The temperature gauge in my 2003 toyota solara has been staying in the cool area. It does not move. The heat in my car hasn*t been as warm as it usually is. Today my check engine light came on. What could be the problem?
Check the level of your coolant and make sure it is full, coolant levels affect the heater and air conditioning. To determine the exact cause of the check engine light coming on, take it to a Toyota Dealer and they will hook it up to a computer and diagnois the problem. There could be several reasons why it came on.
