SamZman Posted February 10, 2005 Report Share Posted February 10, 2005 My windshield wipers have been acting up on my 91 Mustang GT. First they just work periodically, then hardly at all...then REALLY slow.. I noticed in the past that my headlights wouldnt work unless I flashed my brights on and off.. so I thought I'd replaced the turn signal lever. Well my headlights work fine but the wiper problem is still there. When changing the switch out I noticed the wiring harness for the wipers that plugged into the turn signal lever looked a little fried. I dont even know if this is replacable.. It seemed to connect fine and the wipers still work periodically but slower and slower.. This sound like a wiper motor? I've been trying to find out if this is common, but I'm guessing not.. the wiper motor is 80 bucks so I dont wanna just try it out.. I'm gonna try to test the motor this weekend and take another look at the harness.. just wanted to see if anyone had any suggestions before I start w/ it again.. Thanks..

Alex1647545498 Posted February 10, 2005 Report Share Posted February 10, 2005 The switch just does on and off so if it's getting slower and slower it's most likely the motor or the power supply. You can try taking a multimeter to where the motor is getting power and find out how much power it is getting. Then check with a manual or some online source on how much voltage it should be getting. Even though it's 80 bucks, you can return it if that's not the problem. They ususally give you a time frame where you can return items.

Dave1647545494 Posted February 10, 2005 Report Share Posted February 10, 2005 if you can find a stang in the junkyard you might be able to get the harness out of the colum, its easier to replace the whole colum though. I would do what alex said and ohm out the wiper motor first its prolly shot. Quote Link to comment Share on other sites More sharing options...
ridenred27 Posted February 11, 2005 Report Share Posted February 11, 2005 make sure that you inspect the ignition switch very carefully. fords of that era were known for the switch to overheat and melt the surrounding wires. Quote Link to comment Share on other sites More sharing options...
Guest Harris92 Posted February 11, 2005 Report Share Posted February 11, 2005 Have you checked battery power, alternator,etc? If you are getting full battery power, then it sure sounds like the wiper motor. Quote Link to comment Share on other sites More sharing options...
Clifford Automotive Posted February 11, 2005 Report Share Posted February 11, 2005 90 PERCENT OF THE TIME ON ANY VEHICLE WHEN YOU START HAVING PROBLEMS WITH WIPERS ITS THE MOTOR NOT THE SWITCH. ID LOOK INTO A NEW MOTOR FOR IT. Quote Link to comment Share on other sites More sharing options...
stolen 5.0 Posted February 11, 2005 Report Share Posted February 11, 2005 happend to mine sam. wipers stopped working and then started a few times. then got slower, then quiet on me on the way to cbus one day in pouring down rain. had to pull over in zanesville and change it outside a napa. do urself a favor and change the motor before u get stuck in the rain. easy to do also Quote Link to comment Share on other sites More sharing options...
SamZman Posted February 12, 2005 Author Report Share Posted February 12, 2005 Thanks for all the input guys. graemlins/thumb.gif .. I ended up just putting a motor in , and sure enough that was the problem. Only reason I didnt just do that when it first happened was the other problems fooled me into thinkin it was somethin else... and Auto Zone said they wouldnt take it back once it was installed.. Anyways. All is good. smile.gif Thanks again everyone. Quote Link to comment Share on other sites More sharing options...

Which is why you always tell them you never installed the item. Their rules are meant to be broken. tongue.gif Quote Link to comment Share on other sites More sharing options...
