diagnose whether it's the motor or the module. If it was me, I'd replace the motor first, BUT if you get a rebuilt, make sure that it comes with the parking mechanism attached. I tried replacing my motor a while back, and it didn't come with the parking mechanism. It didn't fix the problem. Out of frustration I took it to the dealer, where they told me that BOTH the motor and module needed to be replaced. It works now, but I have the feeling I could have gotten away with just the motor.

NAPA told me that the motor didn't come with the parking assembly, but a few others here said their's (from NAPA) came with it. Go figure.

Sorry, I know that's not much help.
 
RE: Wipers wont park Gen 2

The manual has literally pages of diagnostic tests. Here is a pertinent section...

Parking Test


Tool Required:

> Rotunda Digital Volt-Ohmmeter 014-00407

The ignition switch must be in RUN position for all tests. Verify proper operation of wiper system in low speed. With system operating in LO, turn wiper system switch to OFF when wiper blades are in vertical (straight-up) position. Wipers should complete cycle and depress park (below windshield). If wiper blades do not park, locate the system's condition on the list below and test and service as indicated.

> Motor stops when wiper switch is turned to OFF. (Does not complete cycle).

1. Remove motor park switch connector and check for battery voltage, using Rotunda Digital Volt-Ohmmeter 014-00407 or equivalent, on Circuit 65 (dark green). If battery voltage is not present, service circuit as required. If voltage is present, go to Step 2.

2. Check motor ground wiring at switch connector.

3. With both wiper motor connectors disconnected, use an ohmmeter, such as Rotunda Digital Volt-Ohmmeter 014-00407 or equivalent, to verify continuity (less than one ohm) between circuits 28 and 56 in wiring harness. If continuity is not present, trace and service as required. If continuity is OK, leave connectors disconnected and go to Step 4.

4. Check for continuity to ground terminal on gear cover at circuit terminal 28 on wiper motor. If open, replace wiper motor. If ground is present, leave connectors disconnected and go the Step 5.

5. Verify continuity (less than one ohm resistance) between Circuits 61 and 63 in wiring harness. If continuity is not present, trace and service as required. If lack of continuity is traced to interval governor, check wiper switch for continuity. Refer to «Section 11-05». Replace switch if continuity is not present. If continuity is present in switch, and lack of continuity has been traced to control module, replace module. If continuity between Circuits 61 and 63 is OK, leave connectors disconnected and go to Step 6.

6. Check for continuity between circuit terminals 63 and 65 on wiper motor. If open, replace motor.

> Wiper blades go into depressed park (below windshield), but wiper motor keeps running. Replace motor.

> Wiper blades stall or jam (motor starts running in reverse direction) while going from park to depressed park (below windshield).

1. Check linkage and service as required. If OK, go to Step 2.

2. Check wiper motor arms and windlatch assembly. If bent or cracked, replace wiper motor.

> Wiper blades complete cycle, but continue to wipe for part of another cycle and park on windshield, or

> Wiper blades run continuously when switch is in OFF or INT position, or

> Wiper blades run to bottom of windshield and stop, but will not depress park below windshield.

1. «Perform Wiper Switch Continuity Test» 'Refer to «Section 11-05». If continuity test fails, replace switch. If continuity test is OK on interval wiper system go to Step 2.

2. Check wash circuit 941 for no voltage. If any voltage is present, service as required. If no voltage is present, go to Step 3.

3. Disconnect connectors at wiper motor and check for continuity between Circuits 61 and 63 going to control module. If open, replace control module. If continuity is present, replace motor.
 
RE: Wipers wont park Gen 2

Its kinda funny,i reads these post's and then walla it happens to mine.Just got back from driving around 800 miles most of it in the rain,and today my wipers are doing the same thing::roll:: I will keep posted on this.My thought is to take out the motor and make sure all connections are clean,seems like it is just gunked up with somthing.
 
RE: Wipers wont park Gen 2

Driller,

Thanks for the info. Will update on results. Probably later this week.

