4 Wheel Drive/SUVs: 1995 silverado

Question
thanks for being here......do not know if its connected but started out air would work sometimes mostly in the mornings, when you really need it it quits,it started out being once in a while the fan would not work could wait a while and it would turn on or sometimes turn engine off wait few minites and it would come back on... heater fan will not work, if it does come on after cranking only for few seconds, when fan does not work it also will not go into 4 wheel drive, started out doing this occasionally now  just will not work

Answer
Ron,

If it was just one of these problems, it would be much easier to trouble shoot.  It sounds like you have a major ground problem.  I would take it to a reputable shop, and have them run a diagnostic on the vehicle.

Like I said, it really sounds like a bad ground.  If that's the case, it should be a simple fix.
