Heater control flashing

After a recent battery change the ACC display starts flashing aprox. 30 secs. after eng. is started, then clears ok after a further 30 secs. Also I only get heat out of the driver side lower outlet.

Shay, I had the same problem. My solution was to warm up the car then turn it off. Make sure the passenger side air vents are open. Disconnect your neg battery cable for 90 seconds then reconnect. Start the car and see if your problem is resolved. If not do the same procedure with the battery cable but with the ignition switch in the on position (motor not running) Let us know.
