Wipers keep getting stuck in up position!

When I turn on my wipers they are very prone to getting stuck in the up position. This has been happening more and more lately.

I press down on them and they go back down and come back up and stay up!

Sometimes they operate fine, but it is becoming rare...

Suggestions?

See this thread (http://www.automotiveforums.com/vbulletin/showthread.php?t=337899&highlight=wiper) and in particular, my last post. My guess is your latch isn't catching.
