Do everything possible to solve the abnormal noise

● Do everything possible to solve the abnormal noise

The abnormal noise of my wiper has lasted all summer. At the beginning, I also thought of some ways to find the cause of the abnormal noise, such as checking whether there are foreign objects on the wiper blade, whether the wiper blade is uneven, and whether there is grease residue on the glass. Even I replaced a brand new wiper, which didn't solve the problem.

In desperation, I had to go to the 4S shop to find out the reason, but the staff in the shop did not tell me what was the cause of the abnormal noise, but told me that the wiper arm needs to be replaced. The cost of the work and materials was several hundred yuan , I felt "meat hurt" when I heard the news. I feel that it is not worthwhile to spend a few hundred dollars on a small thing like a wiper. I still think of a more cost-effective way.

● Find out the cause

After a series of investigations, the abnormal noise of the wiper was still not resolved. Finally, through careful observation and disassembly of the wiper, I finally found that the problem that caused the wiper to jump and the abnormal noise was that the wiper arm was crooked, which caused the wiper strip and the windshield to not be very strong. Good fit.

● Start repair

The reason has been found out. The next step is to adjust the wiper arm. At this time, we need to prepare some small tools. First, we must prepare two adjustable wrenches. Of course, we can also use pliers instead. Then we must prepare a flat-head screwdriver. A towel.
Through actual operation, I also want to remind you that you need to pay attention to several issues before doing this: First, determine whether the cause of the wiper jump is because the arm is crooked, because there are many reasons for the wiper jump, such as the wiper strip There is damage, the windshield is greased or rain-proof products are applied, etc., my wiper problem is only one of them; secondly, the direction of the wrench rotation must be distinguished during operation. The top, if it jumps down, you need to turn the top of the boom clockwise; finally, don’t use too much force each time you twist, a little bit of fine-tuning, too much force will easily damage the boom, you can install the wiper after each adjustment Try the bar until it doesn't jump.
