Good afternoon my name is Roy and I will assist

Does the A/C system produce cold air? You may have an issue with the A/C system such as, low Freon, leak in system or compressor.

Ok I don’t know that on newer vehicles that don’t have a inspection window.Look for leaks,broken lines nothing around condenser.stared it up & it got cold came to temp turn on heat & its ok. But I still don’t understand why the a/c light flashes & turns off when its on auto. No mention of this in the manual. I had someone say it’s the mixture door? Any way thanks again.
