So for some reason I guess I assumed it was normal that my wipers did not return to the down position when I turn them off, they just stop moving wherever they are. I figured eh my car came as a base model it probably did not have that feature, just like how I only have 2 wiper settings.
Recently my car repaired itself and the wipers return to the down position by themselves when I turn the wipers off.
A week later and it stopped working again.
So, the control module is on the wiper motor correct? (85 fiero)
And if I replace it, can I upgrade to the wiper stalk and motor that allow intermittent wiper settings? Or will I have to change some wiring as well?
1, It sounds like the "park" switch in the wiper motor is either failing OR the wiper switch in the steering column is bad. If it's the park switch, you will need a new wiper motor as the park switch is not available separately. If it's the wiper switch, you will need to open the steering column to replace it. It's possible the wiper switch isn't always sending the signal to the park switch, telling the wipers to return home...so to speak. Because it wasn't working but now is, I would start by checking for a bad connection before replacing anything. Check the connections at the wiring harness for the wiper switch under the dash at the base of the steering column. Check the wires at the wiper switch and especially the ground at the wiper switch (one of the three bolts that holds the motor to the bulk head acts as the ground). If all connections are solid and clean. Now you've gotta narrow it to the park or wiper switch. Try wiggling the turn signal lever while shutting the wipers off to see if you can replicate a faulty wiper switch.
2, Different wiper switches for standard wipers v. intermittent wipers. If you are planning to upgrade to intermittent wipers, you will need top replace three things. 1, Wiper motor. 2, wiper switch in the steering column. 3, turn signal stalk. All three items are unique to intermittent wipers or Delay wipers, which ever you want to call them. If you're going to upgrade, no need to diagnose the parking issue.
The only wiper motor with a replaceable module is the "intermittent" style motor. You can compare a photo of the two on www.rockauto.com.
Unfortunately, you do have to tear the column down to the switch and then fish the harness down. I'm assuming that since you don't have the delay wipers that you prob. don't have a tilt column either. If no tilt, it's a little less work to replace. Still a chore the 1st time.
Well, depending on your experience, it may be better to get the switch and have a shop install it. Where I used to work we charged $100 to tighten a loose GM tilt column. That's tearing it down farther than you have to do for the switch. 30 minutes for a knowledgable tech v. possibly all weekend for you or me!