RE: Wipers wont park Gen 2

Ok, just finished the wiper motor install.Got the napa motor for $92.00 before core return,no good because it did nto come with the park assembly and the one on mine was toast soooooo I called up Lincoln and went and got thiers for $211.00 with tax and after core.The Ford part comes complete and went right back in and works like a champ. Tools needed 7,8,10mm sockets and a philips and flat head and about 30 minutes or more.car is a 98 lsc with only 40,000 milesxo
 
RE: Wipers wont park Gen 2

$211!! Two years ago, I got one from napa for $50-$60 WITH the park assembly.
 
RE: Wipers wont park Gen 2

Hi gang,

I need to replace my wiper motor. Below are pics of the part that NAPA lists for the '95 Mark. Is the mysterious "park mechanism" present in these pics? If not, could someone PLEASE post a pic of what the motor+park mechanism looks like? Driving in Portland in the wintertime without properly functioning wipers is...ahem...interesting.

Thanks!!

Ditto. Except it was about 3 years ago now, and i think it was Advance auto parts.
 
RE: Wipers wont park Gen 2

Well, since no one confirmed whether the pics I posted above contain the 'park' mechanism, I bought a replacement from Ford.

Part # F7LZ-17508-AA
Cost: $206

This part definitely comes with more stuff than the NAPA one pictured above - a bracket, foam insulators and what I'm guessing is the "park" mechanism.
 
RE: Wipers wont park Gen 2

I had this problem and other electrical gremlins when I was leaving the car in the garage for weeks at a time with the battery disconnected. My wipers would work intermittently and would not park.

I took it to the dealer and they told me it needed a new column switch assembly and a new motor. They only had the switch assembly in stock so they replaced that and ordered a new motor. The new switch assembly did nothing. That night I drove the car for 1 1/2 hrs in the rain after playing with them enough to get them to work. After they started working, I didn't touch the switch again. After that they have worked great and they always park?!?!

That was several years ago.

RE: Wipers wont park Gen 2

Thanks JP! :)

My malfunctioning wipers that parked wherever they wanted to are no more. The new wiper motor is in and works perfectly.

BUT, I do have to say that this was the most frustrating job that I've tackled on a Mark VIII. It took me over 4 hours from start to finish, even using the exact procedure in the shop manual. I was about to walk away and drive it to the dealer in the morning, when the motor/cowl assembly miraculously slid into place (behind some seriously abused sheetmetal tabs).

I haven't had broken plastic and extra bolts/screws left over after an R&R job in a LONG time... but at least I won't have to do it again for another ten years.

Good luck if you have to do this repair - as Mr. T says, "I pity the fool!" :)
 
RE: Wipers wont park Gen 2

Did you have to R&R the harness plugs? When I did mine, the connectors on the motor assembly were different than the factory '93. Included with the motor were new pigtails to splice in place of the factory harness connectors.

[/div]

No, I did not have to change the harness plugs. I believe that's because I went with a new Motorcraft unit, as opposed to the reman "kit".

The Ford parts guy said that the new unit fits 94-98, while the reman "kit" fits 93-98. The reman kit comes with extra instructions and the pigtail.

BTW, the price difference between the new and reman unit was just $3.00. :eek:
 
RE: Wipers wont park Gen 2

Man Scott, I wish I'd seen this before you did the work. I've also been through the hell of replacing the motor myself and can attest to the what a pain in the ass it is.

What I figured out after taking the thing out four(!) times --don't ask-- is that you can remove the motor without removing that big plastic tray that it sits in. Getting that tray in and out was the most difficult part of the whole operation. After I figured that out, the job went from three hours of screaming and cussing to maybe half an hour of mild grunts.
 
RE: Wipers wont park Gen 2

That's OK, Mark. I remembered reading about your experiences with the muliple wiper motor R&Rs, so I had already steeled myself for the worst. The worst just turned out to be worse than I imagined! :)

I don't see how the wiper motor can come out without removing the whole cowl/tray assembly - but if I ever have to replace it again, you can bet that I'm gonna find out.
 
RE: Wipers wont park Gen 2

The wiper motor replacement in my gen 1 is what led me to go buy another freaking car. Then i realized i still had to fix the wipers to sell the gen 1. xo

I replaced mine in the '93 without removing the tray. PITA for sure but I've seen worse.
