Question about 1999 Chevrolet S-10 Pickup
I have seen several instances of this. The transmission fluid is migrating from the rear of the transmission through the seal on front of transfer case. The transfer case is eventually overfilled and then flows into the vacuum lines. Before you clear the lines, remove the vacuum line from the module under the battery tray. Compressed air will destroy the bellows.You can remove the top fill plug on rear of transfer case and drain out excess oil. You would have to do this about every engine oil change. The alternative is to remove the transfer case and replace the bi-directional front seal and adapter gasket. When the transfer case is overfull, oil will come out the vent tube near the transmission dipstick. But this is too late as oil is already in the vacuum circuit, and may also plug the vacuum switch on the transfer case. Eventually the rubber on the module, under the battery tray, will be damaged by the oil.

Encoder motor, but make sure when your button is pushed or switched to 4 hi that it either blinks or shows some kinda light, this is a poor mans way to make certain that the electrical portion is trying it's part but the encoder internal reistat is not giving the correct position to the response
