Could anyone explain to me how to adjust the wiper motor such that the wipers go all the way down to park position. It needs to go about another 1 to 1.5 inches more down. This is on a 71 cutlass.

Did you recently replace the WWiper motor assembly?

 

Did they ever go all the way down since you have owned the car?

 

Remove (carefully so you don't scratch any paint) the arms from the splines and re-mount them a few degrees toward the bottom.

 

That might work on a 66 Cutlass, but not on a 71. The driver side is a double arm that will only go in one position. I can tell you how to do it, but before that, I want to know if they EVER went down. I think that's why Alan asked if the motor was changed. There are motors out there that look right, but they don't have the ability to retract the wipers. I spent a long time trying to adjust mine to park on a car I bought, only to find out it was a Chevy truck motor that looked perfect, but would never retract the wipers.

 

Oops, that's what happens when you assume...... sorry about that.

 

Yes, I did replace the wiper motor. When I got the car, it had wrong type of wiper motor. It did not have a park position. They always were on the windshield. Got the right motor that lowers the wiper to their parked position below the windshield. Since installing, it never did go all the way down, but good enough compared to what I had... So I was happy. But now it is starting to bug me. They should go down a little bit farther. I lost the install instruction which I recall did talk about adjusting it to get them in the parked position. So, maybe one of you remember how to adjust it. MrOlds69 is right. The wipers can only be mounted one way. No spline on these. Sounds like MrOlds69 knows they type I have. Please let me know how to adjust this motor.

 

You are right. Please see my last post. I did replace the unit. Need to know how to adjust now.

 

There is an extensive section on proper operation and troubleshooting in the...

Chassis Service Manual

Surely you have at least ONE, right?

 

Do you have a Fisher Body Manual for your car? Your problem is described with great pics and text on Page 2-24. Here's the text part if you need it.

1. Raise hood and remove cowl vent screen
2. Remove the right arm and blade assembly
3. Loosen but do not remove the transmission drive link to the motor crank arm attaching nuts.
4. Rotate the left arm assembly to a position 1" below where the blade stops.
5. Tighten the attaching nuts on the transmission drive links to motor crankarm (19-29 in lbs)
6. Position the right arm and blade assembly 1" below the blade stop and install arm assembly to transmission shaft.
7. Lift the right and left arm and blade assemblies of the the stops.
8. Test for wipe pattern and park position. You car should be 1.61" - plus 1.1" or minus .5"
9. Reinstall cowl vent screen

NOTE: determine correct park position and outwipe dimension with wipers operating at Lo speed on WET glass.

 

What Allan wrote is how you do it. That procedure assumes everything on the car is right. I'm curious, did that work for you?

 

Yea... that worked just fine. I feel dumb now. That was such a simple and obvious adjustment. Do not know how come I did not see that.

Thanks for everyone's help

 

Good deal, glad it's fixed! It's very common to see that, don't feel bad.

 

I wouldn't feel dumb at all asking for help. I do however recommend a copy of the Assembly Manual, Fisher Body Manual and Chassis Service Manual if you plan to keep the car. Usually the stuff you don't find in the CSM is covered in the FB manual or AM. Hopefully it's all smooth sailing now - top down and punch it. LOL - just no driving in the rain now and it's golden!
