Re: 97 silverado wont shift into 4 wheel drive
Check the 4x4 fuse to see if its blown. On the front axle on the passenger side is where the front axle actuator is located, just look for wires going to something screwed into the housing, it could be a metal or plastic actuator depending on whether it was updated. With the ignition on and a 4 wheel mode selected there should be power to the light blue wire(and brown wire will have power if you have the update). If the wires have power replace the actuator.
If you have the metal thermal actuator its easiest to just get another, to do the upgrade you need a wiring harness adapter and a spacer that goes into the axle |

Re: 97 silverado wont shift into 4 wheel drive
With the switch lights flashing as you described I would suspect the encoder motor on the t-case.

Re: 97 silverado wont shift into 4 wheel drive
hi
thanks for the replies. i have tried a few things and have something to add. with transmission in neutral and engine running - when i switch from 4-wheel high to 4-low there is a definite engagement in the axle. same sort of noise when back to 4-high. is this noise the actuator working. there are 2 electrical connectors attached to transaxle - when these are disconnected it still makes clunking noise when switchin between 4-high and 4-low. not sure if this photo i added is the encoder - it is threaded into side of transfer case and has a rubber sort of skirt on it. thanks again for any help. mike |

the problem you have is either the encoder motor 90% or the transfercase... your problem is no 4X4 drive correct ? the encoder motor is binding or unable to move because of its lack of power to move..could be poor connections external and other possiblities..but not usually.. what is the fluid in it ? when/how often do you replace your transfercase fluid ,and what fluid do you use ? |

Re: 97 silverado wont shift into 4 wheel drive
the noise your hearing could be the transfer case engaging remove the avtuator from you front axle and let it hang their with your key on and i n withyour 4x4 on the actuator should come out if it dosent replace it this a very common problem for these

they no longer make dexron III...so you should check with the dealer with your vin to be sure of the correct fluid to use... I believe it to be now on your 1997 tracII fluid...but check that with the dealer..the encoder is most likely binding or defective..some have found these parts for less than 200.00.. |
