Thanks for the info. Its an ESOF/auto. The a/c heat vent is working ok. Do I have to do anything special if I need to run 4x4 low. (if I slide off road in ditch and need to get out?). Thanks again.
New here as well. First 4x4 truck and first diesel. Are you ready for some dumb questions? <that was the first one. the second is how do i know if my 4x4 is working? The third is my 4x4 locks on front wheels-do I have to lock them in even in 4x4 high, 4x4 low? If someone can just explain to me...
