\'93 Bronco T case

I have a '93 Bronco with the Warn manual hubs, with a push button 4WD. There have been a couple times where it took several pushes of the button to engage, but it always worked. Today, it was working (the button and the light), but I realized the hubs weren't locked. So I stopped, got out, and locked in the hubs. Now when I push the button, nothing...no sound, no light. I tried unlocking the hubs, and the button still doesn't work.
I felt so good yesterday after replacing the blower motor (the heater on the two lowest settings sounded like an animal was stuck in there), and now my 4WD doesn't work.

Is this something major? Like the T case gone bad.
Could I have knocked a wire loose replacing the blower motor?

"The frost, sometimes it makes the blade stick." Ok..we watched the Gladiator again last weekend, so that comes to mind....these electric selectors stick from time to time preventing the shift drum from rotating (1356?). This is the unadvertised use for the other end of Crescent wrenches or a ball peen hammer if you have one...go knock gently around the shift motor...in icy weather these freeze from time to time. I dont recall if theres any exposed wiring since the only time I was ever down there looking specifically it was damn cold AND wet...I'm sure someone else could line you up with more detail if its not a frozen motor. Have you ruled out the fuses to the lights on the dash? Are you positively engaged in 4wd?

I'm pretty sure the 4WD isn't engaging. I spun the wheels on snowy, icy roads and it fishtailed, which it doesn't do when the 4WD is working.

One way to find out for sure is to disconnect the rear drive shaft and see if the truck will move in 4wd. Of course, this isn't exactly the easiest or best way, just a way

. Another, easier way would be to unlock the hubs, try to shift into 4wd and crawl while someone looks at your front drive shaft for movement. Anyway, my advice would be to make sure it really isn't working, which it prolly isn't. Either way, I hope you get it fixed cheap and painless.

Well, after having it running for 15 or 20 minutes, the thing started working again. I guess it was a case of the weather affecting it; we've been averaging about 8 for a high the last week.

I take that back. It did work again for me like I said in my last post, but today....it worked at first (despite the temp being about -10), then it stopped working.

I had to dig my Bronco out of a 16" snow bank

. That's right, a 16" (inch) snow bank in my driveway. Talk about embarrassing. Fortunately no one saw me (especially my Chevy-loving neighbor). This really stinks.
I have an appointment with my mechanic to have it looked at on Monday. This is way out of my league. As I said in an earlier post, I got excited when I changed out the heater blower motor and it worked.

Heres some reading...its not mine, but was posted a while back on this forum and you could likely find more with the search function:

Was hoping your fix was just a cold motor needing a kick in the pants, but if its chronic, it sounds like its going to be coming off for inspection.
