My heat and ac won't come on unless set at full setting in my Oldsmobile Silouette. It started doing this at the first setting then the second and so forth until it won't blow out unless you turn it on full.

We just had this happen to our 1997 Olds Silhouette. We went to Auto Zone and bought a Blower Motor Relay switch, which was very inexpensive. It's located under the glove box. It wasn't very hard for my husband to replace it, either.
