Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is***** am an ASE master tech, glad to help you out with this.
Whenever you have a problem cooling at idle, it is usually the electric cooling fan not working or the ac compressor is bad.
A pressure check at idle with the ac on would verify this. Also check that the electric fans come on whenever the ac is on. They should be running on low speed at all times. Also make sure your ac condensor is clean and free of debris.
I would check the fans first on this.
