Customer Question

We have a 2007 Cadillac Escalade equipped with the rain sensor wiper system. The wipers work fine on high and low but not intermittently or rain sensor. What should we test or change?

The most common cause on this is an issue with the Rainsense sensor itself. If the windshield has ever been replaced, there is a lens that was supposed to have been replaced at the same time. I'd start by looking to see if it's a replacement windshield.

If that's not an issue, then the sensor itself is usually the culprit. It's very sensitive, and attached to the glass with a conductive gel that allows the sensor to work. You can sometimes push against this sensor and get it to work, which indicates that the gel has failed and is obstructing the sensor's view of the glass.
