This is kind of same subject as my previous thread about speedo not working. But. Different. Hope it is alright to start a new thread. I did a search. Could not find any thing pertaining to my specific problem. I replaced the motor on the speedo as all others were working fine. I reinstalled the cluster but left the cover off. I set the needles to correct position with ignition off. I can turn on ignition and turn it off and back on again and off. Needles return to correct resting position. If I start car up then turn it off needles go way past static setting. Losing calibration. I have gone though the procedure countless times with same results. Speedo is working again though. Help. Thanks.
