Hi, I`ve been having a problem with my 4wheel drive and, before I start
parts changing, I figured I`d ask. What`s happening is that my Jimmy is
dropping out of 4 wheel into 2 wheel. It`s intermittent, happens more often
when its colder outside, dash "service 4 wheel" comes on, and I lose 4
wheel. Happens in both Auto and 4High. Can be reset sometimes by restarting
the vehicle, other times not. A borrowed scan tool shows no hard codes but I
havent been in a situation to hook it up when its happening.
I`ve heard that the dash switch is problematic in this model with the Auto 4
wheel but was under the impression it was a complete failure problem not an
intermittent one. Ive done a good visual on the undercarriage,wiring to the
T/case looks good.
Any thoughts on how to proceed from here?
