Question about 1997 Chevrolet Suburban
Anchorage, AK. Conditions-snow and icy roads. 1997 Suburban. Night before pulled in driveway in 4 Hi and next morning Light is flashing on the 4 Hi selector. Lost 4x4 function. Thought it was thermal actuator (plunger) switch, so replace with same. ($124.00) (heat activated) Light still flashes, and still no 4 x4 Hi or Low. This all came about after backing out of driveway. No sudden change or event before this happened. Usually leave 4 Hi engaged for most of winter, except if driving on highway and it is in good condition. What it next step???
I do hear the actuator engaging.
It sounds like the spring loaded pin that the plunger activates is stuck or broken. If its not to cold tap on the housing and see if it kicks in. If not consult the book for an exploded view. If your manual does not have the view go to the nearest dealers parts department and ask them to print you one.

SOURCE: 4 Hi light flashing
Try this before you do any repairs or sp[end any other money. Make sure that vehicle is on a flat surface. Start vehicle and Push down on brakes while holding brake put vehicle in neutral. Still holding brakes in NEUTRAL, Engage 4x4, it should work. If it doesn't get back to me. Good Luck. If I fixed ya leave me a FIX YA comment
