Does the XC90 use some sort of control module to operate the headlights & dash lights like the "C" word (Chebbie) trucks do? Fuses are good, Both Lights will go to hi beam when you pull the stick/switch back but drop back to low beam when you release it. messaging Display window & odometer window are at full dim. Can only be seen at night. No response to the dash dimmer thumb wheel. Daytime driving lights are in-op. Fog lights are in-op. REar fog light in-op. Rotary head light Switch position is meaningless. ECM issue or something else maybe? Anybody else been down this road? Thanks in advance
