: the contact stated while the four wheel drive was shifted from four wheel drive high or low, the vehicle will not always shift. The four wheel drive light illuminated and the audible alarm stating the vehicle has not shifted came on. An additional 5 attempts were needed after the vehicle was moved. The technical representative from the manufacturer drove the vehicle and determined this was normal operating conditions. Also, when the outside temperatures were below zero degrees the keyless entry would not unlock the vehicle. The dealership tested the key fob and replaced the battery, but this did not repair the problem. Updated 3/22/2006 -.
While performing a normal review under the hood, I discovered the oem delphi battery had sprayed acid on the under side of the hood which ran down the fender well (removing the paint on both) and continued running down to the frame and ac line.
