went to have my truck scanned at the local auto zone and he gave me codes p0606 and p060b and then tried to clear but it said pass but it came back. they came with low windshield fluid warning, I pulled the fuse for the wiper heater before the scan under the hood. the pump for wipers still works with the wipers them self, any ideas. the wipers still come on with the sprayer once in a while by themselves and no i didn't touch it by accident. please help

 

anyone?
