My 4lo stopped working only 4x4 mode works my defrost is stuck on Idk anyone know how to fix this crap

 

check your vacuum where it goes into the cab, its passenger side of fire wall above the back of the engine

 

Oh man well I fix it and what a story so I check the engine today and couldn't find anything turned it on and heard a hissing sound check it and found that a small about 1 inch hose the bridges to lines together was totally spilit and half was hanging so I went to oriely got a free gap of hose put it in and holy $&@$ every thing works again.

 

glad you got it!

 

Yeah thanks for the advice
