hi i have a 97 f150 when i turn the **** on dash nothing happens???? how can i get this to work?? should i replace ****?? should i change a fuse? if so what fuse idk what to do

 

The owner's manual has a complete fuse chart. If you don't have it you can download it.

Normally with mine you har a clicking noise and then a second one. The first one is the electrical, and the second is the 4wd engaging. Pretty much just look it over on the manuel. Out of all the things on my truck thats the one thing i hate (i have a 97 also) is a **** for the 4x4. I wish it was one of those floor shifters cause they dont depend on electricity to use it.

 

welcome to the forum!

probably just a fuse. a light will come on in the guage cluster when it is in 4wd

 

i checked fuses and they are fine. what about the ****/switch is that what i should check next?

 

Could be corrosion on the gem module connection. Could be a bad gem. I had the same thing on my 97. It turned out to be the gem.

 

check the vacuum lines that go to the front differentail for cracks or leaks

 

Check for voltage at transfer case motor connector. If voltage detected, motor or tranfer problem. If no voltage gem or speed sensor problem. That is if you hear no clicking when flipping switch to 4hi or 4low.

 

yea no clicking at all

 

Is anything else not working right. Interior lights working like they should, auto window down working. I know it sounds funny, but the gem module controls these things. Ford had a problem with the gem. I have a 97 also, replaced gem 6 months ago. I finally took it to the dealer and had them put on the computer. I had a short circut in the vss circut. New gem and it is working fine.

 

everything else works other than my tailgate haha i cant get it to open

 

Does the 4x4 indicator light come on in the dash?

 

yea it comes on when i turn truck on but not when i turn ****

 

so where can i veiw how the vacuum hose runs?

 

My shift fork in the front diff that engages the 4x4 broke on my truck. Dealer replaced it under warranty. Difference is that my light came on in my cluster. The truck still thought it was in 4x4 even when it wasn't. I would turn the **** and the light came on, but no clunk sound of the front diff engaging.
