4x4 questions

[hunter07]

i have a 92 explorer and the 4 wheel drive doesnt work. I checked the module in the back and it tests good with the blinking light. but when i push the 4wd switch i dont hear any clicking. could somebody tell me where i should look next.

also does anybody know how to fix the gas gauge, mine reads empty all the time.

Thanks

I got a used switch off ebay and that didn't help, i checked and i have power at the swith plug in.

check your connector at the transfer case. Fuel tank sending unit sounds like its bad.
