Three necessary automotive multi-meters when wiper does not work

In summer, it rains often, if the car windshield wiper not work, move slowly or any other malfunction, then it will be an ignoring and dangerous thing when driving in the rainy day.

To determine what is causing your windshield wipers to malfunction and not work, the experienced car repairman know it is very important to investigate the wiper motor and switch to determine if either is causing the problem.
Take a 1999 Buick Century as an example. The first thing to check is the fuse for the wipers, in the fuse box. You can pull out the fuse and check it four ways. 1. Try replacing it with a new fuse (of the same amperage) 2. Look at it for internal breakage or discoloration. 3. Use a tester light thingie (clip on one end of a wire, and a pointy poker at the other end) connected to both ends of the fuse. If it glows, it’s good. 4. Test it with an automotive multi-meter connected to both ends of the furse. (Set to test Ohms/resistance) If the needle goes up near 0, it’s good.

As known, every experienced auto technician has one multi-meter in the repair box, and you?
