Hello. This is my first post, but have read most of them. This site has helped me with a few problems since i got my truck, but this one i have not found the answer to.
2001 1500 4x4 5.2L
The 4wd light comes on only when I am in 2H. N, 4L, and 4H the light stays off.
The 4wd and 2wd work fine, i tested with a little gravel pit fun.
I have had the truck for a little over 2 weeks now and just noticed today because it was the first time i thought i might need 4wd. So in the last 2 weeks i have put about 1000 miles on 4H. Might explain the 13mpg.
I have looked in the service manual that a got from a link somewhere on the forum. It basically says (if i understand correctly) that when the front axle vacuum pump engages the axle it hits a switch to ground the light on the dash.
Soo if there was a short to ground in the wire, the light would stay on constantly. If there was a bad ground or a break in the wire, the light would never come on. And if it were possible to plug a connector to the switch in backwards the light would still operate normally.
So what could cause the light to be completely opposite? Any Ideas
