Climate control system blowing hot air
I have a recent issue with my 2010 Ram and hope someone here can advise me.
In the last several days now my system has pumped out hot air regardless where the control is set. I can not even get the air conditioner to work. Of course it has to happen with the weather in the mid 90's!
The last time I used the A/C was a year ago and it worked fine. Have had cool air blowing throughout the warm days of Spring.
It seems to be blowing heat rather than just hot air.
The check engine light is not on.
Radiator is full and good to -40.
Controls on the dash seem fine.
My initial thoughts were the A/C needed recharging but while speaking to the service place they thought it might be a valve that is stuck with the heat open. The A/C recharge is on hold.
Would there be a code registered but not showing a check engine light?
Would a simple Coolant System flush clear this issue or is it a more serious problem?
Of course I am just out of warranty due to mileage.
I have run out of ideas on this one and would appreciate some advise.
Nice truck otherwise.
