Why would the check engine light illuminate on a 1990 Chevy Corsica only when the max heater or defrost is activated and the normal HVAC works fine?

look at the o2 sensor. the motor slows down and may cause the reading. you can take it to a parts store and ask them to run a computer scan and see if it can identify the problem. they ususally don't charge for the scan. they want to sell you the parts for the problem. The age of you vehicle may require a special scan tool. After 1996 all vehicles were required to have an obd2 connection. before that most had an odb1. hope it helps. duboff
