1994 Chevrolet K1500 Questions & Answers
Radio problems
if it's the original radio, the part in the dash is not the radio, it is just the control head. the guts of the radio unit are under the dash above the accelerator pedal. did you replace all of it? or just the control head or just the actual radio under the dash?
My 1994 Chevy 1500 4x4 wont go into four wheel drive.
Sounds like the problem that I had with my '94 chev sub k1500, twice!
The first time it was due to a blown fuse. Now I carry a spare 20A fuse when I go off-road.
The second time the electrically controlled/heated, fluid filled actuator mounted on the front diff failed. I now carry a spare actuator when I go off-road.
the actuator is powered when the switch on the top of the transmission is energized. I have had no problems with that switch, or the connecting wiring.
So i got a 1994 chevy pickup z71 short bed single
K1500 , why skip telling this fact. K2500, k3500 ? we can't just guess.
we can not just drive the this truck and know.
impossible. post all driving evidence first.are you on ICE ?
no road conditions told
nor what transfer case option it has.
to fix 4wd, one must know the drive train.
if not there can be no good help.blind
transfer case full Dexron (max#) ATF fluid>?
not all leaked or leaking out.
NP205?? part time or NP208 part time,, not for pavement lacking ICE
NP241 full time 4wd
BW 1370, BW4401 and BW4470(borg warner)
6boxes used, the tag on the box is what it is.,for sure.
the 205 is for off road only
step one, under car rear of TC (transfer case)
that tag learn to know the tag model

1994 Silverado died and has no spark or fuel.
Does your check engine light illuminate in the run position, key on engine off? It should do a "bulb check" by illuminating key on engine off. If it does, now would be a good time to scan it for trouble codes. If it does not illuminate, and you cannot communicate with the ecm/pcm with a scan tool, you need to start by locating a wiring diagram of your ecm, or pcm, whichever it contains. Once you've located a wiring diagram its time to find your ecm/pcm, remove the electrical connector and start checking your powers and grounds to the ecm/pcm. Use a test light that has a significant amp draw to test your power feeds, an ohm meter can deceive you by showing 12v, but that wire may be cracked and full of corrosion, preventing sufficient current flow. You can use this same method to test the integrity of your ecm/pcm grounds by connecting the end of your test light to positive battery voltage, and touching the tip to the ground pins of the connector. If you have good power and grounds, the fault lies within the ecm/pcm.

Diagram of the fuse box
You will find the fuse box diagram on the the inside of the fusebox cover. It's also available at this link: https://www.autogenius.info/gmc-sierra-mk1-1993-1994-fuse-box-diagram/
