Hey guys, I got two questions/problems that maybe someone can help me with. 1) With my pushbutton 4WD I cannot select low range. I go into 4 high wait for the light to stop flashing and then select 4 low. The 4 low light doesn't stop flashing and then the truck just stays in 4 high. I have tried with the truck in park and nuetral and with the parking brake on and off. I have tried to let the truck roll a little thinking that would do it. Nothing works. Doesn't even feel like the t-case is trying to shift. 2) In NY, all winter the truck has stayed at 185 degrees. For the past two days when I lay into the truck I can get the engine temp up to about 200 just getting on the highway accelerating to 70 mph. It does come right back down but I have never noticed this before. Ambient temp is up to 40 degrees from 20 degrees. Normal or not?

On the temp issue, you may have a stuck thermostat.

On the 4-low issue, check the actuator to ensure that it is working and receiving voltage.
