The temperature doesn't seem to hold consistent meaning if I set it at 70 it will blow cold then not not steady. Is their a sensor inside I should check and clean?

Any suggestions appreciated.

that maybe normal. If you set it at 70 and the temp inside the cabin gets to 70, then the air will start warming up until it goes above 70.

Part of the AC system is the light sensor on the dashboard. it may blow colder when your facing the sun, but as you turn your car away from the sun and face shade, then the AC may blow warmer air.

as long as it feels like its 70 inside the cabin, then its doing its job.
