It appears that the unit on the back of the wiper motor is out of sync with the motor movement It can be reset but generally unless you are capable of doing this best get a replacement wiper unit

SOURCE: windshield wipers on 03 silverado does not shot off,

Your wiper motor has shorted out and needs replacment.
In order to find out you need to disconnect the wiring from the wiper control switch,with the ignition on, if the wipers stop then you need to replace the switch.
If the wipers keep running, then you have a defective motor, replace the motor.

SOURCE: My wipers only work on high

The fault in this circuit board is quite common and is attributed to bad
solder joints from either design error or manufacturing flaw. Symptoms
which indicate a bad circuit board include (but are not limited to): wipers
will not work or work intermittently; wipers stop working for no apparent
reason, maybe even in mid-stroke; wiper function is erratic, with no delay
feature, delay is the same regardless of setting, or no low- or high-speed
setting; wipers may start to work if you tap on the wiper module or move the
electrical connector.

You have a choice of either Repairing your existing circuit board yourself,
or Replacing it.

Replacement - You have at least three options available to you, depending on
your relationship with your dealer and how much of a stink you want to put

1. Pay for the replacement part plus the labor to have the dealer install it
(~$50 for the part plus ? for labor. Most expensive, least work).
2. Pay for the replacement part and install it yourself (~$50 for the part,
your labor is free. Takes about 15 minutes.).
3. Have the part replaced under recall if applicable (Free, minus the time
your truck will be in the shop. Least expensive, most work.).
4. (Repair it yourself - Instructions below after Replacement)

Option #1 is very straightforward, just go down to your local dealer and
have him do the work and pay the bill when he is finished. You don't even
have to read any further.

Option #2 is also very straightforward. Have the parts department research
the correct part number for your model year circuit board, purchase the part
from them and install it. The wiper module is a small 2"x 4" black box
attatched somewhere near the top of the firewall on the driver's side. It
has the wiper motor mounted to it, and an electrical connector plugged into
the end. Remove the electrical connector first, and using a Torx (6-pointed
star) driver, remove the cover from the module. The circuit board sits
directly underneath the cover and will be coated with grease. Gently pry
the circuit board out of the module, do a little spring cleaning inside the
case and add a dab of grease to the drive gears if needed. Install the new
circuit board in the same manner as the old one was. Clean the inside of
the cover and reinstall with the same Torx head screws.

Option #3 gets a little involved. First you must find a recall notice for
your truck. Start by checking on the internet at and drill
down thru the links for recalls to determine if your truck is actually
listed (there are other sites to check as well). Just because your truck
may not be listed doesn't mean it's not under recall. It could easily
depend on how your truck is described. For example, a 1995 Chevrolet C1500
Pick-up could easily be listed as a C1500, 1500, 1500-3500, C-Series, C/K
Series, Chevrolet Truck, GM Truck, C10 (the old designation), etc. It would
pay to look under as many designations as you can think of before giving up.

If you find your truck as listed, so much the better. Print out a copy of
the recall and wave it at your dealer's service manager and they should fix
it No Questions Asked. If they still refuse, contact Chevrolet/GMC Customer
Assistance and/or the NHTSA's hotline (both are toll-free and listed on
their respective web sites).

If you do not find your truck specifically listed, all hope is not yet lost.
Search for the same truck under a different model year, or a substantially
similar vehicle which does have a recall (For example, the Chevy Blazer
shares the same wiper components as the Chevy S-10 and Astro, the GMC Jimmy,
Safari and Sonoma, the Olds Bravada, etc.). Print out a copy of the recall
for the other vehicle and go to your dealer's parts department. Have them
search for the part number of the circuit board for the recalled vehicle,
then for the part number for your truck. Odds are in your favor that they
will both be exactly the same. Hence, your wiper module is one of the
faulty ones being recalled and should be covered but your truck may have
been left off the recall list. Take this info to the service manager and
depending on how much he wants to keep you as a customer, he will find a way
to have the board replaced under the recall. If not, then you still have
options #1 and #2 above, or you could fix your existing board yourself.

Repair - You can easily repair your existing board if you know how to turn a
screwdriver and know which end of a soldering gun to hold. If you haven't
mastered either of these skills, then have someone else do the job for you.

Step 1 - Locate the wiper module and remove the circuit board as described
in Option #2 above. Be VERY careful removing the circuit board. Do not
crack, bend or break it or you're outta luck and will have to buy a new one.
The circuit board is approx. 2"x 4" and has two distinct sides. The top is
the side where all the components live, especially the large black socket
for the electrical connector (more on that later). The bottom is where all
the lead wires from the electrical components poke thru the board and are
soldered to the printed circuit. Carefully wipe the excess grease off the

Step 2 - The fault in the board is caused by bad solder joints holding the
large socket onto the printed circuit. If the board itself is cracked or
broken, then you will have to get a new one. Carefully inspect the tiny
mounds of solder underneath the large socket on the bottom of the board.
Each drop of solder connects a lead wire from the socket to the printed
circuit. A bad solder joint may look like it has a tiny circle in the drop
of solder around the wire end, a chip or crack in the little ***** of
solder, or it may be too small to see. At this point you will need a
soldering gun and solder, and a steady hand.

Step 3 - Set your circuit board bottom side up so you can see the solder
joints for the socket onto the printed circuit. Heat up your soldering gun
and apply just a tiny drop of solder to the tip. Place the hot tip with the
melted solder directly onto the existing solder joint in question just long
enough until the gun melts the existing solder and the new solder mixes in
with it. Remove the gun from the work and allow to cool. Remelting the
original solder and adding some extra should repair the joint and make
continuity again and reinforce it. Repeat for all the solder joints in
question, and/or all the solder joints for the socket. Don't overheat your
work, or solder may run down and create a short to another circuit, or you
may unknowingly fry a component on the other side of the board.

Step 4 - Allow everything to cool, then reinstall the board as listed in
Option #2 above.

Thnaks & Regards

SOURCE: 1983 chevy pick up wipers won't turn off

The wipers have a control module in the wiper motor. That is what is wrong. On that model you will have to replace the wiper motor . Good Luck

Looking for the fuse for the wiper motor 2008 chevy impala

WPR fuse 25amp under hood fuse box .
Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper PCB relay
• Wiper high PCB relay
• Windshield wiper motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR fuse 25 A
• WSW fuse 10 A
This is more then likely not a fuse issue !!!!!!!
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !

Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.

Wiper motor works intermittantly, and only on high.

If the wiper control module has been replaced and the problem is still present, suspect a wiper switch. There are numerous resistors incorporated into this switch to control the different functions of wiper operation. If one or more resistors fail, the voltage to the wiper module will incorrect and cause problems

My windshield wipers won't turn off on my 2004 silverado

CHEVYS ARE RENOWN FOR THEIR EXCELLENT WIPER SETUPS, The wiper switch control is more likely to be the suspect other than the wiper motor. New ones don't cost too much an not that hard to install. In the mean time, Find the fuse for the wipers and familiarurize yourself with it so you can remove it and still drive. Ensure the fuse does not operate any other important function before you remove it. Good luck

Wipers only work when switch is in high,but when i shut the switch off the wipers stop werever they are at the time.they do not work on intermitent or slow speed.

I had the same problem with my 93 Lumina and then it would work ramndomly then quit Wiper motor was the problem Changed all fuses first to no avail Wiper motor fuses are under the glove box behind the coweling as well as in the fuse box beside the glovebox for info
