Can't locate where the cruise control module is on 2002 Audi S4.

The fuel pump fuse is located in the engine bay fuse box. It is the 2nd row from the top, last fuse on the left.

If they are like other Saturn's, it's attached above the glove box.
Remove the glove box door, and the screws that attach the plastic box to the dash, then pull it down and towards you, the BCM should be on top. It slides out of its holder.

Could be in the electronics box under the right side engine cover or in the vicinity of the glove box (behind or over).

Here is the e-box:

When you are talking about "indicators" we could assuming that your are refer about signal lights. This work with "flashers" devices.

About generic fuses, open the driver side door. Remove panel on left side of dash. Fuse box is behind panel:

Bad blower motor or loose electrical connection to the blower motor - My 98 A4 usually required that I slam the glove box in order to get it to work.
