Re: AWD disable light on in Rendezvous Buick? he is talking about the AWD light only. if this is the only one, it is the oil temperature. Check your owner manual, it is inside. I got my AWD light on one time, good thing my car was on warranty, they changed the rear diff, but it was not the GM warranty.

Covalent bonding is one kind of linking that joins atoms together. The group of atoms held together by covalent bonds is a molecule. The example you are most familiar with is the compound water: water consists of covalent molecules, i.e. it is a covalent compound. Recall what is in molecules of water from Section 2.5.
