Chevrolet K1500 Suburban Wiper Pulse Module

Spotting a Bad Chevrolet K1500 Suburban Wiper Pulse Module

The Chevrolet K1500 Suburban wiper pulse module is known for being a faulty device on your truck. The problem is so common that it isn't limited to the Suburban. Other models under GM are affected by the part as well. Wipers erratically behaving are one of the earliest sign that your truck may already have a bad module. It's as if the wipers have a mind of their own. However, before you go out and buy a new one for your truck, it is important that you discount other areas that may cause the problem. Here are some of the areas you should look at to be certain that you have a bad Chevrolet K1500 Suburban wiper pulse module.

Burned fuse

Checking the wiper's fuse located at the fuse box is a good place to start. It isn't as difficult to access and replace compared to the bigger Chevrolet K1500 Suburban wiper pulse module. The fuse has a tendency to burn out after prolonged use. The conductive metal strip may be worn and in need of replacement. This can happen earlier if you fail to regularly maintain the ones on your truck.

Disconnected wiring

There are many wires that are connected from your Chevrolet K1500 Suburban wiper pulse module to the power source. One of those wires should be connected to the main power line. The others power a certain pulse setting for the wipers. If any of these are loose or disconnected, then it doesn't come as a surprise that your wipers are move inconsistently.

Adjusted voltage and resistance

It is also possible that the electricity running through your Chevrolet K1500 Suburban wiper pulse module is not as strong as it should be. The resistance level may also be too much be too much-it should be less than 5ohm. Use a reliable voltmeter to see if the electrical flow is as strong as it should be.

Damaged circuit board

If all looks well and your wipers still act funny, you can be certain that you have a bad Chevrolet K1500 Suburban wiper pulse module. When you check the insides of the module, you should see the circuit board-the mind of the wipers-that is responsible for controlling its speed and pulse. If the joints, sockets, and other areas are cracked, broken, and loose, go ahead and get yourself a new Chevrolet K1500 Suburban wiper pulse module.

  • Tips to Delay a Chevrolet K1500 Suburban Wiper Pulse Module Failure 04 March 2014

    The wiper pulse module on old Chevy models has a bad reputation for being very weak and quick to failure. A problematic module is known to cause your truck's wiper to wildly behave. The easiest and most convenient way to fix the problem is by replacing it with a working unit. If you think that it takes some time before you get the part you ordered, there are a couple of things you can do to delay a Chevrolet K1500 Suburban wiper pulse module failure. You need to remove the part from the car for you to service it. All it takes is a little patience and basic DIY skills to get the job done.

    • Constantly check the wiper wiring.
    • Electrical problems don't necessarily mean something's wrong with the electrical device itself. In the case of the wiper pulse module, a problem with the speed of the wiper can be caused by faulty wires. Check with a voltmeter to see if electricity runs properly. All wires and grounds should be connected as well. All these could become loose as you drive your truck.
    • Clean the circuit board.
    • With a few simple tools, you can open the insides of your Chevrolet K1500 Suburban wiper pulse module. Inside is a small circuit board that regulates the speed of your wipers. Dust and dirt can land on the board and block the connections between the wires. Dried grease can also cause clogs. Clean these off so that contact is always clear.
    • Solder the parts to the circuit board.
    • The common cause to erratic wiper pulse modules is a loose connection between joints and sockets. If the chips and cracks are too big to be soldered, you're better off not using the part and just wait for the new unit to come.
    • Retouch the connecting wires with dielectric grease.
    • Other than soldering, you can apply some dielectric grease to enhance the connections on the circuit board of your car's wiper pulse module. The amount of grease decreases as you continuously use your truck's wipers. Check the module once in a while and replenish the grease if necessary.
