SOURCE: location of the Heat resistor in a 2003 Chevy Malibu?

Under the glove box, behind the blower motor itself. Remove the shroud below glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the purple/black power connector to it - - you'll need this extra room to work with. 2 more screws, same size, 6.5mm on mine, 7or 8mm on some others, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage - up to $400, what a sham.

Check the fuse it may need replacing.

Cheak your fuse under the drivers side under the hood. Look in your manuel for fuel fuse. It looks like a little black box.

Only if theft light is flashing, then it would need to be reset, to reset turn key to on and wait till theft light stops flashing about 10mim or so, then turn key to off and back to start engine.
