MillDoGG Posted June 27, 2005 Report Share Posted June 27, 2005 My friend, you know him as speedy. Just got his 98 sts returned to him from the shop. His N* was replaced from the same model and year. The car is running perfect, although the OBD-II code is given. The code P-1604 from what i researched is, "The loss of IPC (Inst Panel Cluster) serial data." His gauge cluster will not work ethier nor, his AC panel. he can control the AC, just no display. What could cause the gauge's to lose Power? They have checked fuses, and grounds, with no avail. Any Ideas Link to comment Share on other sites More sharing options...
