AC/Heater Problems

Was hoping someone could help me out with a recent issue I'm having with my 06 Max. Over the last couple of months, the heater has stopped blowing hot air. Even on the highest setting it will only blow luke warm and will not warm up the inside cabin properly. I also noticed that the air conditioning will not blow cold air. I'm not sure why this has happened all of the sudden. All of the heater/AC controls seems to be working properly.

Any help would be greatly appreciated.

Thanks in advance.

The heater problem sounds to me (feel free to correct me if I'm wrong) like a bad thermostat.

Regarding the AC, have you ever had it charged? If not, it may just be time for a recharge.

No. I have not had the AC charged since I have owned it. I bought the car approximately a year ago. It has 67k on it now.

might be thermostat since no heat and a/c, but remember the orginal a/c low pressure hose is prone to leak. I just replaced mine and still need to recharge it.

I have an '06 with the same issues. The heater won't blow hot air unless I'm driving. When my car is idle, the heater blows cool air even at the highest temp. My air conditioner blows hot air even at the lowest temp no matter if I'm driving or not. My air conditioning problem is a cracked A/C hose. I totally forgot to tell the dealership about the heater problem. Your best bet is to take it to the dealship and have it diagnosed. It can be something simple like you may just need Freon to, like my car, the hose may be cracked and needs to be replaced.

I've disconnected the heater core on cars in the past and blew compressed air through it. They get clogged up sometimes. Also, look into flushing your coolant and changing the thermostat

This is what you do you right but only if you dont have a leak, cause if you do have a leak you will change that and all you need it done was the hose so check with your mechanic to see if you have a leak with that big machine they have and go from there, if is no leak then you check radiator if that is good change thermostat but only if there is no leak good luck.

you might have air in your coolant. Park on an inclined driveway with the nose of the car facing up. With the engine cool, remove the coolant cap. Do not take it off, just loosen. Start your car and turn your heat up full bore. Watch the cap to make sure you are not spewing coolant all over. Once the heat starts to come out very hot, then shut the car off. If this doesn't happen before the car is at normal operating temp, then it is surely your thermostat. Sometimes, it can be the flap that changes from the air conditioning to the heat that gets stuck half way. Not very often, but can happen. It sounds to me more likely an air bubble in the coolant. good luck. if you loose some coolant, just top it off with some water.
