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.

Is the light still blinking with the ac system working at this time? Do all the modes change as commanded?
