and thanks me to help you today. I am a licensed diagnostic and repair technician, I look forward to working with you.
Sorry delay getting back to you!This problem is very strange, it's not something I would consider to be normal operation. Some vehicles will shut down certain systems reasons so if your model is fitted with an economy button. Try running with this switched off.If the problem still occurs I suspect there may be a problem within the climate control system which the dealer will need to look into. I understand they are not always that helpful so my best advice would be to ask them again if this is normal and ask them from documentation explaining this.
If they cannot give you this. Accept that it is not normal and ask them to investigate the problem under the manufacture warranty. You can also put in a phone call to Mazda customer services, they will be helpful and can work between you and the main dealer to get the problem corrected.
