The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
The wiring to the washer system heater may overheat due to a failure in the heater module.

At customers' request, a dealer can install the label for them. The recall began March 31, 2006. The GM recall number is 05109.
