2007 GMC Yukon Denali Question: park assist warning comes on and car doesn't beep when close to something



Visitor, Atlanta, IN, May 24, 2011, 11:28

How can we check this problem or even fix it without taking it to dealership. The warning stays on all the time.

    Hi, if you have the knowledge of the repair car. I know some DIY GM diagnostic tools, maybe they can help you. It is not that difficult.

    you may want to clean your radar points on rear bumper and make sure there are no trim pieces or a hitch in the radar view - that will disable the park assist.

    I am a widow, this was my late husbands car/ truck. I cannot afford to pay for repair. Been driving 2 1/2 years without the parking assist working. Where would I look to find the "radar points" , and would normal car washing clean these areas. Or how do I clean them, if other than normal soap and water. Hope to hear from you soon.
