With the viscous heater relay pulled I can read a code with the GDE tool but I don't recall if it's B10B3 VISCOUS/CABIN HEATER RELAY CONTROL OPEN CIRCUIT or P1102 which is a generic viscous heater trouble code. Doesn't really matter as it's definitely a viscous heater code and the code if cleared stays cleared if I plug the relay back in.

Opening up relay and removing contact arm should fix that!
