The common issue with this unit is a failed odometer and tripmeter. These units rarely suffer from other issues. If you have a bouncing speedometer, it is best to replace the cable. The base repair of this unit will not remove the lens or front bezel, therefore we will not clean the inside of the glass. If you wish to have the glass cleaned on both sides please select level 2 during checkout. (Please be aware, if the rubber back cover rubs off on your fingers, it will make the inner glass cloudy during shipping. We are not responsible if you do not choose Level 2). We strongly recommend having the glass cleaned by selecting Level 2. If you are experiencing any other issues/symptoms with this part, please call us before purchasing this repair 770-831-8802.
