PAUL T Posted September 20, 2004 Report Share Posted September 20, 2004 Have you checked the fuses? Link to comment Share on other sites More sharing options...
KHE Posted September 21, 2004 Report Share Posted September 21, 2004 PZ2471 is the interior lamp fault. Check the 10amp fuse (INST LPS) in the underhood fuse/relay center. If it is OK, then remove the interior lamp relay in the trunk fuse/relay center. Measure the voltage at the orange wire (A9). If you have battery voltage, then measure the voltage at terminal B7 (dark blue wire). If there is less than 1 volt, replace the relay. If you do not have battery voltage at the orange wire, look for an open or short to ground in the supply circuit (680 I believe). Post back your findings.
