I have a 1990 Chevy Lumina 3.1 I have no heat the blower blows but does not blow hot air my coolant is fine and the engine temp is at normal operating temp. I have flushed the core and run Prestone Radiator Flush as directed. I can feel a change in air flow when I move temp control to Heat and select Heat. Also, if I switch to defrost, the compressor comes on but air does not switch from front vents.
have the same problem?
