i have a 2001 Rager, 4WD, 6cyl, 4 liter. I got in my truck this morning to go home from work. Here in Memphis, we are having a snow storm. The temp was about 12F. However, I have driven my truck much colder and worse ice/snow. Anyway - my 4WD switch was set at 2WD as it has been for 2 days. I used 4HI to get home 2days ago but have been 124mi since. This morning, I started the truck and began clearing the glass. When I jumped in and got ready to head home - the switch was in 2WD. However, the 4WD HI AND the 4WD LO lights were illuminated. I used the switch to go to 4HI and 4LO then moved enough to make sure the front diff was not engaged. I also used the owners manual to make sure the diff was unlocked before heading home. After the thermostat opened and engine was up to operating temperature - both lights went out. This truck and I are accustomed to ice, snow, heavy farm mud, rain, etc. Anybody have any ideas? Thank you.
