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.
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.
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.
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.
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.
