Chevrolet Repair: Chevrolet 1993 4 wheel drive, vacum, fuses

Question
My truck feels like it is in 4 wheel drive but the FRONT  wheels are not pulling.  I checked all of the fuses and they all seem to be ok.  Any ideas on why the front wheels are not pulling.

Answer
Hi Duke...check for vacum at the cable pot for the front axel.... if no vacum at the pot check the vacum solonid that supplies that pot to see if it is opening when you engauge the 4x4. if not check that you have power there when you engauge. if you have power change the solonoid.hope this helps
