So I had my batter disconnected for a day while my car was getting the floor board welded. After reconnecting the battery I've noticed my heater is working a bit differently. If I put it on 18c (coldest setting without ac on) the air comes in cool, but if I raise it to 18.5c it comes in hot, no in between anymore either hot or cold. Never used to be that way, any idea what it could be guys?

 

bueller....bueller

 

Try this:
Step 1.
When holding the AUTO + RECIRC buttons together, turn on ignition lights (dont start). Any error codes will appear. 21 & 24 will appear if it is dark out(solar sensor).
Step 2
Press RECIRC and let the system do the auto-calibration cycle. Let this run 2-3 times, turn ignition OFF then start her up and see if it works!!!

 

Ill try it tonight! Thanks

 

Error code 11, still does the same thing tho cold at 18 hot at 18.5
