Does anyone else suffer from the gutless heater syndrom?? My '86 Blazer is gut less on the heat out put...."High" is like what medium or low should be...i was wondering if this is just a thing that everyone has to deal with or could it be fixed??...Just got to thinking, that when it snows all day in the parking lot while I'm snowboarding, and come back and have to wait an hour to let it warm up enough to melt any snow/ice...not something I really want to do on a regular basis.... Also, is it OK to leave the hubs locked in and drive on dry/slightly wet pavement with out the t-case in 4? And when it does get slick then just throw it in 4wd without having to get out and lock & un-lock ?????
