Wipers quit working in intermittent mode, they would not start up in slow or fast mode. We parked for a time, maybe ten to fifteen minutes, with the wiper control off. They started when we turned them back on. We drove for about fifteen minutes and they stopped again. We narrowly escaped the highway and parked, turned off the wiper control. We waited about fifteen minutes and they started again. We were then able to drive three hours to our destination without a problem. The following day, raining still, we drove around town without a problem. However, later that evening in heavy rain and on a crowded Southern California freeway they stopped again. We parked and waited and they started again. We continued towards our destination but they stopped again and we had to drive with our hazard lights flashing because there was no way to pull off. This time they started back up while we were driving. We have not had to use them since.
Just before our first episode we had hit a deep pot hole that jolted us pretty good. Otherwise there is nothing else out of the ordinary.
We are scheduled to drive from Southern California to Portland, Oregon later this week and are concerned we will have problems. I called the local Toyota dealer but they said if the wipers are working they could not determine what the problem is.
