Heater not working,but lights are on and power.
SOURCE: 1992 BUICK LESABRE LIMITED, NEED FUSE BOX DIAGRAM
the fuse is in panel with other fuses,however it will say a\c instead of heater. You may want to use a test light to check for voltage at the blower motor plug. To see if current is going to the fuse. Check the other fuses too. since they are linked in parallel to the the acc auto climate .
It
can be faulty brake light switch causing the problem or its wiring short for switch.
