4 Auto?
2003 Explorer. Yesterday was going up a snow covered hill in 4 auto seemed like it tried to engage. Felt like it could not make up its mind if it wanted 2 or 4. Is this normal? Does it go in and out of 4 rapidly? Went back up the hill and this time put in 4 high and engaged good, same with 4 low.

ranger88a is correct. 4x4 auto only engages when it detects slippage at the rear wheels. I found out in my 97 Explorer when you had full snow coverage on ground and felt the 4x4 auto kicking in and out, I would just put into 4x4 high. I did this for better traction and also that why should I let the transfer case beat itself to death constantly switching the 4x4 on/off on/off....... I would assume that this would cause the transfer case to heat up. Use common sense. Engaging the 4x4 high is as easy as turning a switch (pre 2002) or pushing a button (post 2002).
