Replaced front wiper motor due to grinding noise, but wipers worked fine. After repair turned on wipers and they stick on all speeds and high is very slow. They work normal when glass is wet, but as it dries they slow down and then stick. Can you help?

Wipers should never be used on dry glass because the drag can easily overheat the motor and damage it. Unless I'm missing something, what you're describing is normal. As long as the speed is normal when the glass is wet, I doubt you have a problem.

This is not normal because wipers worked just fine before replacing motor due to noise. I went to another auto parts store and got another motor and wipers work fine and no noise. This site is not very helpful.

Thankfully 99 percent of the visitors to this site disagree with you, so you are in the minority. The fact is every mechanic is trained to not run wipers in the shop on dry glass. The fact you aren't informed of that is no reflection on the value of this site and the help we provide.

Your original replacement wiper motor had nothing wrong with it. You proved that to yourself when you observed it worked properly when the glass was wet. It did what it was supposed to do.
