97 S-10 Blazer electronic 4wd blows fuses

[cybermoser]

My 4x4 is giving me problems. Every now and then when I go to push my electronic button into 4HI or 4LO the 4 wheel drive button flashes about 3 or 4 times and then it goes back to 2 wheel drive. If I keep doing this a few more times it blows the 4x4 fuse!! And then other times it works just fine.

I was up in the mountains of Colorado this weekend and I started up a 4wd trail and after rocking and rollin for about 1/2 hr. I decided maybe I should put it in 4wd, I pushed the button and it just flashed for about 5 sec. I pushed it again and again and it blew my 4wd fuse, so I left it in 2wd and replaced the fuse. I let the vehicle set for 3 days in the mountains and on my way down yesterday I tried it again and this time it went into 4wd! weird huh.

I really need to get this thing fixed, please help.

This may help you!!
My silver hates to lock up when you want it,what i do is role it out so that it is on flat ground then take it out of gear,let it roll this takes out the torque in the drive train,then hit the go button and put it in gear and let it roll out then hit the trail. This is an electric motor that does all this the gears need to match up and mesh with the gears if they don't you will over load the servoe. Or you could just put in an after market manuel twist and lock job,,, that would make more sence .
