had this same probelm on my wifes 2009 H3. bought the thermostat and before i started to replace i noticed the coolant level was real low in the overflow tank. filled it to the operating line and the AC Off light went off and hasnt returned... gonna save the thermostat for when i replace the waterpump. try this first as its the easiest thing to check!

edilowks did you ever fix it? I been having the same issues for a year man. Im getting check engine light with only one code p0651. Its driving me crazy. It only happens when the temperature drops below 30 degrees.

How much did the part cost. Think it will be an easy fix for someone that's not mechanically inclined, or should I take it to be fixed. Seems pretty straightforward.

I actually did the same thing for about six months eventually you will only be able to go 7 miles before it happens again then you're going to have to change thermostat

I actually put a battery cut off switch on my negative post so I could flip the switch flip the switch back on so I didn't have to keep loosening the battery terminal eventually it got to the point where I could only go 7 miles and it would do it again

How come a defect thermostat has anything to do with it, it either lets the water flows all the time not letting the engine warm correctly or not, letting the engine overheat,, neither way makes the temperature gauge not to move...

embrj145 after I changed the thermos stat sensor it kept doing the same problem I took it to AutoZone in my area they plugged it in to their machine told him it was the thermostat I asked the guy why the thermostat whatever anything to do with it it's all connected to the computer if the computer doesn't sense The right temperature for the vehicle it throws the code the thermostat was stuck in the open position so won't heat up enough to trigger it so if you want to be sure that your problem take it to an auto parts store that will diagnose it with the machine all I can say is it work for me haven't had a problem with it sense

embrj145 go out and take care of negative battery cable off wait a few seconds put it back on it will clear the code then drive 7 to 15 miles or if it throws the code again driving a few more miles disconnect the battery that will clear the code or the vehicle will be hot enough by then The AC will start working again and the temperature gage will go up enough for the computer not to throw the code try that
