My blower works, but it blows cold air not hot air when I try to use the heater. The temperature on the dash reads 185F for the external temp and 80F for the internal temp. It is only about 45 degrees outside so, of course, my car is not 80F inside. I called the dealer's service department. He told me that it could be the sensor under the hood. What do you think?
