'02 AWD disable light on. Need advice.

[Monty66]

I have an 02 Venture. About a year and a half ago the AWD disable and ABS light came on. I had a rear wheel bearing going out so I replaced both rears and everything was fine. This summer one of the front wheel bearings was getting quite noisy and the AWD/ABS light was on again. I replaced driver side front and the lights went out for about 2 days and came back on.

In the meantime one of the rear bearings I changed 1 1/2 ago was getting real noisy again so I replaced it and the ABS light went out, but AWD disable is still on. I replaced the other front bearing (only one that had not been changed) and now the van drives quiet again but the AWD light persists.

AWD disable comes on before you even move the van so I am ruling out some of the odd problems I have read about speed sensors not working right or odd sized tires.

I also crawled underneath and checked the wire harnesses under the driver seat area and they all look like new.

Any ideas what would cause AWD light but not ABS?

While test driving, went to clean the windshield, wiper mechanism died. Then garage door opener broke. This ain't my week.

Any and all help appreciated. Thanks. Tom
