Almost sounds like there could be air trapped in the radiator coolant system. Has it recently been serviced or the coolant changed?It’s freezing outside, 0 degrees. Start the car, driving about 5-10 minutes and heat starts get warm inside the car. When stop at stop light heat starting blowing cool air. Start driving and heat gets warm again after 7 to 10 seconds. Normal?
Good to hear you are back to being fully functional. Sounds like the mechanic didn't want to share all the details.From my original post. Heat is fixed. Blowing hot now. $65 my favorite mechanic. What I didn’t understand was he said “it was plugged “. What was plugged?
