Truck Repair: 93 S10 Blazer 4x4 4.3L auto..., dry pavement, s10 blazer

Question
Hello,

Just wondered if it was ok to leave it in 4 wheel drive high/low? It's been very cold here and wondered if temps played a part in this sort of thing, similar too e-brakes freezing up when used during cold times. Can you explain to me what it does/doesn't do by leaving it in 4 wheel as opposed to disengaging the 4 wheel everytime you reach your destination?

Thanks,
Mike

Answer
Best to NOT use it in four wheel drive on clear dry pavement.
Temps play a small part in the vehicles with the thermal actuator, which yours probably has.
