Today i went to hook up my 03 blazer to my snowmobile trailer. Pulled into the yard in 4-HI and it seemed fine. There was about 6 inches of snow but nothing more. The tires stared to spin. Had a buddy look at my front tires and they wernt even moving in 4-HI or 4-LOW.

Has anyone had this problem? I think it might be something computer wise. I dont think my 4wd buttons are actually putting the truck in 4wd.
Thanks

 

Typical problem, check out the 4wd no worky thread in the Tech Article (DIY) Index linked to in my signature.

Wow thanks. I guess i had a vaccum un hooked when i did my wiring for my amps. Thanks

 

having similar problem with 06 blazer with plow 3 button switch on dash was stuck
in 4whl low but 4 whls weren't pushing I bought a new 3 button switch at napa $28. cause it seemed to be acting up and they are known to cause problems.
It didn't fix the problem but at least works better than the old, Moving on to what
is called a vacuum valve that is also known to stick I don't know what it looks like or its location but I 'm going to advance auto for a free engine code scan
