94 Chevy K1500 4wd wont engage

[steveninspokane]

Help...

i recently replaced the pasenger side front axle on my 94 Chevy K1500, and now the 4wd wont engage... when replaceing it in the housing, there was a washer i wasnt sure if it was in the right place, but now after all that and putting it back together, the 4wd wont engage, the light wont come one, and you cant feel any difference when trying to put it in to 4hi or 4 lo... i checked the 4x4 fuse, and its not blown, none of the other fuses seemd to be blown, so im not sure what to do, id liked to get this fixed soon, and without having to take it to the shop... any help would be great, millige is about 260,000.

Didi you have to unplug any wires ? Check for wires or vacum lines not hooked up

There should be a set of wires/plugs under the truck near the center of your yoke. Make sure they are connected. They connect to a silinoid, that when you put your truck in 4wd the silinoid will engage the pins that lock your front axles in. Your truck may have to move foward or back to engage.( Most chevys have that problem over time.) If the wires are connected and still don't work your silinod might be bad. Hope this helps.

Hey I have a similar problem with my 1988 k1500 4x4. I get no light indicating that the 4x4 is engaged. To keep it short and simple if that light does not come on, the actuator is not working. I have to go get a new actuator for mine also. Working with some other more serious leaks (transmission) on my plymouth voyager. Also, I've fixed a couple of other electrical issues with my truck (wipers, fuel relay, computer grounds). All of my problems were in the ground. Devices weren't getting a good ground.
