[6T9GTO]

I took the GTO out for a spin this weekend and ran through a rain shower. I haven't used the wipers for an extended period of time for many years. The wipers wiped about 5 times, the would only come up about 3 inches then go back down. I cut the switch off, and they continued to do the 3 inch dance for about 5 cycles, then finally cut off. I tried both the low and high speeds on the switch with the same results. Any ideas as to what could be causing this? I tried to pull the wipers up while they were in this "short cycle", but this didn't work. Any help would be greatly appreciated.

Thanks, Bill
