So we got hit by several inches of snow Friday night that proceeded to melt all day Saturday only to refreeze to black ice saturday night, so naturally I stayed the F home, today I decided to pull the truck out of the driveway so the rest of the driveway could melt (truck was blocking the sun from hitting it) naturally this took 4WD, so I flip it into 4HI and BOTH 4HI and 4LO are illuminated on the switch, pulling up the driveway feels like 4HI but then as I begin looping the culdesac it feels like 4LO, I shut off and restart the truck and am able to get back to what feels like 2HI, but now I have a Check 4WD light on the IP and ALL the lights on the 4x4 selector are off (they all cycle on and off when cranking), flipping the selector switch around does nothing (including the holding in Neutral position for 10 seconds), truck is an 03 trailblazer with 220k ish miles, transfer case fluid changed when transmission was replaced last year (about this time of year) so about 5-10k miles since last serviced, can't find a fuse for the TCCM like described in other threads here. Advice on where to start?
