GMC Sonoma (1999) 4-wheel drive problem

Can anyone give me a brief synopsis of how the 4-wheel drive works in a
1999 GMC Sonoma? Are the front axles engaged all the time? Are there
hubs to be locked, or automatic? Is there something (solenoid) that
engages the front differential to the axles? Is this operated by electric
or vacuum? Thanks

there is a vacuum pot with a cable to the front axle located under the
battery. when you put it in 4 wheel drive, a solenoid and vacuum switch on
the transfer case engage the front driveshaft and then the vacuum pot under
the battery engages the front axle. there is also a solenoid--on or near
the firewall, that supplies vacuum to this pot when the dash buttons are
pressed. If you have the automatic 4x4, and its not working, the plug on
the controller is probably rotted out... check for it under the right
front kick panel inside the cab.

Deep fry in peanut oil till crispy golden brown, drain on paper towels.



Lemon Neonate

Turkey serves just as well, and in fact even looks a bit like a
well-dressed baby. By the time you turn the child?s breast into
cutlets, it will be indistinguishable. The taste of young human,
although similar to turkey (and chicken) often can be wildly
different depending upon what he or she has consumed during its
10 to 14 months of life...

4 well chosen cutlets (from the breasts of 2 healthy neonates)
2 large lemons (fresh lemons always, if possible)
Olive oil
Green onions
Salt
pepper
cornstarch
neonate stock (chicken, or turkey stock is fine)
garlic
parsley
fresh cracked black pepper

Season and sauté the cutlets in olive oil till golden brown, remove.
Add the garlic and onions and cook down a bit.
Add some lemon juice and some zest, then
