Electrical problem
1992 Cadillac STS V8 Manual

problems with car, no ac/heat in vehicle, light is on, but nthing comes on with ac/or heat. I had replced the heating core last fall, and still nothing. checked fuses, not the fuses. i put a new battery in and alternator. sometimes with electrical acting up my alarm goes off sometimes, and won't start. Have to wait 20 min. to start car up.

By no heat/ac, do you have no blower operation?
