My 06 Sebring convertible is having issues with the heat/ac

Customer Question

My 06 Sebring convertible is having issues with the heat/ac mode. The fan speed dial works fine, as does the tempurature dial. But the mode dial will no longer control where the heat/ac blows from. It will randomly change throughout the time it's operating, and can self-adjust when hitting a bump in the road or pressing the brake/accelerator too hard.

I do not have an automatic heater in my car. As I started in my original question, I have the separate dial control knobs that individually adust fan speed (left), temp (center), and mode (right). The right mode dial is the only one that doesn't function properly. Does this change anything in the suggestions you provided? I do not want to waste time/money attempting to repair an automatic control panel system when I clearly stated that I have a 3-dial unit.

Expert:  Chad Farhat replied 1 year ago.

yes that is the one ,I have changed more of the units in my shop that i can remember , they just fail, but you have to do the checking i mentioned above

get one from local junk yard and return it ,most give 30 days warranty if it doesnt work , u can take apart some time and see any burned spots, but here in sc , i can buy them for $35 used

on ebay if you want new be cheapest

Thanks!

get a test light check for power to actuator first make sure u have power , then listen inside the cab for noises from dash indicating a broke gear of actuator ,

the a/c unit head will be hard to check if you dont have proper equipment , we just changed if old and we know it is common problem if the other stuff checked out

if you want to check for ground you put your test light lead connector on positive side of battery terminal so anything u touch if it lights up You have found ground

you hook up the test light lead connector to negative side of battery then when u touch anything and lights up you found voltage or power :)

good luck

let me know
