97 Blazer-4wd blowing fuses?

press1280 · 02-18-2007, 09:38 AM

My 97 has blown about 4 fuses thus far for the 4X4. Problem is,when you put a new fuse in,everything works fine for a little while(like maybe a few days). It's the next time you go to use it after you haven't for a while that you find it's blown. Is it the actuator or some kind of electrical issue?

Been gone for a few weeks. It happened again the other day when it snowed. Tried to get 4 HI and the 4HI button flashed a few times then nothing.Did it again,same thing-flashed then nothing. Then tried it again,just a click. Checked fuse,its blown.Put in a new fuse-went right to 4 HI like its supposed to. Nobody's had a similiar problem?

Mine does that too, except the fuse is fine, unless there is another fuse.

I actually parked mine (technically my wife did it because it's hers) with 4lo engaged. It sat for a week until I drove it again and it didn't want to come out of 4 lo for about 15-20 minutes of driving, then I got it into 2HI and now 4lo and 4hi don't seem to work. Sometimes the 2hi button is lit up, sometimes not. Sometimes when I push the 4hi button they all flash and go right back to 2hi, sometimes nothing happens and it just stays in 2hi.

I had a problem with the 4wd computer connector corroding. I would hear constant relay clicking as I was driving, and the 4wd lights would flash. Took me a while to figure out where the computer was at. Once I did, I took it out and noticed corrosion on the terminal connector. Wire brushed and greased them, and haven't had a problem since.

Point being, corroded terminal may be your culprit too.

I am having the same problem. Every time I hit 4HI, the light on the button and my cluster and interior lights go out as well, all because it blew the fuse out.

I keep researching that it might be the front axle actuator, or maybe a short in the line somewhere.

What someone told me: buy a circuit breaker for it.

I had the same thing happen to my 96 Jimmy. It was the encoder motor. It is on the transfer case and it actualy shifts the case when you push the button. the dealer wanted 500.00 plus labor. I got a GM one for about 250.00 and it took about 1 hour to put in.
