POWER WINDOWS, WINDSHIELD WIPERS AND 4 WHEEL DRIVE STOPPED WORKINGTHR

2001 Ford F-150 • 136,000 miles

The power windows, windshield wipers and 4 wheel drive stopped working on my 2001 ord f150. I have checked the fuses and relays. They check fine. Could this problem be related to a weak battery? While the battery will start the truck, it seems very weak. The battery terminal are clean and good. Could low battery voltage contribute to this problem?

Weak batteries cause a lot of problems. Have it checked for condition including load test. There are a couple of fuses in battery junction box as well as a battery saver relay so that may be your problem.
