Where is the blower motor resister on a 1995 Cadillac Seville STS?

An unemployed friend of mine has a 1995 Cadillac Seville STS that he inherited. The blower motor does not come on, and he was told that the blower motor resister is probably bad. He cant afford to take it to a shop and wants to change it himself, but we do not know where it is located or what it looks like. Can anyone tell us where the blower motor resister is located?|||Usually, it's located within the blower motor itself, a small square piece with curly coil and wire terminals. Try no to touch the coil, it snapped easily. Good luck....|||The blower motor is under the hood, on the firewall.
