ECC flashing-air mix act good

Post by adinini »

I removed my battery the other day...now my ECC flashes and my heater doesn't work. My air mix actuator is working fine but it defaults to cool (smooth operation) about 5 seconds after I start the car. Can you reset the ECC?

Thanks

I know if you unhook the battery, sometimes it'll make the ECC flash at you. But is there some sort of reset on your year... I don't know. Hopefully someone that does will chime in.

I may be wrong but from my own experience with this exact problem, after so many drive cycles I found that it just stopped flashing and resumed normal operation I hope you are as lucky as I was. this was on my 98 lesabre
