Question about 2003 Chevrolet Silverado 1500
Can not get the windshield wipers to turn off. they will turn on high speed when the switch is changed, but will not quit working when in the off position.
I also can not locate the specific fuse that will pull the power
Fixed the wiper problem which was identical to Brad's by changing out the wiper module which is also called a pulse module or something of that nature. Pretty easy fix. You have to remove the grill that the wiper blades protrudes from in order to get to the motor (4 clips in front which can be removed by hand, remove radio antenna, a center push down retainer, two plastic end caps which pop off and then 1 star type screw on each end under the end caps). Getting the blades off seemed difficult. I used a small puller to pop them off after removing the nuts.
You can't buy this module at a regular parts store. I had to get it from the dealer so be prepared to spend $130 to $140 for the part or go to the salvage yard. Works great now.

I had the exact same problem where my wipers would not turn off or run intermittently on my 2003 Chevy Silverado without having to pull the fuse for the wipers (that is scary when you have to open the drivers side door on a busy freeway to pull the fuse to turn off the wipers! YIPES!). I had a mechanic to replace the module located just above the wiper motor behind the three screws and it successfully resolved the problem. I first tried swapping out the switch on the steering column with no positive results; wipers still would not turn off.

Does anyone know where I can get a wiper pulse module and have a part number? I have a 2004 Silverado experiencing the same problem.

On the wiper motor under the hood is a control module. remove the three screws and replace the part. You can get the part at most parts stores.

This is possible for anyone even remotely mechanically inclined and worth the effort. The part alone at a Chevy dealer is $161 plus the labor to install...expect $250 to $300 versus about a $70 fix at home.
This takes 60-90 minutes from start time. Tools required are small torx screwdriver, wiper removal tool, 13 mm socket, couple of small flat head screwdrivers, small wire brush and Large Channel Locks.
Step 1. Disconnect battery ground cable.
Step 2. With grease pencil, mark alignment of windshield wipers on windshield and then disconnect washer hoses to windshield wipers.
Step 3. Pop off bolt caps on windshield wipers and take off bolts.
Step 4. Potential problem...utilizing a windshield wiper removal tool (purchase one at Advance Auto for $13.21 including tax), remove windshield wipers. I tried a gear pull, but couldn't seat it properly below the blades. Do not try to rock them back and forth or pry them off with a screwdriver. It is easy to damage the groove on the blades and mounts. After removing clean wiper mounts with small steel brush.
Step 5. Unscrew torx screws on each end of wiper grill and remove four tabs at bottom of grill. Also, there is a plastic inserted screw that pops in and out in the middle of the grill that needs to be unseated. Use a flat head screwdriver to do that.
Step 6. Remove antenna
Step 7. Slide grill up out of the way to reach wiper motor.
Step 8. Remove four bolts of what looks like a protective piece of metal over the wiper motor housing for easier access to the pulse control board.
Step 9. Remove the three screws with small torx screwdriver holding pulse control board in place and carefully disconnect six prong connector.
Step 10. Attach new pulse control board. ($59.99 special order at Autozone, 1 day to arrive). This is a bit tricky. It takes quite a bit of force to get those darn prongs seated into the connector. I actually used some large Channel Locks to squeeze them together. Once they initially start inserting, it slides right on, but it is tough to get it started.
Step 11: Reinstall using the three torx screws into the wiper motor.
Step 13 - 21...reverse the order and put everything back together. e careful with the two sheet metal screws that hold the wiper grill in place. The end of the wiper grill is fragile and you can break the screw holes.

I have a 2003 that has the wipers only running in high speed and won't shut off. I can relate with the guy who talked about the danger of removing the fuse in high traffic conditions.
The Chevy Dealer in Brookings, Oregon wants $175 for the control module. Is there a cheaper way to replace it?
