AWD went out!

[ColoSVXer]

I will check to see if a fuse is inserted today, but I doubt it because I do most of the on my SVX. I was wondering also if it might be because I have a different brand tires (same size) on the front and rear and have read the size must be => 3/32". Still, it runs great, shifts great and no noise, except the rear wheel bearings are started to get a bit noisy. Since its a 1996 and does not have the "Power" light, I read to see if the AT Temp light flashes when first starting and it does not. Even tried to see if I would get any codes per BudFreaks instructions. Nothing.
