Three problems related to wiper have been reported for the 1999 Ford Ranger. The most recently reported issues are listed below.
99 Ford Ranger XLT sport package. 5 speed manual. Truck body is rust free but frame has rotted out. Rust began on left rear frame and spread to entire frame and cross members. Spare tire fell off, frame cracked in half causing bumper to fall off, gas tank fell off truck hitting a small road bump at 60mph. Both sides of rear frame, bumper, and gas tank were repaired. Now frame has cracked in half under passenger side door. Truck is unsafe to drive with only 99,000 miles. Windshield wipers also go off intermittently and do not always work when turned on.
99 Ford Ranger, windshield wipers turn on by themselves while driving. Now wont turn on at all. Seems to be a driving hazard if your driving in the rain and they quit!!.
(1) the windshield wipers will turn on by themselves while I am driving the vehicle when I have not activated them. I may be traveling at 20 to 65 mph, sitting at a stop light, or turning at an intersection or corner, and the wipers just come on by themselves. (2) this event has occurred 2 - 3 times per week since 2007 and the consequence is that both wipers scrape across a dry windshield leaving tracks on the windshield. As I only have approximately 100,000 miles on the vehicle, these incidents began when I only had approximately 75,000 to 80,000 miles on it. (3) to stop the wipers, I pull over to the side of the road, turn off the engine and than restart the vehicle--this does not always work. The other is to put the wipers on fast speed for a couple of seconds and turn the wipers off. And this "solution" does not always work. At times during rain, when I first turn the wipers on, they will not turn on at all. I turn the wiper knob off and than put on high speed than back the speed down to get them working. A professional repair has not been made up to this date as I would like to know if this is a manufacturer's defect.
