Flashing 4wd switch lights
Last year when it got cold my 05 Traillazer LS started having issues. When it got cold and snowy, the 4wd switch lights would all flash when the car was started and then go to the 2hi or whatever was selected and that light would flash then after 15-20 flashes all lights go out and have no ability to use the 4wd. The weather broke in 2 days and all was good until it got cold and snowy this month and it started again. I finally broke down and took to dealer. Was diagnosed as the actuator on the front axle.......replaced. this did not fix it. They replaced a spider gear in the front axle area that the actuator engages, and thought was fixed. But was inside the warm shop. They parked it outside overnight and you guessed it, same issue. Took it back inside and can't find what is problem. Said they checked the TCCM (?) but it was not that. I feel this is electrical issue as the trans/4wd works great in warm times......ANY IDEAS FOR ME TO RUN BY THE DEALER? They have had it for a week so far. I feel they are making honest effort but its a mystery...
