This morning I used the washer fluid to clean my windshield. After that, despite being in the off position, the wipers continue to move at the slowest intermittent setting. I can speed them up to fast, but they continue on the slow intermittent speed when the swith is off. I'm not sure if it's the "phanton swipe" because it's always on. I restarted the vehicle and dis/reconnected the negative terminal of the battery with no success. Any ideas?

PS-The stupid wipers squeak too, and I don't wanna wear out new ones right away. So irritating...

 

Please let us know what you are driving (year, make, model, etc). Anything that you feel is pertinent. Wiper schematics varied throughout the years.

 

I thought i put in in my signature... Huh

Anyway it's a 1998 Chev Blazer 2dr ZR2. 185 xxx km's.

 

How many sign-ons do you have???

*EDIT* Answer was two and is now only one. Please do not create another sign-on as that is prohibited by the rules of the forum. If you have problems logging in, please email me with the email address provided in the Announcement viewable in the Forum Notice section.

 

I'm not sure. But anyway, any ideas on the problem?

 

As far as your problem goes, to determine whether there is a problem with the multifunction switch on the steering column or with the wiper motor itself, you need to test the circuit resistance per the schematic below:


You can test the multifunction switch by first removing the FRT WPR fuse from the IP fuse box (accessible by removing the cover on the driver side end of the dash with the door open). Then, with your multimeter set to read circuit resistance, probe between the C & A pins on the connector at the wiper motor. Resistance should be 24,000 Ohms whenever the wiper speed is on any one of the pulse speeds and on low speed as well. Then, testing between the C & E pins, 680 kOhms, 305 kOhms, 155 kOhms, 75 kOhms, & 39 KOhms corresponding to Pulse 1, Pulse 2, Pulse 3, Pulse 4, and Low speed settings. If you do not get values as stated above, then either the switch or the circuit between the switch & the motor is to blame. To narrow that down, testing at the multifunction switch connector under the steering column for the same values listed above would be required.

BTW, if you have your vehicle information in your signature, please make sure to attach it to your posts. The more people have to work to get your vehicle info, the less likely they are to respond.
