Check Engine Light Question?

I own a 1999 TJ 4.0 and was wondering if anyone has had a problem with the check engine light coming on when the jeep's heater is turned on. I have reset the check engine light and it goes out and stays out until the heater is turned on. Could a bad blower motor cause this to happen? Any help will be greatly appreciated. Thanks.
