Hello, I have a '97 SC2 w/50k miles. Auto-trans.w/air con. No other power equipment on car. Live in the midwest, USA, and it has been very hot here lately so I have been using the air con. every day w/no problems. Sat. night I was on a trip about 15 min.'s, the temp. was only in the 80's outside, and the warning lights above the temp. guage started flashing. The temp. guage was in the normal range. Not hot. I checked out my manual and it says those lights are a "combined high engine coolant temperature/automatic transaxle fluid temperature/low coolant level warning light." So that must mean there are three sensors that could trigger the warning light. So how to tell which is the problem? When the lights first started flashing I turned off the air. con. and after about 30 sec's the lights went out. So I figure the coolant is too hot....but the guage needle is in the normal range and the sensor to that guage has been replaced by new a one quite recently. I let the car cool and checked the coolant level and it is right where it is suposed to be. That fluid was changed after 5 years. I also checked the auto. transaxle fluid and it is at the proper level. That fluid was also changed at 30k miles. The next morning I drove the car with the air con. on and the warning lights came on again after driving only 2 miles. I turned off the air con. again and the lights went out. Later in the same day when the outside temp. was over 90 dgs. I drove the car for an extended period and the lights never came on again and have yet to come on again so far. Any thoughts, ideas, or similar problem? Thanks, Dan.
