Boy just bought a 98 Blazer 4X4. Appears to be a nice ride but am having a little problem with the auto 4X4. This truck is a 6 cyl, auto tranny and can't seem to get it in 4X4 high. Can get it in 4X4 low but when we do it is a real pain in the arsh to get it back into 2 HI. I am thinking it is an acuator but would like a little help on where to start looking. Thanks. and oh ya there is a Amigo in the truck section for sale if anyone is looking.
