Help fix windshield wiper problem!!!!!
Only the fastest speed setting works for my wipers, they don't move when I put them on intermittent or slower speeds AND I cant get any wiper fluid to come out(they dont even move when I try to use it). I had the exact same problem on my silverado, so maybe its a GM related problem.
Any help would be appreciated, thanks guys!

Not much to it. You'll need a meter for voltage/ground checks.

In a nutshell...yes. That way you can check for the appropriate voltage based on the switch selection. If it's all good, then the motor is suspect..if it's not good, then you have to dig deeper into the column switch.

With the ignition on(and wiper switch set to off) you should have the following at the motor plug:
Pin A - Ground
Pin B - Battery voltage
Pin C - 0 volts
Pin D - 0 volts
Pin E - 0 volts
what should i do next?

Thats easy! You need to CYCLE the wiper stalk thru the differnt positions and record the values noted on the meter for each pin number. One will be a continious variable resistance, one will be a stepped resistance B will/should always be 12 VDC A should always be ground.

I had a problem similar to this with my wipers starting and stopping as they pleased. I ended up changing the wiper selector out for a new one. Not a bad job, but you need to take apart the dash and column.
This is a GM problem. The wiper selector stalk that is in most all of their vehicles is a ticking time bomb as I suspect it was designed by the lowest bidder on drugs.

hopefully these numbers help someone find out what my problem is since i am a complete caveman when it comes to voltages, circuits and ohms and that kind of stuff. Thanks guys.

Those numbers dont make any sense. They change very little in all the positions.If your changing the position of the stalk and changing the duration of the delay, the readings should be changing also. Disconnect the switch from the circuit and read the pins using an OHM Meter and see if the resistance changes with the movement of the stalk.

i'm also having wiper problems (mine won't go off... $%&@!!) Ordered a new wiper motor today for bout $60 bucks... like you, i don't know squat about electrics. hoping the motor resolves my issue. otherwise, i'll be back here to follow the troubleshooting mentioned above.

Check out this thread, it has a link on accessing the stalk to remove it. and shows repair procedures you might want to try. If not contact Gene at GM Parts House to buy a new one and do the replacement swap yourself. This is about $800.00 bucks at a GM Dealer !

took my wiper switch apart today, cleaned the internals and dielectric greased it..does the SAME thing. I think i'll be taking the wiper motor apart tomorrow and messing with that next.

OFF:
A-0 Correct, A is ground.
B-11.67 Correct when in ACC or On.
C-0 Correct.
D-0 Correct.
E-0 Correct.
INT:
A-0 Correct, A is ground.
B-11.66 Correct when in ACC or On.
C-0 Correct.
D-11.38 Correct
E-6.92 Incorrect, if you are measuring at the motor connector with the connector disconnected from the motor as you state in your post then this pin should read battery voltage in all positions except off. If connected to the motor I can't give that without knowing the rest of the circuit in the motor. However, I would expect it to be a voltage say 2 volts increasing until you select lo where it will become battery voltage. It would also be battery voltage in mist or high as well. 0 in off.
LOW:
A-0 Correct, A is ground.
B-11.65 Correct when in ACC or On.
C-0 Correct.
D-11.38 Correct should be battery voltage in all positions except off. Again assuming the connector is unplugged from the motor. If connected to the motor I'd expect it to be similiar to or higher then pin E when on the highest intermittent setting.

Hello Vette lovers. I'm new to this forum.
I've similar problem as above. I have non stopping wiper that could be related to clogged udders (is there a link where one can unclog this as I have no idea where it is) or wiper control stoke (stalk?? ).
As this was happening, when I pressed the washer fluid button, damn button just flew out. WTF?? So, am I looking at replacing the whole stalk or can some parts of it be replaced?
Thanks in advance!
